## 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-deepbluebase-xyz-9cff159d
```

Example prompt: What are the current 5-minute Polymarket prediction markets for BTC and ETH — give me the up/down odds, token IDs, and whether they're still accepting orders for this epoch.

## When to prefer this

Use this endpoint when you need to programmatically discover currently active 5-minute BTC/ETH/SOL Polymarket prediction markets with real-time odds and token IDs for automated trading, arbitrage, or market monitoring. Prefer this over the broader Polymarket intelligence feed when you specifically need short-duration epoch markets with token IDs ready for order placement.

## Known failure modes

- No active markets for current epoch — markets may be between epochs or Polymarket Gamma API is temporarily unavailable
- Stale data if the upstream Polymarket feed is delayed — epoch timestamps should be checked for freshness
- HTTP 402 if payment header is missing or USDC balance is insufficient
- Partial response if only some coins have active markets (e.g. SOL missing but BTC/ETH present)
- Empty markets object if Polymarket has paused 5-minute epoch markets

## How this service works

5-minute epoch prediction market discovery — active BTC/ETH markets with current odds and timing

## Output

Returns a structured object with active 5-minute prediction markets for BTC, ETH, and SOL, each containing: the market question text, current up and down prices (as probabilities 0–1), Polymarket token IDs for both sides, the target epoch UNIX timestamp, the market slug, and a boolean indicating whether the market is currently accepting orders.
