API Reference

Reference for every X114 API endpoint: auth, request schema, response schema, and a working curl example.

Base URL

All endpoints live under the same base URL. Use HTTPS in production.

https://x114.org/api/v1

Every request needs a Bearer token. Create one in Settings → API keys after signing up.

Authorization: Bearer sk_xxxxxxxxxxxxxxxxxxxxxxxx

Every call costs 1 credit. Insufficient balance returns 402. Credits never expire on the lifetime plan.

The same shape is used for every endpoint.

Code	Meaning
401	Missing or invalid API key.
402	Insufficient credits — top up from your dashboard.
429	Rate limit exceeded — back off and retry.
500	Server error — safe to retry with backoff.
