## 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-to-user-resolver-61bf623c
```

Example prompt: Can you find the FOMO trader profile linked to the Solana wallet 7tCETmedwBk4zFjmq7xcDo1vCMDTFNfDkobXyNj2grR3? I only have the wallet address, not their handle or user ID.

## When to prefer this

Use this endpoint exclusively when you have an on-chain wallet address (Solana or 0x-prefixed EVM) and do not have the user's FOMO handle or stable user ID. Note this costs $0.20 per call vs $0.10 for handle/ID lookups — so prefer those cheaper endpoints whenever a handle or user ID is already available.

## Known failure modes

- Wallet address not verified or not linked to any FOMO user — returns 404 or empty result
- EVM address missing the 0x prefix — will fail validation
- Malformed or invalid address format — returns error
- Address belongs to a contract rather than a user wallet — no match found
- Rate limiting or payment failure — 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 including the stable user ID, public handle, verified wallet addresses, and associated metadata — the same profile structure returned by handle-based or ID-based lookups.
