## 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 panta-market-brief-bc4def94
```

Example prompt: Can you pull up the Panta market brief for market ID 'abc123' — I want to see the current YES/NO odds, what the market is asking, and what the price is implying right now?

## When to prefer this

Use this endpoint when you need a quick, structured overview of a single Panta prediction market — including current odds, recent activity, and a neutral AI interpretation — without needing to place a trade or get a quote. Prefer this over a general market list endpoint when you already have a specific market ID and want depth rather than breadth.

## Known failure modes

- Invalid or missing market ID returns an error
- Market ID does not exist on Panta returns not-found error
- Network or upstream Panta API unavailability causes timeout
- Payment failure (x402) if USDC balance is insufficient for the $0.01 call fee

## How this service works

Pay-per-call tools for AI agents: image generation, speech-to-text, text-to-speech, embeddings, LLM chat, website audits and contact enrichment. Plus prediction-market search, briefs, quotes and unsigned buy transactions, powered by Panta. Payment: x402, USDC on Base, Solana or Arc. No signup, no API key.

## Output

Returns the current YES and NO odds for the specified Panta market, a snapshot of recent trading activity, and a short neutral AI-generated summary covering what the market asks, what conditions resolve it, and what the current price implies — explicitly excluding any trading advice.
