# minia2a.uk Polymarket Quote (poly-quote)

> minia2a.uk Polymarket Quote (poly-quote) is a paid API for AI agents from minia2a.uk, paid per call via x402, $0.1/call, status unknown (last checked 2026-11-01).

Fetches a normalized, aggregated Polymarket market quote — prices, bid/ask spread, order book depth, volume, liquidity, and open interest — from three upstream sources (Gamma, CLOB, Data API v2) in a single call.

## 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 minia2a-uk-polymarket-quote-poly-quote-df0268dc
```

Example prompt: Pull a full normalized Polymarket quote for the market slug 'will-the-fed-cut-rates-in-july' — I want the best bid/ask, spread, top 3 order book levels on each side, 24h volume, liquidity, open interest, and how stale the data is.

## When to prefer this

Choose this endpoint when you need a single, aggregated Polymarket market quote that spans price data, order book depth, and open interest from all three official Polymarket upstreams simultaneously — avoiding the need to call Gamma, CLOB, and Data API v2 separately and reconcile them yourself. Especially useful for agents that need staleness visibility (age_seconds) without building their own multi-source polling logic. Not suitable for placing orders.

## Known failure modes

- Invalid or unknown market slug returns an error — ensure the slug matches exactly as listed on Polymarket
- Invalid conditionId format (not a valid 0x… hex string) causes a parsing error
- Unknown token identifier for the specified market returns empty book data
- Upstream APIs (Gamma, CLOB, Data API v2) may be temporarily unavailable, resulting in partial or stale data
- Payment not provided or insufficient (requires 0.1 USDC via x402) results in a 402 Payment Required response
- High age_seconds value indicates one or more upstream sources are lagging

## How this service works

One normalized read of a Polymarket market across three upstreams — Gamma (outcome prices, best bid/ask, spread, 24h volume, liquidity, tick size), CLOB (the top three order-book levels on each side, correct end of the book) and Data API v2 (open interest). Returns age_seconds so staleness is visible, and never places orders. Pass `market` as a slug or 0x… conditionId; add `token` to pick a specific outcome's book.

## Output

Returns a single normalized JSON object combining data from three Polymarket upstreams: outcome prices, best bid/ask, spread, 24h volume, liquidity, tick size (from Gamma); top 3 order book levels on each side (from CLOB); open interest (from Data API v2); plus age_seconds indicating how stale the data is. No orders are placed.
