## 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 quantaflow-x402-api-gateway-birdeye-proxy-a54783d4 -d '<json body>'
```

Example prompt: Can you pull the current price and 24h trading volume for SOL/USDC from BirdEye — use the /defi/price path with a GET method?

## When to prefer this

Choose this endpoint when you need BirdEye DeFi/Solana market data and want to pay per-call via x402 USDC micropayments rather than managing a BirdEye API subscription key — ideal for agents making sporadic on-demand queries where a subscription would be wasteful

## Known failure modes

- Payment failure: insufficient USDC balance causes 402 Payment Required before the upstream call is made
- Invalid path: unrecognized BirdEye endpoint path returns upstream 404 or error
- Malformed query params: incorrect parameter names or types return BirdEye validation errors
- BirdEye API downtime: upstream service unavailable returns 502 or 503
- Rate limiting: excessive requests may trigger BirdEye upstream rate limits

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream BirdEye API response body is passed through after successful x402 micropayment verification — typically JSON containing token prices, volumes, liquidity metrics, OHLCV candles, or other DeFi market data depending on the path queried
