## 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 openintel-find-candidate-wallets-for-token-balances-872ea6da -d '<json body>'
```

Example prompt: I need to find candidate wallet addresses that hold at least 1234.5 of token 0x22aF33FE49fD1Fa80c7149773dDe5890D3c76F3b and 2.1 of token 0x4200000000000000000000000000000000000006 — can you search OpenIntel for wallets matching both of those balances?

## When to prefer this

Use this endpoint when you need to discover which blockchain wallet addresses hold specific token balances, especially when matching against multiple tokens using k-of-n logic. Prefer this over generic blockchain explorers when you need scored, ranked candidate wallets rather than exact lookups. Ideal for on-chain intelligence tasks like identifying holders of a specific token portfolio.

## Known failure modes

- No matching wallets found for the given criteria — empty results array
- Invalid token address format causes a 400 bad request
- Insufficient USDC balance for the $0.05 per-call fee results in payment failure
- Rate limiting or upstream OpenIntel API unavailability causes 5xx errors
- Stale cache data may cause slightly outdated balance information (cache_age_seconds > 0)

## How this service works

Pay-per-call proxy for the OpenIntel API.

## Output

Returns a list of candidate wallet addresses, each with a relevance score (0–1), k-of-n match details indicating how many of the specified token criteria were satisfied, the specific matching token balances found, and a timestamp indicating data freshness.
