# UseAPI.net — third-party API for popular AI services <small>Index generated: 2026-06-10 17:08 UTC</small> > UseAPI.net provides API access to leading AI models for video creation, image generation, music composition, speech synthesis, face swapping, and more — all through a single $15/month subscription. Each API connects your existing AI website account(s) to a fully-featured REST API at website subscription prices, significantly cheaper than official API rates. Multi-account configuration with automated load balancing is included. An active subscription to the underlying service (e.g. Midjourney, Runway, Kling) is required. ## Start here - [Model Matrix](https://useapi.net/model-matrix): **Canonical list of every model across every API** (video, image, music, speech, face swap, upscale, extend, effects).

Always check this first to find which API exposes a given model. - [Complete API spec](https://useapi.net/assets/aibot/all.txt): Single combined documentation file for all supported APIs (~4 MB). Feed this to your LLM for cross-service integrations. For smaller-context models, fetch only the per-service files listed below. - [General Q&A](https://useapi.net/assets/aibot/qa.txt): Cross-cutting tips (rate limiting, prompt moderation, common patterns). **WARNING**: items are general-purpose and may reference deprecated APIs, sunsetted services, or scenarios not applicable to a specific API — always cross-check against the relevant service-specific documentation before applying. ## Universal conventions **Authentication.** Every useapi.net request uses header `Authorization: Bearer <token>`. The token format is `user:<number>-<unique-string>` (e.g. `user:12345-abcdefghi`). **Use the complete string** — include the `user:` prefix and the alphanumeric suffix. Do not truncate to just the number. Do not URL-encode. A single token authorizes ev
