## 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 x402-ser-api-wtf-de59443d -d '<json body>'
```

Example prompt: Can you fetch me the SerWTF token ecosystem data using the x402 data endpoint? I want to query 'SerWTF token ecosystem data' and I'm happy to pay $5 USDC for the response.

## When to prefer this

Use this endpoint when you need data or insights specifically about the SerWTF token ecosystem and are willing to pay $5 USDC per query via the x402 payment protocol on the Base network. Prefer this when you are already integrated with x402 micropayment flows and need SerWTF-specific token data.

## Known failure modes

- No X-PAYMENT header provided — returns 402 with x402 payment instructions
- Insufficient payment amount — rejected with payment required error
- Invalid payment currency — request fails validation
- Query field missing — 400 bad request
- Payment timeout exceeded (max 300 seconds) — transaction failure

Access insightful data for mint

## Output

Returns a JSON object with a 'message' string field containing the requested data about the SerWTF token ecosystem. On payment failure, returns an x402 payment-required error with payment instructions including the USDC asset address, payTo wallet, network (Base), and max amount (5 USDC).
