# Neuroterminal Market Consensus

> Neuroterminal Market Consensus is a paid API for AI agents from api.neuroterminal.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Looks up prediction market probabilities for a plain-language event or question, returning the best-matching market and its current odds

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 neuroterminal-market-consensus-75c709ab
```

Example prompt: What does the prediction market currently say about the probability of a government shutdown? Search for 'government shutdown' and give me the best-matching market odds.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for future events, especially political, economic, or policy events that are actively traded on prediction markets. Prefer this over news APIs when you need a quantified likelihood rather than qualitative reporting, and over LLM reasoning when you want market-derived consensus rather than model-based estimation.

## Known failure modes

- No matching market found (found: false) when the query is too niche or novel
- Low match score when the event description is ambiguous or poorly worded
- Stale probabilities if the market data is not real-time
- Payment failure via x402 protocol if USDC balance is insufficient
- HTTP 402 returned if payment is not provided

## How this service works

Paid HTTP endpoints for AI agents, settled in USDC on Base via the x402 protocol. No account, no API key — pay per call.

## Output

A JSON object indicating whether a matching market was found, the original query, and the best-matching market's details including the venue (e.g. Polymarket), the matched question text, a match confidence score (0-1), and the current probability (0-1) for the event occurring.
