One endpoint in full, ready to implement: https://coldiq.com/marketplace/docs/endpoint?method=<get|post>&path=<path>&format=markdown 3. Complete OpenAPI 3 spec: https://coldiq.com/marketplace/docs/openapi.json Base URL: https://api.coldiq.com Auth: send `Authorization: Bearer $COLDIQ_API_KEY` on every request. Always send an identifying `User-Agent` header — default client agents can be blocked at the edge and get a bare 403. Rate limits: 120 requests/minute, 3000 requests/hour per key. Every call costs credits; 402 means the balance is empty.
