# MNEMOS Arbitrage Scan

> MNEMOS Arbitrage Scan is a paid API for AI agents from mnemos-agent.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Runs MNEMOS's autonomous arbitrage-detection engine and returns a decision with reasoning about whether to act or abstain on an arbitrage opportunity.

## 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 mnemos-arbitrage-scan-e541369f
```

Example prompt: Run the MNEMOS arbitrage scan right now and tell me whether the engine recommends acting or abstaining, and what its reasoning is.

## When to prefer this

Use this endpoint when you need a real-time autonomous arbitrage decision from the MNEMOS engine — specifically when you want an AI-native, paid, per-call scan that returns both a human-readable reason and a binary act/abstain signal. Prefer this over generic market data APIs when you need an opinionated autonomous decision rather than raw price feeds.

## Known failure modes

- Payment not accepted or x402 micropayment fails — endpoint returns 402 Payment Required
- Invalid or missing required parameters — may return 400 or an empty/malformed response
- Engine returns abstained:true with no actionable reason when market conditions are ambiguous
- Service unavailable on Render cold-start — may return 503 or timeout
- Rate limiting if multiple rapid calls are made without valid payment headers

## How this service works

MNEMOS autonomous decision/memory engine. Four /v1 capability operations are x402 v2 paid; health/status/dashboard/operator routes are not x402 paywalls.

## Output

Returns a JSON object with three fields: 'module' (always 'arb'), 'reason' (a live engine-generated explanation for the decision), and 'abstained' (boolean indicating whether the engine recommends holding off rather than acting on an arbitrage opportunity).
