## 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-e1b71557
```

Example prompt: I have a wallet address — 0xD5938dc56E24350cA762557F0b6253f1B2d2f8cb — can you find out which FOMO trader profile is linked to it?

## When to prefer this

Use this endpoint only when you have an on-chain wallet address (Solana or 0x-prefixed EVM) and do NOT have the trader's FOMO handle or user ID. It costs $2.00 vs $0.10 for handle/user-ID lookups, so always prefer the cheaper alternatives when available. This is the right choice when starting from blockchain data (e.g. DEX trades, wallet analytics) and needing to cross-reference with FOMO social profiles.

## Known failure modes

- Wallet address not linked to any FOMO account — returns not found
- EVM address provided without 0x prefix — rejected or no match
- Invalid or malformed wallet address — bad request error
- Solana address confused with EVM format — no match returned
- Rate limiting or payment failure — access denied

## 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 matching the provided wallet address, including stable user ID, handle, and other trader profile data — identical to results from handle or user ID lookups but resolved via on-chain wallet verification.
