Machine-readable surfaces
OpenAPI, llms.txt, the MCP server card and the agent-skills index, for tools that read the API without a human.
| Surface | URL |
|---|---|
| OpenAPI 3.1 | /openapi.json |
| llms.txt | /llms.txt |
| llms-full.txt (docs and reference in one file) | /llms-full.txt |
| MCP server card | /.well-known/mcp/server-card.json |
| Agent skills index | /.well-known/agent-skills/index.json |
| API catalog (RFC 9727 linkset) | /.well-known/api-catalog |
| OAuth protected-resource metadata | mcp.instadata.dev/.well-known/oauth-protected-resource |
| Health | api.instadata.dev/healthz |
All of them are generated from the same registry the API runs on, so an endpoint appears here the day it serves and not before. Every HTML page also links them with rel attributes (service-desc, mcp-server, agent-skills, service-meta), and robots.txt welcomes AI crawlers.
