OpenRouter API: check the terms before you connect.

ChinaGenAI is an independent guide and is not affiliated with OpenRouter. We do not issue this provider’s official API credentials.

Before the first request

1. Open the provider’s API documentation and billing page. Confirm your region, model ID, access eligibility and current quota.
2. Create a key in your own provider account. Keep it out of browser bundles, shared screenshots and public repositories.
3. Use the documented API base URL. A consumer chat URL is not an API endpoint.
4. Start with a short input and a small output limit. Check the response and account usage before automating a batch.

Use one task to check the integration

For a supplier quote, extract quantity, currency, unit price, MOQ and missing terms. The request builder and JSON checker give you a fictional input and a field checklist. A syntactically valid response still needs source verification.

What is available on this site?

Guides, request building and JSON checking are free to use without an account. Site-provided inference is a separate service. Check free API access and limits for its actual status.

Checked 18 October 2026. Provider terms may change; no inference benchmark or availability guarantee is implied.
