OpenAI- and Anthropic-compatible API for leading AI models

>log in to commentHi everyone, I'm one of the makers of BoostRail. It's one OpenAI- and Anthropic-compatible API for text, image and video models from several labs, billed from one prepaid USD balance. Coding agents are the main use case: Claude Code runs over /v1/messages, Codex CLI over /v1/responses, and Cline, OpenCode, Continue and Aider work through the OpenAI-compatible endpoint. If a route fails before the response starts, the request moves to another route of the same model, never to a different one. Setup guides are at https://www.boostrail.com/coding/. Feedback is welcome.
BoostRail gives developers and businesses one API for text, image and video models from Anthropic, OpenAI, Google, DeepSeek and other labs. It works with the OpenAI and Anthropic SDKs unchanged: point the base URL at BoostRail, use one key, and pick a model by its id.
Each request runs on a checked route. If that route fails before the response starts, the request moves to another route of the same model — it never swaps in a different model. Usage is metered per token in USD against one prepaid balance, with prices published per model.
Teams that already hold provider accounts can bring their own keys (BYOK): those requests run on their own quota and contract prices, with platform routes as automatic fallback. The BYOK free plan includes 1,000,000 requests a month.

- SDK compatibility — Works unchanged with OpenAI and Anthropic SDKs in Python, Node.js, curl, etc.
- Cache-read pricing — When supported, cached inputs are billed at a lower cache-read price.
- Media generation — Image generation from $0.011 per image and video generation from $0.043 per second.
Use cases
- Run chat completions across Claude, GPT, Gemini, DeepSeek, and other models with a single API key.
- Generate images or video clips in an application without managing separate provider accounts.
- Build resilient AI agents that automatically fail over to alternate routes of the same model.
- Use your own provider keys for cost-controlled inference while retaining platform fallback.

BoostRail FAQ
How do I switch to BoostRail with my existing OpenAI code?+
Change the base_url to https://api.boostrail.com/v1 and use your BoostRail API key; the rest of the code stays the same.
What happens if a model route fails during a request?+
BoostRail automatically retries on another route of the same model before any tokens are streamed, ensuring the model does not change.
Can I use my own OpenAI or Anthropic keys?+
Yes, via the BYOK feature; your requests run on your own quota and fall back to platform routes if needed.
Is there a free tier to try BoostRail?+
New accounts receive $1 of trial credit valid for 7 days, and the BYOK free plan offers 1,000,000 requests per month without top-up.
How are image and video generations billed?+
Images are billed per generated image (e.g., $0.011 each) and videos are billed per second of output (e.g., $0.043 per second).
Do unused prepaid credits expire?+
Purchased credits do not expire as long as the account remains active; only promotional or trial credits may have an expiry.
