apidex

verified public-api directory · mcp server

Agents hallucinate APIs.
This directory shows receipts.

apidex gives your coding agent 829 public APIs it can trust: every base URL, auth scheme, free-tier limit, and example request was checked by two independent verifier agents, machine-tested for liveness, and audited across model families. The verification record ships with every entry.

how an entry earns its stamp

Five passes. No field ships unchecked.

01

Research

An agent with live web search fills a strict schema from the official docs — endpoints, auth, pricing, limits, a working curl example.

02

Machine checks

Scripts hit every base and docs URL. Dead links and schema violations get flagged before any model opines.

03

Double verification

Two independent agents re-research every entry — one docs-first, one adversarial — and issue per-field verdicts: confirm, incorrect, or unverifiable.

04

Adjudication

Disputed fields go to a third agent that must rule with cited sources. 1,789 corrections came out of this stage alone.

05

Cross-family checks

A second model family re-checks the work — auditing entries offline with live-web arbitration, and running independent verification passes of its own. 1,934 more corrections; 44 dead APIs caught and dropped across all stages.
