## 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 agentdiet-polymarket-odds-lookup-63a5e483
```

Example prompt: What are the current Polymarket odds on whether the Fed will cut rates this year? Pull the latest prediction market probabilities on that topic.

## When to prefer this

Use this endpoint when an agent needs real-time prediction market probabilities from Polymarket for a specific topic without building a direct Polymarket integration. Ideal for agents that need quick, distilled probability signals for decision-making around elections, financial events, regulatory outcomes, or geopolitical events. Prefer this over raw Polymarket APIs when you want pre-distilled, compressed output optimized for agent consumption and are already using the AgentDiet x402 payment infrastructure.

## Known failure modes

- Topic not found or no active Polymarket market for that query — returns empty or null data
- Invalid or missing 'input' object — returns 400-level error
- Payment not received or insufficient USDC balance — HTTP 402 returned
- Polymarket upstream unavailable — service may return error or stale data
- Ambiguous topic string with no matching market — returns empty result set

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a 'data' field containing the distilled Polymarket odds/probabilities for the queried topic, a 'status' field confirming success, and an 'roi_proof' object showing the compression ratio achieved (e.g. 91.4%), indicating how much raw market data was condensed.
