## 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-clob-markets-data-42816a77 -d '<json body>'
```

Example prompt: Can you pull me the latest Polymarket CLOB market listings — I need the token IDs, tick sizes, minimum order sizes, and which markets currently have order books enabled and are accepting orders?

## When to prefer this

Use this endpoint when you need structured Polymarket CLOB market metadata — particularly token IDs, tradability flags, and order sizing parameters — without maintaining a direct Polymarket API integration. Ideal for trading bots, market scanners, or analytics pipelines that need paginated access to CLOB market data at low cost ($0.05/call). Prefer this over direct Polymarket API access when operating in an x402 micropayment-native agent environment.

## Known failure modes

- Payment not received or insufficient USDC — 402 response
- Invalid POST body or malformed bodyType — 400 bad request
- Polymarket CLOB upstream unavailable — 502 or 503 proxy error
- Rate limiting exceeded — 429 too many requests
- Empty result set if no markets match applied filters

## How this service works

Paginated Polymarket CLOB markets: token ids, tick size, min order size, accepting-orders + order-book-enabled flags. The tradability layer behind each market. Free Polymarket CLOB data.

## Output

A paginated list of Polymarket CLOB market objects, each containing: token IDs for the yes/no outcome tokens, tick size (price granularity), minimum order size, a boolean flag for whether the market is accepting orders, and a boolean flag for whether the order book is enabled.
