# GENESIS Agent Tools — API Compatibility Suite

> GENESIS Agent Tools — API Compatibility Suite is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-01).

Analyzes two API versions (current vs. previous) for breaking compatibility changes and returns a pass/fail verdict with blocking findings

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-api-compatibility-suite-d228476d -d '<json body>'
```

Example prompt: Can you run a compatibility check between my new API schema and the previous version to see if there are any breaking changes blocking deployment?

## When to prefer this

Choose this endpoint when you need a pay-per-call, cryptographically signed API compatibility verdict with explicit blocking findings — particularly in agent-driven CI/CD pipelines or autonomous deployment workflows where a trusted, auditable pass/fail signal is required. Prefer this over manual schema diffing tools when operating on Base USDC x402 infrastructure or when the signed result needs to be programmatically verified downstream.

## Known failure modes

- Missing required 'current' or 'previous' fields returns a validation error
- Malformed or non-object schema inputs may return a 400-level error
- Payment failure via x402 (insufficient USDC balance) results in a 402 Payment Required response
- Network timeout on the Cloudflare Worker may return a 5xx error
- Passing identical schemas may return pass=true with empty blocking_findings (valid but trivial)

## 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 containing: a boolean 'pass' field indicating whether the API versions are compatible, a cryptographic 'signature' field authenticating the result, and a 'blocking_findings' array listing any breaking changes or incompatibilities detected between the current and previous API schemas.
