| Tool | Description | Behaviour |
|---|---|---|
| add_business_days | FREE, unmetered. The date n business days after (or, for negative n, before) a start date. The start date is day 0 and never counted; n = 0 returns the date itself if it is a business day, otherwise the next one. Lists every non-business day skipped and why. Uses the country's national public-holiday calendar and its statutory weekend rule (Gulf Friday+Saturday, Israel Saturday-only, India 2nd/4th Saturdays, Nepal's 2026 change, China's multi-day breaks and make-up working days). A date in a year whose holidays we do not hold is refused with error year_not_held and the years_held list; it is never computed from weekends alone. A statutory holiday whose date is not yet fixed is refused as holiday_date_pending. Regional (sub-national) holidays are not applied. | Read-only |
| business_days_between | FREE, unmetered. Business days between two dates. business_days counts (from, to] and is negative when to is before from, so add_business_days(from, business_days) lands on to whenever to is a business day; business_days_inclusive counts both ends. Also returns weekend days and the public holidays in range. Uses the country's national public-holiday calendar and its statutory weekend rule (Gulf Friday+Saturday, Israel Saturday-only, India 2nd/4th Saturdays, Nepal's 2026 change, China's multi-day breaks and make-up working days). A date in a year whose holidays we do not hold is refused with error year_not_held and the years_held list; it is never computed from weekends alone. A statutory holiday whose date is not yet fixed is refused as holiday_date_pending. Regional (sub-national) holidays are not applied. | Read-only |
| check_minimum_wage | PAID ($0.05). Compliance verdict: is a salary at, above or below the country's statutory minimum wage? Returns verdict, margin, the statutory floor and the legal instrument it rests on. Honest statuses when no enforceable floor exists or the period doesn't match the floor's period (cross-period conversion is never guessed). Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. The evaluation country is free to try (see list_series). Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| compute_employment_cost | PAID ($0.10). Cost to employ: prices every statutory contribution on both the employee and employer sides for a gross salary, returning line-by-line amounts with instrument citations and an explicit refused list for schemes that could not be priced (unknown, not zero). Does NOT compute income tax — use compute_payroll for gross-to-net take-home where supported. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. The evaluation country is free to try (see list_series). Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| compute_income_tax | PAID ($0.05). Statutory income tax on a TAXABLE-income figure using the country's verified marginal bracket schedule, with full per-bracket workings, effective rate and marginal rate. You pass the amount in local currency. IMPORTANT: this is tax on taxable income, NOT net take-home pay — reliefs/allowances and social-security contributions are the caller's concern and are not applied (see the response scope_note). Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. The evaluation country is free to try (see list_series). Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| compute_statutory_interest | PAID ($0.05). Simple statutory interest on a principal at the cited statutory-interest series rate: Actual/365 simple, principal × (rate/100) × (days/365). Pass days, or from and to as YYYY-MM-DD (from inclusive, to exclusive). If both are sent and disagree, the call is refused free. A series with no numeric rate after materialization (mechanism-only) is refused free — a non-answer is not sold. Not legal advice. Jurisdiction-specific compounding and day-count statutes are not applied. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. Every AE series is free to try. Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| compute_vat | PAID ($0.02). VAT breakdown for an amount: net, tax and gross using the country's current statutory rate, including per-levy components where the rate is composite (e.g. Ghana VAT + NHIL + GETFund). mode=add treats the amount as net; mode=extract backs VAT out of a gross amount. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. The evaluation country is free to try (see list_series). Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| count_working_days | PAID ($0.02). Working days in a date range for a country: weekends (Egypt's Fri–Sat handled) and statutory public holidays applied, with the holidays hit by name and the next working day after the range. Range max 366 days. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. The evaluation country is free to try (see list_series). Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| get_calendar | FREE, unmetered. GET /v1/calendar for this brand's continent. Optional country (ISO 3166-1 alpha-2) and series. Derives reverify_by from last_confirmed + update_cycle_days (the same window that sets stale) and, only when current.effective_to is a non-empty string, next_effective_known with basis effective_to. status unknown omits that date. Never parses notes. Does not invent MPC, budget, or wage-review dates. next_effective_known is the recorded end of the current value, not a promised gazette event. A 402 is a gate bug — do not pay. Past changes stay on get_changes. | Read-only |
| get_changes | FREE unmetered change + freshness feed. After any paid series or answer call, call this before you assume the cached value is still the law. Returns every series whose current value took effect on or after `since` (default last 30 days), newest first, each with last_confirmed and stale, PLUS a dataset-wide freshness summary: how many of the served series were re-verified within 1/7/30/90 days, how many are past their window, and which single series has gone longest without a check. Freshness is checkable or it is marketing. Args: since? (YYYY-MM-DD). Do not re-pay get_series to discover a diff. For a push bind, use register_alert (Register: $0 · Delivery after trial: $0.10). For a filing freeze of the current value, GET /v1/certified/{country}/{series} ($0.25). | Read-only |
| get_filing_deadlines | PAID ($0.005, same as any series). Recurring statutory tax deadlines for a country — VAT/GST returns and payments, PAYE/payroll withholding remittances, corporate income tax returns and provisional/instalment payments — as RULES, each cited to the official source with the verbatim phrase that states it, plus the actual DUE DATES in a window, rolled for the country's weekend and national public holidays (every skipped day is listed). Where a rule's source does not say which way a weekend deadline moves, the date is flagged roll_unverified rather than guessed. Countries or taxes we could not verify are returned as a free coverage_gap with reasons, never invented. Pass year_end (MM-DD) to re-anchor corporate-tax rules on the company's own accounting year end. The HTML page /{country}/filing-deadlines shows the rules free. Every AE series is free to try. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.10) on this series so a later gazette does not silently retire the value. | Read-only |
| get_key_balance | FREE. Remaining allowance for an API key (free, card or metered): plan, quota, used, remaining, reset date and what the key covers. Never metered. Pass api_key, or send the key as the X-API-Key header on /mcp. | Read-only |
| get_public_holidays | FREE. Official public-holiday calendar for a supported country, including gazetted movable holidays, with the official government source cited. Some countries also carry sub-national calendars (e.g. the German Laender): the `subdivisions` field lists them, and passing `subdivision` (ISO 3166-2, e.g. 'DE-BY') returns the national calendar merged with that region's statutory days. | Read-only |
| get_public_holidays_worldwide | FREE with any API key, including the free key by email (https://mearef.dev/free-key). Same as get_public_holidays, but for every country across all seven brands, not only Middle Eastern. Unmetered: never counts against the key's allowance. Pass api_key, or send the key as the X-API-Key header on /mcp. | Read-only |
| get_series | PAID ($0.005). Current value of a reference series — e.g. series=policy-rate, vat, minimum-wage. Every value carries its official source citation, effective date, last-confirmed date and staleness flag. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. Every AE series is free to try. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.10) on this series so a later gazette does not silently retire the value. | Read-only |
| get_series_history | PAID ($0.005). Historical values of a reference series with effective date ranges, optionally filtered by from/to (YYYY-MM-DD). Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. Every AE series is free to try. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.10) on this series so a later gazette does not silently retire the value. | Read-only |
| get_snapshot | PAID ($0.02). Snapshot of every series for every country in one call. Pass api_key if you have one (instant card checkout at /pricing); otherwise the response explains how to pay via x402. Every AE series is free to try. After a 200, bind get_changes (free poll) or register_alert (HMAC push; Register: $0 · Delivery after trial: $0.10) on this series so a later gazette does not silently retire the value. | Read-only |
| is_business_day | FREE, unmetered. Is this date a business day in this country? Returns is_business_day, the reason (weekend, public_holiday, makeup_workday…), the holiday names, and the next and previous business day. Uses the country's national public-holiday calendar and its statutory weekend rule (Gulf Friday+Saturday, Israel Saturday-only, India 2nd/4th Saturdays, Nepal's 2026 change, China's multi-day breaks and make-up working days). A date in a year whose holidays we do not hold is refused with error year_not_held and the years_held list; it is never computed from weekends alone. A statutory holiday whose date is not yet fixed is refused as holiday_date_pending. Regional (sub-national) holidays are not applied. | Read-only |
| list_series | FREE. Catalog of all mearef reference-data series: supported countries, series ids, descriptions, freshness metadata and per-series URLs. Call this first to discover what data exists. Paid answer tools accept receipt=true (included in the answer price, no extra USDC) and, on a paid success, return an Ed25519 answer receipt (kind answer_receipt). That receipt is not a series certified extract and is not legal advice. Series certified extracts are GET /v1/certified/{country}/{series} at $0.25 and are not an MCP tool. Verify a receipt with verify_answer_receipt (free, public key only) against /certified/public-key. get_changes is free. get_calendar is free. register_alert registration is free. | Read-only |
| register_alert | Bind a webhook so the next gazette does not silently stale a value you already paid for. REGISTERING IS FREE. Register: $0 · Delivery after trial: $0.10. First 3 deliveries are free; later deliveries are $0.10 and refunded if the webhook fails to send. HMAC-SHA256 signed. Two watch types on the same call: • series: ["za/vat-registration-threshold", "ke/*", "*"] → series.changed when the served value or its effective date moves. On usaref those watches are statutory (minimum-wage, income-tax, statutory-interest, sales-tax, public-holidays), not a FRED-macro subscription. • sources: ["<exact official source.url>"] → source.changed when the document BYTES change (old/new sha256 + citing series). Bytes ≠ value. Value changes arrive as series.changed. Unknown URLs refuse free (source_not_fingerprinted). Max 20 series + 20 sources. Required: url. Optional: api_key stored on the subscription to fund deliveries after the trial. This call does not meter that key. Prefer this over polling get_changes if you are a long-running agent. This is retention, not a new data product. | Changes data |
| settlement_date | PAID ($0.05). Settlement/value date: the date n business days after a trade date, computed on the INTERSECTION of the calendars you name, with a per-day trail showing every skipped day and why, on which calendar. Supply business_days for a cycle you are trading under, or market + instrument_class to have a settlement cycle applied that we cite to its primary source (e.g. US equities T+1 under 17 CFR 240.15c6-1(a); UK gilts T+1 by DMO convention, which is NOT the T+2 equity cycle; Japan equities T+2 but JGBs T+1). Calendars are NATIONAL statutory holiday calendars with researched statutory weekend rules (Israel Saturday-only, Gulf Friday+Saturday, India Sundays plus the 2nd and 4th Saturday), NOT CSD or exchange calendars — each response states the basis and any known divergence. Use 'eu.t2' for the euro cash leg. We refuse FREE rather than guess: beyond published calendar coverage, no cited cycle for the instrument (government bonds never inherit an equity cycle), a cycle not in force on the trade date, or FX spot value dates. Free companion: GET /settlement-conventions. Optional receipt (boolean, default false): on a paid success, include an Ed25519 answer receipt at no extra USDC. An answer receipt is not a series certified extract (GET /v1/certified/{country}/{series} is $0.25 and is not an MCP tool) and is not legal advice. Verify with verify_answer_receipt against /certified/public-key. | Read-only |
| verify_answer_receipt | FREE. Verify an answer receipt (kind answer_receipt) with the Ed25519 public key only. Pass the receipt object or its canonical JSON, signature_value when the signature is not inside the receipt, and public_key_pem to verify offline. If public_key_pem is omitted, the tool may GET signature.public_key (/certified/public-key) and read public_key_pem. Never send a private key. A valid signature shows this service issued that exact receipt. It does not turn the receipt into a series certified extract (GET /v1/certified/{country}/{series} at $0.25, not an MCP tool) and it is not legal advice. Same key and canonical-JSON rule as /certified/public-key. | Read-only |
