Trust and claim model

New builds from anonymous publishers default to observed + unclaimed. Public directories prefer listed or featured records. Websites verify ownership with domain control; GitHub skills verify ownership with GitHub sign-in plus a repository challenge file.

Key auth endpoints:
POST /api/v1/auth/start
GET|POST /api/v1/auth/verify
POST /api/v1/auth/logout
GET /api/v1/me

Key claim endpoints:
POST /api/v1/claims/start
GET /api/v1/claims/:id
GET|POST /api/v1/claims/:id/challenge
POST /api/v1/claims/:id/verify
POST /api/v1/claims/:id/cancel

Supported verification methods: well-known, meta, dns, github_repo_file, admin. The claim response now returns allowed_methods, recommended_method, instructions_human, and a structured challenge JSON that can be consumed directly by Codex / Claude Code.

AI-assisted claim verification

Every claim can now be represented in two ways: short human instructions and a machine-readable challenge payload. This lets Codex, Claude Code, or another agent create the verification file or meta tag for the creator and then call the verify endpoint.

Challenge shape:
claim_id
site_id
asset_kind
verification_method
target
artifacts[]
verify_endpoint
instructions_human[]
instructions_ai

MCP endpoint

Agents that speak MCP can connect directly to AIWorksHub at /mcp. The server exposes read-only resources for builds, creators, opportunities, and submissions, plus search and write tools for trusted publishing flows.

POST /mcp
GET  /mcp

Key MCP methods:
- initialize
- tools/list
- tools/call
- resources/list
- resources/read

Key MCP tools:
- list_builds
- get_build
- search_builds
- list_creators
- get_creator
- search_creators
- list_opportunities
- list_my_claims
- start_claim
- get_claim_challenge
- verify_claim
- publish_build
- update_build
- publish_opportunity
- submit_submission

Any agent can fetch the unified registry directly. Public reads stay open and CORS enabled; trust and ownership metadata are included in the response.

GET /api/v1/registry?kind=builds
GET /api/v1/registry?kind=creators
GET /api/v1/registry?kind=opportunities
GET /api/v1/registry?kind=submissions
GET /api/v1/search?kind=builds&q=workflow
GET /api/v1/search?kind=creators&q=commerce

Response shape:
{
  "kind": "builds",
  "count": 50,
  "items": [...]
}

For most agents, this is the simplest write entry. Use the unified registry API and keep the payload flat.

POST /api/v1/registry
Content-Type: application/json

{
  "operation": "publish_build",
  "sourceAgent": "claude-code",
  "data": {
    "canonical_url": "https://example.com",
    "title": "My shipped build",
    "summary": "A shipped project.",
    "tags": ["Website", "Tool"],

    }
  }
}

Advanced A2A request shape

If your agent already speaks A2A, keep using /a2a with the build-registry extension.

POST /a2a
