## 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 geld-machen-phantom-allowlist-3f4a5f21 -d '<json body>'
```

Example prompt: Give me a list of up to 15 trusted sellers from the Phantom x402 allowlist so I can see which vendors are approved to use.

## When to prefer this

Use this endpoint when you need a pre-curated, trusted set of x402 sellers or endpoints from the Phantom marketplace rather than discovering arbitrary endpoints yourself. Ideal for agents that need a vetted shortlist of vendors before making micropayments.

## Known failure modes

- limit out of range (must be 1-40) returns validation error
- service unavailable on fly.dev returns 5xx
- empty allowlist if no sellers are currently indexed
- payment of $0.03 USDC required via x402 protocol or returns 402
