Readiness findings

Warnings and fixes from the latest readiness report.

  1. Publish /.well-known/x402.json

    Expose a manifest with service metadata so agents and catalogs can discover paid endpoints. Reference

  2. Expose a real HTTP 402 payment challenge

    A paid endpoint should reply with HTTP 402 and a payment requirements header when called without payment. Reference

  3. Publish an OpenAPI schema

    OpenAPI lets agents understand request bodies, response shapes, and error states without guessing. Reference

  4. Add listing metadata for Bazaar-style catalogs

    Name, description, category, tags, owner URL, and contact fields make services usable in agent marketplaces. Reference

  5. Publish robots.txt

    A clear robots policy helps crawlers and agent indexes understand how the site wants to be accessed. Reference

This bundle is generated from provider-supplied public metadata and point-in-time observations. The provider must verify every field before publishing it to an external registry. It does not create Coinbase Bazaar placement or ranking.

Counts are observed HTTP requests, not unique people, verified agents, buyers, leads, purchases, ranking, or guaranteed traffic. Automated and repeat requests can increase these totals. Ontario stores only listing id, publication surface, broad actor class, status, and time. It does not store IP addresses, raw user agents, wallet identifiers, contacts, payment headers, or request bodies for this receipt.

Provider actions

Keep evidence useful, then add clearly labeled reach if needed.

0.10 USDC
Refresh this profile's readiness evidence

Refresh is recommended: Evidence is older than Ontario's 168-hour strict-payment freshness window. Payment cannot improve the grade or edit provider metadata.

Agent handoff: Validate listing_id lst_7951309cc420 with POST https://ontarioprotocol.com/api/x402/refresh-listing/validate. If validation returns ok and local policy allows 0.10 USDC on Base, call POST https://ontarioprotocol.com/api/x402/refresh-listing with {"listing_id":"lst_7951309cc420"}. Probe the 402 challenge before signing locally; never send wallet keys to Ontario.

Keep this profile maintained

Readiness evidence kept fresh automatically after the included window, five Bazaar buyer searches re-run weekly with the history shown above, and an optional webhook alert when the grade changes or the endpoint stops answering. Currently maintained until 2026-10-27.

Agent handoff: POST https://ontarioprotocol.com/api/x402/renew-listing {"listing_id": "lst_7951309cc420"} (validate free first at https://ontarioprotocol.com/api/x402/renew-listing/validate)

Review renewal API

Payment buys a fresh observation, not a better score, metadata edit, ranking, traffic, or strict-discovery eligibility.

Trust boundary

What this publication does and does not prove.

This profile proves that Ontario processed a paid provider submission and reports point-in-time observable readiness, Bazaar retrieval, and any attached MCP Registry or remote-contract evidence. Ontario is not Coinbase and the launch passport is not an official certification. It does not guarantee endpoint safety, service quality, traffic, ranking, purchases, settlement success, or future behavior.
