Browse x402-paid endpoints with public readiness evidence, or test your own
endpoint free before publishing a 0.50 USDC launch passport. Third-party
endpoints enter strict /discover only while their evidence is ready and fresh.
Ontario Protocol provides readiness and trust signals based on observable endpoint behavior,
manifest metadata, payment challenge behavior, report history, and public evidence.
It does not guarantee endpoint safety, service quality, financial outcome, or future behavior.
Agents should still enforce budget, policy review, and independent verification before spending.

Publish your x402 API for agent discovery
0.50 USDC
List your paid API for agents with an Ontario provider profile and Bazaar Launch Passport: a live readiness scan, sanitized Coinbase indexing preflight, five-query buyer-intent audit, optional signed MCP + x402 procurement evidence, distribution bundle, HTML and JSON evidence, badge, 30 days of automatic freshness maintenance and conditional strict-discovery eligibility. Ontario is not Coinbase. The 0.50 USDC fee buys processing and evidence, not Bazaar placement, ranking, traffic or purchases.

Publish an x402 Bazaar Launch Passport after free preflight
Start with the free, non-publishing preflight at /api/x402/list-service/request
or the full Bazaar buyer-intent audit. When the evidence is useful,
POST to /api/x402/list-service with a 0.50 USDC payment after
probing the challenge. The paid result includes a canonical profile, readiness report, sanitized Coinbase
indexing snapshot, five-query retrieval audit, badge, copy-ready distribution bundle, and 30 days of automatic
freshness maintenance. Ready services appear here, in /discover,
and in Ontario’s machine-readable manifests (for example /.well-known/x402.json)
when their stored report grades ready. Every paid submission also receives a canonical profile URL,
a JSON twin, and an embeddable badge even when readiness work remains. If the same endpoint and method already
has an older preview record, the paid profile becomes the single buyer-facing catalog record instead of creating
a duplicate. This canonicalization does not improve its readiness grade, Bazaar state, or ranking.
See the docs for the full payload shape, plus the
list-service JSON Schema,
the service listing quickstart,
/discover listing checklist and the
pending → ready remediation playbook.
Providers with a public MCP Registry record or remote can also add the optional
Agent Tool Procurement Passport, which binds read-only MCP
identity and tool-contract observations to the same x402 and Bazaar evidence profile.
The 0.50 USDC fee is for evidence processing and public launch-profile publication. Ontario is not Coinbase,
and the launch passport is not an official Bazaar certification. It does not promise placement, traffic,
a ready grade, a ranking, or an agent purchase.
Free payload validation (no payment; does not store a listing): POST /api/x402/list-service/validate.
Free launch preflight (compatibility route; stores no listing): POST /api/x402/list-service/request.
Sandbox rehearsal (no spend; does not store a listing): POST /sandbox/api/x402/list-service.
This endpoint still returns HTTP 402 first so you can test your x402 client integration end-to-end.
Validate a launch payload before payment
Paste your public JSON body here to validate it without publishing. Add buyer_query to name the
real task paying agents should retrieve. The free check runs a live readiness scan and a Bazaar lookup and lists the top fixes. A completed scan saves a public signed readiness report for the endpoint; verify_now: false skips the scan and the report.
Launch passport checkout is ready
0.50 USDC on Base publishes the evidence profile, optional signed MCP + x402 procurement evidence, and 30 days of automatic freshness maintenance.
Preparing the challenge does not sign or spend. A wallet-enabled x402 client must inspect policy and sign locally.
What happens after you submit
- The free request validates and optionally verifies the endpoint and stores no listing; an opted-in scan saves a public signed readiness report.
- A paid submission receives a canonical public profile, Bazaar audit, JSON evidence URL, distribution bundle, and linked badge without exposing submitted contact or payment-reference data.
- A paid profile supersedes an older free preview for the same endpoint and method in public catalogs; raw records remain available internally for settlement and audit continuity.
- A paid submission that scores
close remains visible here, but stays out of strict /discover until a fresh report grades ready.
/listings can show pending entries; /discover is filtered to strong evidence (default: ready).- Fix issues using the report warnings, then re-run
/verify to store a fresh report.
- Status and pipeline health:
/api/listings/status.
- Full machine-readable directory, including close and pending services:
