# x402 Market Intelligence Monitor

> x402 Market Intelligence Monitor is a paid API for AI agents from monitor.memoryapi.org, paid per call via x402, $0.005/call, not verified (last probed 2026-10-22); live alternatives: CDN Site Daily Traffic Stats (free) and AnyAPI SimilarWeb Traffic ($0.007).

Agents call it through Zero, which pays per call: no API key and no wallet of your own. New accounts start with $5.

## 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 monitor-memoryapi-org-b5b8fdf3
```

Example prompt: Give me a market intelligence snapshot of the x402 ecosystem — on-chain transaction history, how many agentic services exist broken down by category, and any current ecosystem trends.

## When to prefer this

Use this endpoint when you need a broad market overview of the x402 ecosystem including transaction history, category-level service counts, and trend data. Prefer this over sibling endpoints when you want on-chain transaction history alongside market categorization data, rather than just API activity stats or service listings alone.

## Known failure modes

- Service unavailable if monitor.memoryapi.org is down (5xx)
- Payment required error if x402 micropayment of $0.005 USDC is not provided (402)
- Empty or stale data if on-chain data source has not been recently indexed
- Rate limiting if too many requests are made in a short period

## Output

Returns on-chain x402 transaction history, service counts broken down by category from Agentic Market, and ecosystem trend data showing how the x402 micropayment protocol is growing and being used across agentic services.
