api record

Start with get_overview or knownfix://overview for the complete KnownFix map: 6 full free workflows, three browser-local tools and companion guides, 10 services, 11 premium skills/bundles and 40 error signatures. No account or API key is needed for public discovery.

For an exact error, use search_fixes first. 14 fixes are free in full; a free top match includes its complete body. Other matches include a free diagnosis and current signed Base USDC/exact-ETH offers. Obtain operator spending approval before payment; keep offers and proofs private. An honest miss stays empty; request_fix is an…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_services reads open 12h ago

    Compare all current KnownFix reviews, Verified Repo Fix and Microsite Launch. Returns complete scope, deliverables, prices, delivery targets and limitations. Services requiring scope approval or payment after verified delivery are manual: use their order page, not order_service. SaaS security requires explicit written testing authorization. Other services use private-ticket checkout only after operator spending approval and target authorization.

  • get_offer changes data open 15h ago

    Create or refresh a one-hour signed bearer offer for a chosen skill, bundle, audit, or fix. Do not call this after a paid search_fixes result or an unpaid get_fix/get_skill result because those responses already include both payment rails. Choose USDC for Base Pay or ETH for exact wei; with no product arguments, this returns the general settlement document.

  • list_merch reads open 15h ago

    Browse the KnownFix Merch Store. Returns fixed product ids, lines, formats, and privacy-safe tracked links to the human Fourthwall storefront. Fourthwall shows the current localized price, options, tax, shipping, and availability. This tool does not place an order or collect checkout data.

  • list_skills reads open 15h ago

    Compare premium skills and multi-fix bundles. Returns current ids, free outlines, provenance, formats, and exact prices while full bodies remain paid. Call get_skill with a chosen id for signed USDC and ETH checkout; use search_fixes for a single error.

  • search_fixes reads open 20h ago

    Use this first for an exact error or distinctive symptom. Returns up to three confident ranked matches. A free top match includes the full fix. A paid top match includes a free diagnosis, confidence and compatibility, dollar price, signed USDC/Base Pay and exact-ETH rails, and one pay-and-redeem action; do not call get_offer. Use list_catalog to browse, get_fix only with a known id or payment proof, and request_fix only after an honest miss.

  • audit_theme reads open 8h ago

    Run a read-only theme audit on a public HTTP(S) page, free in full. Fetches but never modifies the page, then checks inline style CSS for brace errors, token gaps, incomplete dark themes, missing body backgrounds, and WCAG body-text contrast. External stylesheets are counted but not fetched. Use audit_endpoint instead for MCP, CORS, discovery, and payment readiness.

  • check_submission reads open 8h ago

    Check the private submissionId returned by submit_fix. Returns only pending-review, accepted, declined, or cataloged state and, when cataloged, the stocked fix id. It never returns submitted text or contributor details and creates no side effects. Use get_fix with catalogId when cataloged; do not resubmit merely because review is pending.

  • get_overview open 8h ago

    One free overview of all KnownFix offerings: complete free-workflow resource URIs, three browser-local tools and their companion guides, catalog routes, premium outlines and service prices/scopes/ordering boundaries. No account, payment, signed offer or order creation. Use search_fixes first for an exact error; list_services for full engagement terms.

  • list_catalog reads open 20h ago

    Browse every stocked error signature, title, tag, confidence label, and free-sample flag without ranking or creating an offer. Use search_fixes instead when diagnosing a specific error; it returns the best match and any purchase-ready checkout.

  • report_checkout_blocker changes data unknown never probed

    Use only after a signed KnownFix checkout cannot proceed before a payment hash exists. Reports one closed-vocabulary blocker tied to the valid offer; at most one aggregate count is accepted per offer. No wallet address, token, transaction hash, query, or free-form text is published. Do not call after payment; redeem with get_fix, get_skill, or audit_endpoint instead.

  • request_fix changes data unknown never probed

    Ask for a fix this store does not have yet. If we already stock it (matched on either field) you get the id straight back and no ticket. Otherwise you get a ticket; when we stock THAT fix, check_request returns it to you FREE, once. A ticket only ever redeems a fix created after the request: fixes that already existed when you asked are not free, whatever the request said. No contact details are collected. Set publish: true ONLY if the text may appear on a public wanted board — never include secrets, tokens, internal hostnames, or file paths.

    Check a private ticket from request_fix. Returns pending, declined, not-eligible, redeemed, or the full fix free once an eligible new fix is stocked. This call may atomically consume the ticket's one-time delivery, so save the returned body. Use get_fix when you already have a catalog id; do not create another request while this ticket is pending.

  • check_service_order moves money unknown never probed

    Check a private service order by its svc_ ticket. With paymentTx and paymentOffer, atomically confirms exactly one matching Base payment and moves the order into review. Without payment fields, returns current status; once complete, it returns the private Markdown report and SHA-256 digest. Keep the ticket and signed offer private.

  • audit_endpoint moves money unknown never probed

    Readiness audit of any agent-facing URL: MCP handshake, CORS, discovery docs (llms.txt, mcp.json), and payment-offer behaviour. First call with url alone for the FREE grade and failing-check list. For the full findings and remediations, call get_offer with productType "audit" and productId "conformance-report", pay, then call audit_endpoint again with the same url plus paymentTx and paymentOffer.

After payment, call once more with the matching paymentTx and private paymentOffer for the complete SKILL.md or assembled bundle decision tree, fix bodies, verification commands, update guidance, and sources. Do not use this for individual fixes; call get_fix instead. Never pay again merely because an existing proof is pending or denied.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id b35b226dca9a2dc3.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b35b226dca9a2dc3/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/b35b226dca9a2dc3/badge.svg)](https://brick.blue/agent/b35b226dca9a2dc3?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
