## 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-evm-fb945464
```

Example prompt: I have this EVM wallet address 0x04e4ba53f19b3e4deb4a78ca9543b7e92a228199 and I want to find out who this trader is on FOMO — can you look up their profile?

## When to prefer this

Use this endpoint only when you have an on-chain wallet address (EVM 0x-prefixed or Solana) and do NOT have the trader's FOMO handle or stable user ID. If you have either a handle or user ID, use those cheaper endpoints ($0.10) instead — this wallet lookup costs $2.00 per call. Prefer this when doing on-chain-first investigations where the social identity is unknown.

## Known failure modes

- Wallet address not verified or linked to any FOMO account — returns 404 or empty result
- EVM address provided without 0x prefix — rejected as invalid input
- Address belongs to a contract rather than a user wallet — no match found
- Rate limiting or payment failure — returns 402 or 429
- Malformed or invalid wallet address format — returns 400

## 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 whose verified wallet matches the provided address. The profile includes their stable user ID, public handle, and associated trader metadata — the same profile returned by handle or user-ID lookups, just resolved from an on-chain wallet.
