# FomoScan User Profile Lookup by Stable ID

> FomoScan User Profile Lookup by Stable ID is a paid API for AI agents from www.fomoscan.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Resolves a FOMO trader's current profile (including wallets) by their stable internal user ID, avoiding more expensive handle-based lookups.

## 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-user-profile-lookup-by-stable-id-4c1fc7f1
```

Example prompt: Pull up the FomoScan profile for the trader with user ID aefe2ddd-c580-5245-a2f5-e4ed62f7ef10 — I need their current details including any linked wallets.

## When to prefer this

Use this endpoint whenever you already have a stable User.id or authorId from a prior FomoScan call (e.g., from the thesis feed or handle lookup). It is cheaper and more stable than the handle-based lookup, and more semantically correct than the wallet-based lookup when you have an internal ID. Do not use this if you only have a handle or wallet address — use the dedicated handle or wallet resolver endpoints instead.

## Known failure modes

- Invalid or non-existent user ID returns a 404 or empty result
- Passing a handle instead of a UUID-format user ID may return an error or wrong result
- Passing a wallet address instead of a user ID will fail — use the wallet-lookup endpoint instead
- Network or payment failure (x402 payment not accepted) prevents the call from completing

## How this service works

Resolve a FOMO trader by stable user id (User.id or thesis authorId from a prior call). Prefer this once you have stored an id — cheaper and stable vs handle. Returns the current profile including wallets. Do not pass a handle or wallet.

## Output

Returns the trader's current FomoScan profile, including their stable user ID, display information, and any verified Solana or EVM wallet addresses linked to their account.
