DEPRECATED in favor of `POST /v1/discover/endpoints` (same pipeline, card response shape, larger page cap); kept for existing CLI/MCP callers and removed in a future release. ## OpenAPI ````yaml https://monid.ai/openapi.json post /v1/discover openapi: 3.1.0 info: title: Monid API version: 0.1.0 description: >- Agentic payment platform for data — agents discover and buy data on demand. Authenticated `/v1/*` routes accept a Monid API key or Clerk JWT as a Bearer token. All errors return `{ code, message }`.
