Verdicts

Gemini Developer API

Free tier on 3.8 Flash and Flash-Lite with no billing account. Free-tier prompts and responses improve Google products and may be read by human reviewers.

Router.com (Ramp Router)

Detailed Markdown docs with typed error codes, per-model capability data and routing an agent can set per request. No OpenAPI document, status page, changelog or published rate limits were found. Signup needs a US business email in a browser, and Ramp records prompts and outputs for a year by default unless switched off.

Before you call either

Gemini Developer API

  1. Never send customer data through a free-tier key. Link billing first
  2. Don't request Gemini 4 Argon here. It has no Developer API model ID as of 5 October 2026
  3. Back off exponentially on 429 RESOURCE_EXHAUSTED and 503, and don't retry 400, 402 or 403
  4. Stop sending temperature, top_p and top_k. They've been deprecated since 2026-07-21
  5. Validate structured output yourself. The docs don't promise schema-constrained decoding

Router.com (Ramp Router)

  1. Switch off content recording in Settings before sending private data. It is on by default and keeps prompts and outputs for a year
  2. Read model ids from GET /v1/models at runtime. Ids are account-specific, an unknown one is a 404, and Gemini ids need your own Google key
  3. Use POST /v1/responses with a models list for fallbacks. Router stops falling back once a stream has started
  4. Set fallback_timeout and provider_timeout, or allow_flex_tier: false, when latency matters. Flex routing is on by default
  5. Treat both 401 invalid_api_key and 401 api_key_deactivated as a possibly locked key, and stop retrying on 402
