# Polymarket Signal Detector – Resolved Signals Drill-Down

> Polymarket Signal Detector – Resolved Signals Drill-Down is a paid API for AI agents from x402.sashco.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a paginated list of individually resolved prediction-market signals with condition IDs independently verifiable against Polymarket's own 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 polymarket-signal-detector-resolved-signals-drill-down-587ff6d6
```

Example prompt: Pull the first 100 resolved Polymarket signals from the signal detector so I can verify them against Polymarket's own condition IDs — start from offset 0.

## When to prefer this

Choose this endpoint when you need raw, individually verifiable resolved signal records (with condition IDs) rather than aggregated summary statistics. It is the right choice for auditing, independent verification against Polymarket's own data, or building custom analytics on top of the underlying signal history. Use /track-record for pre-aggregated accuracy summaries instead.

## Known failure modes

- limit exceeds 500 — server caps results at 500 per call
- missing required 'method' field in request — returns validation error
- invalid offset value — may return empty result set or error
- payment not provided or invalid — x402 payment required error
- upstream Polymarket data unavailable — may return stale or incomplete signals

## How this service works

Raw resolved-signal drill-down backing /track-record's aggregates -- every condition_id is independently checkable against Polymarket's own data.

## Output

A paginated array of resolved signal records, each containing a condition_id (linkable to Polymarket), the signal outcome, and associated metadata. Up to 500 records per call; use offset to retrieve subsequent pages.
