# OrcaTrace Polymarket Batch Signals Feed

> OrcaTrace Polymarket Batch Signals Feed is a paid API for AI agents from api.orcatrace.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Returns a batch of up to 20 quality-gated Polymarket signal items (movers, whale entries, predetermined signals) with order-book microstructure and whale calibration data.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-polymarket-batch-signals-feed-484613a6
```

Example prompt: Pull up to 20 new Polymarket signals since feed index 150 — I want both movers and whale entries so I can see what big traders are doing and which markets are repricing.

## When to prefer this

Use this endpoint when you need to fetch multiple Polymarket signals in a single call (up to 20) rather than one at a time, reducing per-item cost and round trips. Prefer this over the single-item endpoint when building dashboards, running batch analysis, or polling for all new activity since a last-seen index. Use the type filter to focus on a specific signal category (movers, whale entries, or predetermined signals).

## Known failure modes

- Invalid 'type' filter value returns an error (must be mover, whale_entry, or predetermined)
- 'count' out of range (must be 1-20) returns validation error
- 'since' index value beyond current feed end returns empty result set
- Payment failure (insufficient USDC balance or x402 misconfiguration) returns 402 — no charge applied on error
- Network timeout if the feed computation takes longer than expected

## How this service works

Paid ($0.03 USDC via x402). Batch Polymarket feed items (up to 20): quality-gated movers + order-book microstructure, whale entries with calibration, predetermined signals. Poll GET /v1/index (free), then ?since=N for new items; filter with &type=mover|whale_entry|predetermined. Compute-first / settle-after — you are never charged for an error.

## Output

A batch of up to 20 Polymarket signal objects (filtered by type if specified), each containing quality-gated mover data with order-book microstructure, whale entry details with hold-to-resolution calibration scores, or predetermined signals. Items are indexed so the caller can track position for subsequent polls.
