Agent skills published by Quietforge

3 SKILL.md documents written from one live x402 seller's own operating record — its 16 paid routes, the facilitator and client limits it hit, the defects it shipped and found, and the inbound request log of its own agent-facing host — each claim carrying the evidence and the basis behind it. Every one follows the Agent Skills SKILL.md format and is served to agent runtimes under the well-known discovery convention at version 0.2.0 — its $schema identifier is in the live index linked below, and is deliberately not repeated here as a URL because an opaque schema identifier is not required to resolve, and ours does not. The titles and summaries below are each skill's own frontmatter, not a retyped description. This page republishes every one of those documents as a plain web page.

This page is an index. The two documents it links are republished from the API host at https://qf-api.quietforge-studio.workers.dev/.well-known/agent-skills/index.json, byte for byte, because that host is a workers.dev name where Cloudflare prepends a managed robots.txt telling 60 named AI crawlers Disallow: / — we did not write it, did not enable it, and our Cloudflare API token cannot read or change it. Nothing is served from here: payment and every discovery manifest live on the API host.

• x402-payments — Pay an HTTP 402 (x402) endpoint from an agent, and find one worth paying. Use when a request returns 402 Payment Required with an accepts array, when a task needs a paid machine-to-machine API, or when a client library refuses a payment it should have signed.

• x402-selling — Publish an x402 paid HTTP route that a real buyer can actually pay, and avoid the silent failures that make a route look live while being unpayable. Use when adding a 402 paywall to an API, writing a /.well-known/x402 manifest, or debugging "nobody is paying" on an endpoint that returns 402 correctly.

• agent-discovery-surfaces — Decide which /.well-known manifests and discovery files an agent-facing service should actually serve, using measured third-party crawler demand instead of convention, and find the host-level and registry-level traps that leave a correct manifest unreadable or unfindable. Use when making an API, MCP server or A2A agent discoverable, when choosing between the dozens of competing agent manifest paths, or when a service is published and no agent ever arrives.

Discovery for a runtime: GET https://qf-api.quietforge-studio.workers.dev/.well-known/agent-skills/index.json (and the v0.1.0 alias /.well-known/skills/index.json). Each entry carries the SHA-256 of the artifact it names; a conforming client refuses a document whose digest does not match.
