The Keyless Public API lets you query crypto market data and onchain DEX data without creating an account or managing API keys. Useful for quick prototyping, open-source projects, and educational use.
No headers, no auth — just send a request.

​
Usage Guidelines & Terms

The Keyless Public API is designed for quick testing. When using these endpoints, keep the following guidelines in mind:
  • Production & Commercial Use: Keyless endpoints are not recommended for production environments due to shared IP rate limits and server-side variability. For production deployments, higher rate limits, access to exclusive data endpoints, and commercial licensing, please consider upgrading to a CoinGecko Paid API Plan.
  • Attribution Required: If you display data from CoinGecko or GeckoTerminal keyless endpoints in your application, website, or project, you are required to provide appropriate attribution. Refer to the Attribution Guide for display requirements and brand assets.
  • API Terms of Service: Usage of both CoinGecko and GeckoTerminal keyless endpoints is governed by the CoinGecko API Terms of Service.

​
Base URLs

The onchain base URL (api.geckoterminal.com) differs from the /onchain path used with keyed API plans. See GeckoTerminal DEX API for full endpoint docs.
Do NOT include x-cg-demo-api-key or x-cg-pro-api-key headers — they are not needed and will be ignored.

​
Rate Limits

All keyless requests share an IP-based rate pool:
  • CoinGecko endpoints: ~5 calls/min (dynamic, varies by server load)
  • GeckoTerminal endpoints: ~5 calls/min (dynamic, varies by server load)
If you hit a 429 Too Many Requests, back off exponentially before retrying.
Rate limits are significantly lower than any keyed plan. The keyless API is not suitable for production workloads, scheduled polling, or high-frequency updates.Upgrade to a paid plan for dedicated rate limits and higher credits.
