## 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

Example prompt: Search Polymarket for prediction markets about the 2024 US presidential election and show me the current outcome probabilities — return up to 10 markets.

## When to prefer this

Use this endpoint when an agent needs real-time prediction market probability data from Polymarket for any event, topic, or question. Prefer this over general news or sentiment APIs when the user explicitly wants crowd-sourced probability estimates or market-implied odds. Ideal for research agents, trading assistants, or any workflow that needs quantified uncertainty about future events.

## Known failure modes

- No markets found for the query — returns empty results list
- Query string is missing — returns validation error requiring 'q' parameter
- Limit out of range (outside 1-20) — may return error or default behavior
- Polymarket API unavailable — upstream service error propagated
- Payment not completed — x402 payment required error before data is returned

## How this service works

Polymarket odds search: prediction market questions and outcome prices for a query. Use when an agent needs prediction-market probability data.

## Output

A list of up to 20 Polymarket prediction market questions matching the search query, each with associated outcome options and their current probability prices (as decimals or percentages), reflecting the crowd-sourced market consensus on the likelihood of each outcome.
