## 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-gateway-solana-pump-fun-api-61cc4a58 -d '<json body>'
```

Example prompt: Pull the latest token stats for a Pump.fun coin on Solana — use the path '/tokens/trending' with a GET method to get the top trending meme coins right now.

## When to prefer this

Use this endpoint when you need pay-per-call access to Pump.fun Solana meme coin data without a long-term API subscription, and when your agent stack supports the x402 micropayment protocol for automatic $0.01 USDC billing per request.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Invalid or unsupported API path returns upstream 404
- Upstream Pump.fun API unavailability causes 502 or timeout
- Malformed query parameters result in upstream 400 error
- Vercel cold-start latency may cause occasional timeouts
