## 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 aisa-mpp-data-apis-polymarket-public-profile-lookup-e90f374f
```

Example prompt: Can you look up the Polymarket public profile for the wallet address 0x1234567890abcdef1234567890abcdef12345678 and tell me their display name, bio, and whether they have a verified badge?

## When to prefer this

Use this endpoint when you need to resolve a raw Ethereum wallet address into a human-readable Polymarket identity, including display names, social links, and verification status. Prefer this over general blockchain explorers when the user context is specifically Polymarket trading activity or profile enrichment.

## Known failure modes

- Address not found — wallet has no associated Polymarket profile, returns null fields
- Invalid address format — input doesn't match 0x + 40 hex chars pattern, returns validation error
- Unregistered wallet — address exists on-chain but never registered on Polymarket, empty or null profile
- Rate limit or payment failure — insufficient USDC balance for per-request fee
