## 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-volume-analytics-7cd55f74 -d '<json body>'
```

Example prompt: Pull the volume analytics for Polymarket prediction markets and show me which markets have the most trading activity right now.

## When to prefer this

Choose this endpoint when you need programmatic access to Polymarket volume and trading activity data without building a direct Polymarket API integration. Ideal for AI agents that need pay-per-call access to prediction market analytics without managing API keys or subscriptions. Prefer this over direct Polymarket API access when operating in an x402 micropayment context.

## Known failure modes

- Polymarket Gamma API unavailable or rate-limited — may return empty markets array
- Invalid or unsupported filter parameters resulting in empty result set
- Payment failure via x402 protocol — call not executed
- Stale or delayed data if Polymarket API has indexing lag

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns a JSON object sourced from the Polymarket Gamma API containing a list of markets with associated volume and trading activity metrics, including market identifiers, volume figures, and related analytics data.
