## 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 api-seerium-xyz-ea66b5eb
```

Example prompt: Scan Polymarket right now and show me the top 5 ranked trading opportunities and 10 market snapshots — I want to see which prediction markets have the best signals and liquidity.

## When to prefer this

Use this endpoint when an agent needs a broad, ranked scan of Polymarket prediction markets with Seerium intelligence layered on top — ideal for discovering high-opportunity trades, monitoring market signals, or ingesting order book context without manually querying individual markets. Prefer over raw Polymarket APIs when you want pre-ranked, signal-enriched output ready for agent consumption.

## Known failure modes

- No liquid markets available — returns empty opportunities list
- Polymarket data feed delay — snapshots may be stale
- Invalid limitSnapshots or limitOpportunities values below minimum of 1 — schema validation error
- Payment not fulfilled (x402) — returns 402 Payment Required before data is served
- Rate limit exceeded — too many calls in a short window

## How this service works

Crypto and prediction market intelligence through x402.

## Output

Returns a structured payload containing Polymarket market snapshots (up to limitSnapshots), order book data, Seerium-generated trading signals with confidence scores, and a ranked list of prediction-market opportunities (up to limitOpportunities) filtered by liquidity, spread, and signal strength.
