Tools (19)

`audit_endpoint`	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. This tool both previews and redeems the paid report; no separate delivery tool is needed.
`audit_theme`read-only	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_request`	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`	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.
`check_submission`read-only	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_fix`	Get or redeem a fix after search_fixes or list_catalog identifies the id. Free samples return immediately. For a paid fix, call with the id alone to receive a free diagnosis preview, confidence and compatibility, dollar price, signed Base Pay USDC and exact-ETH offers, and one pay-and-redeem action; then call once more with the matching paymentTx and private paymentOffer. Never pay again merely because an existing proof is pending or denied.
`get_free_skill`read-only	Return the complete Markdown body of one free workflow listed by get_overview. No account, payment, paid body or private data. Use list_skills/get_skill for premium products instead. This tool supports clients that cannot read MCP resources.
`get_offer`read-only	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.
`get_overview`read-only	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.
`get_skill`	Get or redeem a premium skill or multi-fix bundle after choosing with list_skills. Call with the id alone to receive the free outline, dollar price, signed Base Pay USDC and exact-ETH offers, and one pay-and-redeem action. 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.
`list_catalog`read-only	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.
`list_merch`read-only	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_services`read-only	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.
`list_skills`read-only	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.
`order_service`	Create a private ticket and signed Base USDC/ETH checkout for an eligible automated service only. Do not call for requiresScopeApproval services (SaaS security, Microsite Launch) or paymentTiming:after-verified-delivery (Verified Repo Fix); these require manual scope approval via their published page. Accepts authorized public HTTPS targets only. Obtain operator spending approval. Never send credentials or confidential data. Keep the returned svc_ ticket private.
`report_checkout_blocker`	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`	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.
`search_fixes`read-only	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.
`submit_fix`	Offer a fix for the catalog. Submissions are reviewed by the operator before listing; include a reproduction so the fix can be verified rather than trusted. Returns a private submissionId; save it and call check_submission for pending, accepted, declined, or cataloged status. Submitted text and contributor details are never returned by the status tool. Revenue-sharing for accepted contributions is planned, not yet live.
