# Crypto Derivatives Exchanges Liquidity Data (CoinGecko via x402)

> Crypto Derivatives Exchanges Liquidity Data (CoinGecko via x402) is a paid API for AI agents from x402-data-api.sigrunner.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-20).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability crypto-derivatives-exchanges-liquidity-data-coingecko-via-x402-5050a27d
```

Example prompt: Show me the top crypto derivatives exchanges ranked by open interest — I want to see BTC open interest, 24h volume, and how many perp and futures pairs each venue has.

## When to prefer this

Use this endpoint when an agent needs a quick, no-parameter snapshot of top derivatives exchange liquidity metrics (open interest, volume, pair counts) sourced from CoinGecko. Prefer it over general market cap endpoints when the task specifically concerns futures/perpetuals venues rather than spot markets. It covers centralized derivatives exchanges; for on-chain DEX perp data, a different source would be needed.

## Known failure modes

- Payment not included or malformed — 402 response requiring x402 USDC payment
- CoinGecko upstream unavailable — may return 503 or stale data
- Empty or partial exchange list if CoinGecko data is temporarily incomplete
- Network timeout from Cloudflare Worker if upstream latency spikes

## How this service works

Top crypto derivatives exchanges (CoinGecko): open interest BTC, 24h volume BTC, perpetual and futures pair counts, year established. No params. Use when an agent needs perp/futures venue liquidity data.

## Output

A JSON array of top derivatives exchanges, each with fields including exchange name, open interest in BTC, 24h volume in BTC, number of perpetual pairs, number of futures pairs, and year the exchange was established. Data is sourced from CoinGecko.
