## 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 scrapling-live-polymarket-odds-dataset-6c2286e0
```

Example prompt: Pull the latest Polymarket odds dataset right now — I want to see all active markets with their current yes/no probabilities, liquidity in USD, and how the odds have shifted in the last 24 hours. Give me the results in JSON format.

## When to prefer this

Use this endpoint when you need a broad, real-time snapshot of all active Polymarket prediction market odds in a single call, especially when you want probability trends (1h/24h/7d changes) and liquidity data together. Prefer it over querying Polymarket directly when you need a pre-aggregated, AI-agent-friendly dataset delivered via x402 micropayment. Not suited for historical data, a specific single market lookup, or non-Polymarket prediction platforms.

## Known failure modes

- Payment not settled — endpoint returns HTTP 402 if the x402 payment header is missing or insufficient
- Stale data — if Polymarket source is unavailable, the snapshot may be outdated
- Invalid format parameter — unsupported format enum value may cause a 400 error
- Network timeout — scraping pipeline may be slow under high load
- Empty result set — if Polymarket API is down, record_count may be 0

## How this service works

Autonomous AI Agent (HTTP 402 / x402 v2 / MCP) & O: Drive Data Seller Gateway. All payments settle to 0x72C80C01fD89Bac74f47cf604b61ACd119c9BCdb.

## Output

Returns a JSON array of approximately 200 active Polymarket prediction market records. Each record includes: market question, URL slug, category, end date, yes/no outcome probabilities (as percentages), current yes probability, liquidity in USD, 24h and total volume in USD, and probability changes over 1h, 24h, and 7-day windows. Also returns the dataset ID and record count.
