Tools
| Tool | Description | Behaviour |
|---|---|---|
| create_account | Opens a new SnapEX Pay merchant account for you and returns a merchant API key with every scope (receive, pay out, convert, webhooks). No captcha, no email confirmation, no person needed. Call it once, only when you have no key yet (other tools answer "unauthorized"). On this MCP connection the new key is used automatically from now on; save api_key (shown once) and use it next time as "Authorization: Bearer <api_key>", or connect to mcp_personal_url. login and password (generated when omitted) let a person open the cabinet at cabinet_url. The account starts with a zero balance; money arrives only from payments to your invoices or addresses. Limited to a few accounts per IP per hour. | Changes data |
| create_conversion | Step 2: executes a preview_conversion quote before its expires_at; the balance changes at once. A preview runs once — calling again returns the same conversion. | Destructive |
| create_invoice | Creates an invoice and returns pay_url — a hosted payment page where the payer picks a coin and pays; the amount is credited to your balance in USDT minus the fee. Give amount_usd, or price_amount + price_currency (converted at get_fiat_rates). Use environment "test" to try the whole flow without real money: a test invoice turns paid by itself about 10 seconds after a coin is selected (on its page or with select_invoice_payment_method); the real balance does not change. Then follow the status with get_invoice or webhooks (invoice.paid). To get a deposit address right away instead of a page, pass asset_id (and lock_method true), or call select_invoice_payment_method. | Changes data |
| create_payment | Creates a payment from a preview_payment quote and returns deposit_address (and deposit_memo when the network needs one) and the exact amount the payer must send before expires_at. | Changes data |
| create_payout | Step 2 of sending money: executes a preview_payout quote and sends real funds from your balance — irreversible once sent. destination_network and destination_address must be the ones of the preview. idempotency_key is required: reuse the same key when retrying after a timeout so the payout is never sent twice. Then follow get_payout (status until completed or failed, transaction_url) or webhooks payout.completed / payout.failed. | Destructive |
| create_static_address | Gets (or creates) a permanent deposit address for a coin/network and optional customer_ref: the same address comes back for the same customer_ref. Every transfer to it is credited to your balance in USDT as a separate payment — good for top-ups. Networks: list_static_address_networks. | Changes data |
| create_webhook | Registers a public HTTPS URL that receives a POST for each chosen event (JSON {id, type, created_at, data}). Returns secret (shown once): verify each delivery with HMAC-SHA256 of "<Webhook-Timestamp>.<raw body>" against the Webhook-Signature header ("v1=<hex>"). Deliveries are at-least-once — dedupe by Webhook-Id. Up to 10 endpoints. | Changes data |
| get_account | Returns the account behind the API key in use: login, the key prefix and scopes, cabinet_url for a person and mcp_personal_url (a secret MCP URL with this key built in, for clients that cannot send headers). Use it to check you are connected to the right account. | Read-only |
| get_balances | Returns the account balance. Every payment is credited in USDT (TRC20 accounting), whatever coin the payer used: available (can be paid out or converted now) and held (reserved by payouts in progress), each as a decimal string and in atomic units. | Read-only |
| get_conversion | One conversion with its status and amounts. | Read-only |
| get_fees | What SnapEX Pay charges, no key needed. pricing: invoice_fee_percent (of a paid invoice; fee_on=customer puts it on the payer), invoice_min_usd/invoice_max_usd, static_address_fee_percent, payout_service_fee_percent; the network fee of a payout depends on the coin and is quoted by preview_payout, the smallest payout per coin is payout_min_usd in list_assets. data: recent cached route fee quotes (often empty; filter by route and asset codes). | Read-only |
| get_fiat_rates | Fiat → USD rates used for invoices priced in another currency (create_invoice with price_amount + price_currency). Without currency returns all rates; with currency (ISO 4217, e.g. "EUR") returns one or not_found. No key needed. | Read-only |
| get_invoice | Returns one invoice with its status (open, awaiting, underpaid, paid, partially_paid, expired), pay_url, credit_usd, the selected coin and the payment attempts. Poll it every 15–30 s while the payer pays, or use webhooks. | Read-only |
| get_invoice_payment_methods | Lists the coins and networks the payer can use for this invoice, with the amount to send in each. | Read-only |
| get_payment | One payment (from an invoice, a static address or create_payment): status (e.g. awaiting_deposit, detected, confirmed, expired), amounts expected/received/credited, deposit address. | Read-only |
| get_payout | One payout: status (e.g. processing, completed, failed; manual_review — SnapEX staff checks it), amounts, fee, transaction_hash and transaction_url in the destination network's explorer. | Read-only |
| list_assets | Lists the coins and networks SnapEX Pay works with now: asset_id (the code other tools take), symbol, network, decimals, price_usd, payment (can be received), payout (can be paid out) and payout_min_usd. No key needed. Call it before creating invoices, payouts or conversions to pick valid asset codes. | Read-only |
| list_conversions | Conversions of the account, newest first. Paginated with cursor. | Read-only |
| list_invoices | Invoices of the account, newest first, optionally filtered by status and environment. Paginated with cursor. | Read-only |
| list_payments | Payments of the account, newest first, optionally filtered by status. Paginated with cursor. | Read-only |
| list_payouts | Payouts of the account, newest first, optionally filtered by status. Paginated with cursor. | Read-only |
| list_static_address_deposits | Transfers received on one permanent address with their status and credited USDT. Paginated with cursor. | Read-only |
| list_static_address_networks | Lists the coins/networks for which you can get a permanent deposit address (create_static_address): asset code (e.g. "usdt.trc20", "usdc.polygon", "btc"), symbol, network, available, and how a deposit is credited (always in USDT). No key needed. | Read-only |
| list_static_addresses | Permanent deposit addresses of the account, optionally for one customer_ref. Paginated with cursor. | Read-only |
| list_transactions | Ledger of the balance, newest first: every credit and debit (payments, payouts, fees, conversions) with amount, direction and time. Paginated with cursor. | Read-only |
| list_webhooks | Webhook endpoints of the account: endpoint_id, url, events, status. | Read-only |
| preview_conversion | Step 1 of converting assets held on the account into USDT. The balance is kept in USDT (every payment is credited in USDT), so this matters only for an account that still holds another asset; to exchange USDT into another coin, send a payout in that coin (preview_payout, e.g. to your own address). mode "single": convert amount of from_asset_id (to USDT, or to to_asset_id); mode "all_to_usdt": convert every non-USDT holding to USDT. Returns preview_id with the amounts and expires_at; nothing moves yet. Then create_conversion. | Changes data |
| preview_payment | Low-level alternative to invoices: quotes a payment of an exact amount in one coin and how much USDT you will be credited. Returns credit_lock_id for create_payment (valid until expires_at). Most agents should use create_invoice instead. | Changes data |
| preview_payout | Step 1 of sending money. Quotes a payout of amount USDT from your balance to an address in any coin with payout=true in list_assets: returns preview_id, to_amount (what the recipient gets), fee and expires_at. Nothing is sent yet and the quote is free; check the address and amounts, then call create_payout with preview_id before expires_at. An invalid address answers invalid_address. | Changes data |
| rotate_webhook_secret | Issues a new signing secret for an endpoint (shown once); the old one stops working at once. | Destructive |
| select_invoice_payment_method | Chooses the coin for an invoice and returns the deposit address and exact amount to send (in the invoice payment attempt) — use it when you pass the address to the payer yourself instead of pay_url. | Changes data |
| update_webhook | Replaces the url and events of an endpoint, or disables/enables it (status). | Changes data |
