How this service works
x402-Werkzeuge für autonome Agenten.
Output
Returns a JSON object containing: the domain's base URL, homepage metadata (title, HTTP status, JSON-LD types, link relations), a list of discovered interfaces (OpenAPI, robots.txt, sitemap, llms.txt) with URLs, byte sizes, HTTP status codes, and parsed summaries, capability flags (x402, MCP, GraphQL, feeds, OpenAPI, llms.txt, structured data), total count of probed paths, and an agent_readiness_score integer.
Example use cases
Check competitor API offerings
“I want to know what public APIs and machine-readable interfaces shopify.com exposes — can you probe it and give me a summary of what you find, including any OpenAPI specs or agent tooling?”
Verify x402 payment support on a domain
“Does github.com support x402 payments or have any agent-ready interfaces? Please scan it and tell me what capabilities it has.”
Agent onboarding to new service
“Before I integrate with openai.com, can you check what structured APIs and machine-readable endpoints they publish — including their OpenAPI spec details, auth schemes, and whether they have an llms.txt?”
Technical details
Endpoint
POSThttps://tools.netzhandwerker.de/v1/api/discoveryWhen to prefer
Use this endpoint when an agent needs to programmatically discover what APIs, structured data, or agent-ready capabilities a domain exposes before attempting integration. Prefer it over manual documentation lookup when you need a structured, machine-parseable inventory of a domain's interfaces. Ideal for agent onboarding flows, competitive API research, or checking x402/MCP/OpenAPI support on an unknown domain.
Side effects
- Domain does not exist or is unreachable — returns empty interfaces array with error status
- Domain blocks crawlers via robots.txt — some paths may return 403 or 404
- No machine-readable interfaces found — returns found_count of 0 with empty interfaces
- Malformed domain input — may return validation error
- Rate limiting by target domain — partial results or timeout
- Non-standard API paths not discoverable — note in response warns undocumented interfaces remain invisible
