# OrcaTrace Whale Calibration Table

> OrcaTrace Whale Calibration Table is a paid API for AI agents from api.orcatrace.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Returns per-wallet hold-to-resolution win rates by odds band, mirror/fade ROI, and follow/fade labels for tracked Polymarket whale wallets (minimum 30 resolved entries).

## 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 orcatrace-whale-calibration-table-23810f66
```

Example prompt: Pull up the OrcaTrace whale calibration table so I can see which Polymarket whale wallets are worth following or fading, along with their win rates by odds band and mirror/fade ROI.

## When to prefer this

Use this endpoint when you need the full calibrated statistical profile of all tracked whale wallets — specifically their win rates by odds band and mirror/fade ROI — rather than a single signal feed item. It is the authoritative source for evaluating whether whale annotations in the signal feed are trustworthy, and is preferable when doing bulk wallet analysis or building a follow/fade strategy.

## Known failure modes

- Payment not processed or refunded — service guarantees refund if data cannot be delivered
- No wallets meet the minimum 30 resolved entries threshold — empty or sparse table returned
- Network or upstream data unavailability causing a 503 or timeout
- Invalid or malformed request parameters causing a 400 error

## How this service works

Paid ($0.05 USDC via x402). Whale calibration table: per-wallet hold-to-resolution win rates by odds band, mirror/fade ROI, and follow/fade labels (min 30 resolved entries). The data behind the whale_entry annotations in the signal feed; the free proof is GET /v1/track-record. Settle-early with a guaranteed refund — if we charge you but cannot deliver, the payment is refunded.

## Output

A table of tracked whale wallets on Polymarket, each with hold-to-resolution win rates broken down by odds band, mirror ROI, fade ROI, and a follow/fade recommendation label — based on a minimum of 30 resolved entries per wallet. This is the underlying dataset that powers the whale_entry annotations in the OrcaTrace signal feed.
