## 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 fomoscan-wallet-lookup-722d8cde
```

Example prompt: Look up the FOMO trader behind the Solana wallet address 498g1rVnFcnjBjpfw1xyqA1WvgQXUU8RWuELjxkjAayQ — I only have the wallet, not their handle or user ID.

## When to prefer this

Use this endpoint only when you have a raw on-chain wallet address (Solana or 0x-prefixed EVM) and no FOMO handle or user id. If you already have a handle, prefer the handle-lookup endpoint ($0.10) and if you have a user id, prefer the user-id endpoint — both are cheaper. This endpoint costs $2.00 and is the right choice specifically when bridging on-chain identity to FOMO social identity.

## Known failure modes

- Wallet address not found or not linked to any FOMO account — returns 404 or empty result
- EVM address submitted without 0x prefix — may return error or no match
- Invalid or malformed wallet address format — returns validation error
- Address is valid but trader has no FOMO account — no result returned
- Rate limiting or payment failure for x402 micropayment — returns 402 or 429

## How this service works

Resolve a FOMO trader by verified Solana or 0x-prefixed EVM wallet. Use only when you have an on-chain address and neither handle nor user id — $2.00 vs $0.10 for those. Same User profile. EVM addresses must include 0x.

## Output

Returns a FOMO User profile object for the trader associated with the given wallet address, including their stable user id, handle, and other profile fields — the same User object returned by handle or user-id lookups.
