# Keyless Public API

> Start testing CoinGecko data instantly — no API key, no sign-up

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.

```bash theme={null}
curl -X GET \
  "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin,ethereum,solana&vs_currencies=usd"
```

No headers, no auth — just send a request.

***

## Base URLs

| Data                                                                    | Base URL                               |
| ----------------------------------------------------------------------- | -------------------------------------- |
| **CoinGecko**<br />Prices, market data, trending, global stats          | `https://api.coingecko.com/api/v3`     |
| **GeckoTerminal (Onchain DEX)**<br />Pools, tokens, trades, OHLCV chart | `https://api.geckoterminal.com/api/v2` |

<Note>
  The onchain base URL (`api.geckoterminal.com`) differs from the `/onchain` path used with keyed API plans. See [GeckoTerminal DEX API](https://www.geckoterminal.com/dex-api) for full endpoint docs.
</Note>

<Warning>
  **Do NOT** include `x-cg-demo-api-key` or `x-cg-pro-api-key` headers — they are not needed and will be ignored.
</Warning>

***

## Rate Limits

All keyless requests share an IP-based rate pool:

* **CoinGecko endpoints:** \~10–30 calls/min (dynamic, varies by server load)
* **GeckoTerminal endpoints:** \~10 calls/min

If you hit a `429 Too Many Requests`, back off exponentially before retrying.

<Warning>
  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](https://www.coingecko.com/en/api/pricing) for dedicated rate limits and higher credits.
</Warning>
