Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

agent_can_pay Read-only

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.

endpointstring, required

Public x402 endpoint to evaluate before payment; never include credentials or private query parameters.

max_usdcstring

Caller-approved per-call spending ceiling in decimal USDC, for example 0.01. This check never spends funds.

agent_policystring

Readiness policy to apply. Use strict unless the operator explicitly permits a different policy.

require_audit_receiptboolean

Explicitly request the optional paid receipt handoff after an allow decision. This does not submit payment.

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.

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 0.50 USDC publication workflow.

ontario_base-tx-check

Did this Base payment settle? Status, block, timestamp and confirmations for one transaction hash, with its ERC-20 Transfers decoded (token, from, to, amount; up to 100 listed, transfers_total gives the full count) and any EIP-3009 authorization used, plus match flags for an optional expected payTo and amount, so an x402 PAYMENT-RESPONSE can be checked.

Which x402 API should my agent call? Live API finder for any task. Required: task. Returns up to 5 paid APIs that answered a fresh unpaid probe with a valid Base USDC 402, ranked by task fit, price and Bazaar-reported repeat buyers, each with live price, network and a ready-to-call request.

ontario_list-agent

Use only when the caller owns the agent and wants to submit a public directory listing. Payload validation is free; payment does not guarantee approval, traffic, ranking, or safety. [PAID: 0.10 USDC via x402 on Base. Two-step flow: a call without payment returns MCP PaymentRequired; the retry carries the signed PaymentPayload in params._meta['x402/payment'].

Input schema (JSON)

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 0.50 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. [PAID: 0.50 USDC via x402 on Base. Two-step flow: a call without payment returns MCP PaymentRequired; the retry carries the signed PaymentPayload in params._meta['x402/payment']. The legacy _x402_payment base64 argument is also supported. Signing happens in the caller's wallet.]

Argument	Type	Description
name*	string	Public service name displayed on the provider profile.
tags	array	Public capability tags for discovery, up to ten relevant labels.
asset	string	Payment token contract accepted by the provider on the declared network.
method	string	HTTP method used to call the provider's endpoint.
source	string	Privacy-safe aggregate acquisition bucket; never a URL or query.
network	string	Provider payment network, for example base or eip155:8453. Ontario publication itself uses Base USDC.

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 0.50 USDC publication product after preflight. Paid reads it can recommend: ontario_find-api (a live-checked paid API for a task), ontario_base-balances (Base wallet balances), ontario_base-tx-check (whether a Base transaction settled) and ontario_base-gas (current Base gas prices). 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

Argument	Type	Description
task*	string	Public task description only; never include credentials or private customer data.
network	string	Wallet policy network; Ontario paid tools currently require Base mainnet.
max_usdc	any	Optional owner-authorized per-call USDC ceiling from 0 to 1000. Send a JSON number or decimal string such as 0.5, '0.50', '$0.50' or '0.50 USDC'. Omit when no budget is authorized; a budget is only a ceiling and does not grant spending authority. The router never increases it.
wallet_enabled

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. Freshness maintenance is automatic and included during the launch passport's first 30 days. [PAID: 0.10 USDC via x402 on Base. Two-step flow: a call without payment returns MCP PaymentRequired; the retry carries the signed PaymentPayload in params._meta['x402/payment']. The legacy _x402_payment base64 argument is also supported. Signing happens in the caller's wallet.]

Argument	Type	Description
listing_id*	string	Existing paid provider profile id.
_x402_payment	string	base64 x402 PaymentPayload (USDC on Base); obtain the requirements by calling this tool without it first.
paid_refresh_tx	string	One-use retry reference only when a settled refresh could not complete.

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.

Argument	Type	Description
task*	string	A public capability request, never private task content.
network	string	Network permitted by the caller's wallet policy; Ontario paid tools require Base mainnet (eip155:8453).
max_usdc	string	Explicit owner-approved USDC ceiling; never inferred.
allow_typesafe	boolean	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.
wallet_enabled	boolean	True only when the caller can locally sign an x402 payment; this flag does not authorize spending.
free_preflight_complete

ontario_validate-agent

Free provider listing preflight. Validate public service metadata before buying the 0.50 USDC Ontario launch passport. Returns field errors or a normalized request and publication decision.
