# GENESIS Agent Tools — URL Structure Check

> GENESIS Agent Tools — URL Structure Check is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Analyzes a URL's structure and path patterns to determine evidence quality, API compatibility, and agent-readiness signals.

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 genesis-agent-tools-url-structure-check-8cab777f -d '<json body>'
```

Example prompt: Can you check whether the URL https://api.example.com/v1/tools/execute looks like a legitimate, well-structured API endpoint that an autonomous agent could safely call?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call structural pre-screen of a URL before committing to deeper integration or workflow execution. It is especially well-suited for agent orchestration pipelines that need to vet unknown or marketplace-sourced API URLs for structural legitimacy and agent-readiness signals before trusting them with live traffic or payments.

## Known failure modes

- Missing or malformed URL input returns a validation error
- URL is syntactically valid but points to a non-API resource, yielding low-evidence findings
- Network or payment failure (x402 USDC payment not processed) blocks the call
- Findings array may be empty if the URL provides no positive or negative signals
- Cloudflare Worker timeout for unusually complex URL parsing edge cases

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object with a 'valid' boolean indicating whether the URL structure is sound, and a 'findings' array containing detailed observations about the URL's path patterns, structural signals, API design quality, and evidence of agent or MCP compatibility.
