Tools
| Tool | Description | Behaviour |
|---|---|---|
| agent_can_pay | Free pre-payment policy decision. Agents ask whether an x402 endpoint should be paid under strict, standard, or permissive policy. The free result is sufficient by default; set require_audit_receipt only when a settlement-backed receipt is required. | Read-only |
| agent_trust_preview | Free live, rate-limited agent trust preview for one public endpoint. Returns safe signals and issues without the paid evidence bundle or attestation; use the paid trust scan only when the preview is insufficient. | Read-only |
| bazaar_buyer_intent_gap | Free read-only provider audit that runs Coinbase's indexing preflight and measures one public x402 endpoint across five live CDP Bazaar buyer-search variations. Returns retrieval coverage, observed sample ranks, alternatives, public 30-day call and unique-payer observations, Base USDC price bands, HTTP 402 and metadata readiness, and the activation boundary. Public quality counts may include owner-funded calls and are not revenue. It never signs or settles. | Read-only |
| find_x402_tool | Free buyer-side search across Ontario's fresh strict-ready paid profiles, Agentic Market, and Coinbase CDP Bazaar. Rank public, credential-free endpoint candidates by task relevance plus bounded source-reported recent activity, with optional Base/USDC budget filtering. Paid Ontario publication adds no ranking score. This is discovery, not a safety certification; run readiness and can-pay before spending. When the query is provider-side publication intent, skip buyer marketplace search and return the free listing validator followed by the gated 2.00 USDC publication workflow. | Read-only |
| github_x402_repo_scan | Free pre-deployment scan of one public GitHub repository for x402 implementation, HTTP 402 tests, payment configuration, buyer documentation, discovery metadata, CI gates, and sensitive filenames. Returns paths and remediation, never source contents. | Read-only |
| ontario_agent-pay-query-v2 | Verify an x402 endpoint before an AI agent pays: get ALLOW or DENY with reasons, a readiness score, report ID and a settlement-backed SHA-256 evidence receipt. This x402 paid API verification service probes the HTTP 402 challenge, payTo, price, Base USDC network and asset, manifest freshness, budget and spend policy. Run free can-pay and readiness checks first. Readiness evidence is not a safety guarantee. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.002 USDC is inside the agent budget. [PAID: 0.002 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_agent-trust-scan | Use when an agent needs a structured trust report for a public agent card or A2A endpoint before routing money or user work to it. This is a paid point-in-time scan, not an endpoint-readiness check. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.01 USDC is inside the agent budget. [PAID: 0.01 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_list-agent | Use only when the caller owns the agent and wants to submit a public directory listing. Validate the payload for free first; payment does not guarantee approval, traffic, ranking, or safety. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.10 USDC is inside the agent budget. [PAID: 0.10 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_list-service | Publish a provider-owned x402 API so AI agents can discover and buy it. After free validation and a Bazaar buyer-intent audit, the 2.00 USDC Launch Passport creates a signed public HTML/JSON profile, readiness and Coinbase indexing evidence, a five-query retrieval snapshot, badge, copy-ready MCP/catalog records, and 30 days of freshness maintenance. It can become eligible for strict Ontario discovery when evidence is ready and fresh. It does not guarantee Coinbase placement, ranking, traffic, purchases, a ready grade, or safety. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 2.00 USDC is inside the agent budget. [PAID: 2.00 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_purchase_router | Free deterministic pre-purchase routing across Ontario tools. Use this before any paid Ontario tool to decide whether the task is free-only, needs free preflight, or is eligible for a paid result after wallet, Base network, and explicit budget gates. Natural endpoint-verification tasks route to the free readiness verifier and disclose the optional 0.002 USDC settlement-backed receipt only when extra audit evidence is needed. Provider jobs such as publishing, registering, or making an x402 endpoint discoverable can route to the self-serve 2.00 USDC publication product after preflight. Existing paid profiles can route to the 0.10 USDC evidence refresh only after the free refresh validator. Empty calls return safe free discovery guidance instead of guessing a purchase. This tool never invokes another tool, signs a payload, or spends funds. | Read-only |
| ontario_refresh-listing | Use only for an existing paid Ontario provider profile when the caller wants a fresh live readiness observation attached to its canonical HTML, JSON twin, and badge. This tool cannot edit provider metadata, improve a grade by payment, or buy ranking or traffic. Do not pay while the launch passport's 30-day included maintenance is active. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.10 USDC is inside the agent budget. [PAID: 0.10 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_reputation | Use when an agent already has a stable agent identifier and needs the cheapest accumulated reputation lookup. Use Agent Trust Scan instead when there is no usable history or a fresh card scan is required. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.001 USDC is inside the agent budget. [PAID: 0.001 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_task_fit | Free task-to-tool matching with an optional Jev second opinion. With allow_typesafe=true, your public task and Ontario's public tool descriptions are sent to TypeSafe for Jev inference. Do not supply secrets, personal data, private URLs, or customer content. Ontario does not persist task text here. TypeSafe processing is subject to its policies; zero retention is not promised. Without consent, only Ontario's deterministic router is used. Returns a callable tool and input schema, or abstains. Never executes tools or authorizes payment. Model quota exhaustion falls back to deterministic routing. | Changes data |
| ontario_validate-agent | Validate an agent listing payload for free before publication. Never publishes, signs or spends. | Changes data |
| ontario_validate-refresh | Check an existing paid provider profile's refresh eligibility for free, including cooldown. Never refreshes, signs or spends. | Changes data |
| ontario_validate-service | Free provider listing preflight. Validate public service metadata before buying the 2.00 USDC Ontario launch passport. Returns field errors or a normalized request and publication decision. Set verify_now only to create a public readiness report. Never publishes a listing, signs or spends; a valid payload alone does not establish readiness or Bazaar placement. | Changes data |
| ontario_x402-demand-authenticity | Use when an agent, marketplace, provider, or investor needs to separate observable Base USDC settlement evidence from unsupported independent-demand claims. Detects direct self-payments, classifies disclosed related-party and unattributed receipts, measures payer concentration, and does not call unknown wallets customers. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.02 USDC is inside the agent budget. [PAID: 0.02 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| ontario_x402-implementation-audit | Use when a provider or developer needs a bounded, task-specific x402 code review for a public endpoint or GitHub repository. Returns payment, discovery, security, debugging, and launch findings without returning source contents or secret values. Agent payment guidance: run free can-pay and readiness checks first; pay only when policy allows base 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and 0.01 USDC is inside the agent budget. [PAID: 0.01 USDC via x402 on Base. Two-step flow: call without payment to receive MCP PaymentRequired, then retry with params._meta['x402/payment'] containing the signed PaymentPayload. The legacy _x402_payment base64 argument is also supported. Sign only after explicit budget and policy approval.] | Changes data |
| x402_launch_kit | Generate a validated listing payload, x402 resource draft, MCP descriptor, GitHub readiness workflow, README snippet, and registry copy for one paid endpoint. | Read-only |
| x402_readiness_verify | Free check for whether a paid endpoint is ready for agent discovery and x402 payment. Returns a free end-to-end buyer-path diagnostic handoff plus a grade-aware provider handoff: validate listing metadata free before any optional 2.00 USDC publication, and do not pay for publication while the endpoint is not ready-grade. | Changes data |
| x402_verification_reports | Public ledger of recent x402 readiness reports. | Read-only |
