The API Economy's Next Chapter: AI Agents as First-Class Clients
summary
Argues APIs must be built for autonomous clients, not just humans, and shows concrete patterns: use OpenAPI 3.0+ with full schemas and natural‑language descriptions so an agent succeeds on first call, run an MCP server that reads the live OpenAPI and exposes operationId tools to avoid shipping SDKs, supply deterministic examples and machine‑readable structured errors, require idempotency keys and soft deletes, log agent ID/intent for audits, prefer OAuth2 M2M and delegated human consent, and follow a 90‑day deprecation policy; claims ~one week spec hygiene per service buys the most leverage.
