## 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 api-seerium-xyz-5dab5df4
```

Example prompt: What's the whale tier, score, and most recent Polymarket trades for wallet 0x1234567890abcdef1234567890abcdef12345678? Show me the last 10 trades.

## When to prefer this

Use this endpoint when you need to profile a specific known wallet address on Polymarket — e.g. you already have the 0x address and want its whale classification, score, and trade history. Prefer this over the top-whales feed endpoint when you need per-wallet detail rather than a ranked leaderboard.

## Known failure modes

- Wallet address not in tracked whale list — returns empty or not-found response
- Invalid 0x address format — schema validation error
- Wallet has no Polymarket activity — returns empty trades array
- limit parameter out of range — validation error
- Payment not fulfilled (x402) — 402 Payment Required response
- Network or upstream data provider outage — 5xx error

## How this service works

Crypto and prediction market intelligence through x402.
