# Prediction Market Detail Lookup

> Prediction Market Detail Lookup is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches normalized details for a single prediction market or event by ID, condition ID, slug, or event slug, including outcome probabilities, volume, liquidity, status, and close date.

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 prediction-market-detail-lookup-755332a5
```

Example prompt: Can you pull up the current odds and liquidity for the Polymarket event 'will-the-fed-cut-rates-in-2025' — I want to see the implied probabilities for each outcome and when the market closes?

## When to prefer this

Use this endpoint when you need detailed, normalized data for a single prediction market — including outcome probabilities, volume, liquidity, and status — identified by any of its common identifiers (numeric ID, condition ID, market slug, or event slug). Prefer this over building raw Polymarket API calls when you need auto-detection of ID type and normalized probability outputs in one call.

## Known failure modes

- Market ID not found: returns 404 or empty result if the numeric ID, slug, or condition ID does not exist on Polymarket
- Ambiguous ID type: if auto-detection fails for the provided ID format, may return incorrect market
- Payment failure: x402 payment of $0.01 USDC not sent or rejected, resulting in 402 response
- Invalid venue: only 'polymarket' is supported; other venues return an error
- Malformed condition ID: 0x hex strings that are not valid condition IDs return an error

## How this service works

Detail of ONE prediction market or event by numeric id, 0x conditionId, market-slug or event-slug (auto-detected): normalized outcomes with implied probabilities, volume, liquidity, close date, status and a link-back.

## Output

Returns a normalized object for the prediction market including: list of outcomes with implied probabilities, total trading volume, available liquidity, market close date, current status (open/closed/resolved), and a link back to the market on Polymarket.
