## 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 netintel-polymarket-market-intelligence-ab07fcd0
```

Example prompt: What are the current Polymarket odds for 'Will the U.S. invade Iran before 2027?' — pull the outcome probabilities, volume, and whether the market is still active using the slug 'will-the-us-invade-iran-before-2027'.

## When to prefer this

Choose this endpoint when you need real-time Polymarket prediction market data including outcome probabilities, volume, and resolution details without API keys or a Polymarket account. It is ideal for agents that need to incorporate crowd-sourced probability estimates into analysis or reporting. It accepts both numeric market IDs and human-readable slugs (or full Polymarket URLs), making it flexible for various input formats. Prefer this over scraping Polymarket directly or using general web search when you need structured, machine-readable probability data at low cost ($0.003 per call).

## Known failure modes

- Invalid or unknown market ID/slug returns an error — no charge is applied
- Passing a full Polymarket URL as slug is supported via slug_extracted_from_url finding
- If Polymarket upstream is unavailable, call fails with no charge
- Market with unparseable outcomes returns outcomes_unparseable in findings array
- Numeric-looking slug treated as ID — id_treated_as_slug finding is returned to warn caller

## How this service works

Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet).

NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.

## Output

Returns a JSON object with the market question, active/closed status, list of outcomes each with an implied probability (0–1 scale, e.g. 0.55 = 55% chance), lifetime and 24h trading volume in USD, liquidity in USD, start and end/resolution dates, market description including resolution criteria, the Polymarket URL, category tag, and a cache_age_seconds field indicating data freshness (cached up to 60 seconds per market).
