## 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 survival-colony-x402-agent-readiness-review-0dd76cd9 -d '<json body>'
```

Example prompt: Can you run an agent-readiness review on this service description and tell me the readiness score, any payment or security issues, and what I should fix first: 'This API accepts USDC via x402 on Base and returns weather data for a given city'?

## When to prefer this

Choose this endpoint when you need a structured, scored evaluation of an API or agent service description specifically targeting x402 payment readiness, agent discoverability, and usability — rather than generic code linting, spec validation, or a manual review. It is especially useful before publishing a service to AI agent marketplaces or x402 directories, and when you need actionable, prioritized fixes rather than raw feedback.

## Known failure modes

- Text field empty or missing — validation error returned
- Text exceeds 4000 character limit — rejected with error
- Instruction exceeds 500 characters — rejected with error
- Payment not received or x402 handshake fails — 402 response before analysis runs
- Malformed JSON body — 400 error
- Upstream AI model timeout — 5xx error with no score returned

## How this service works

Low-cost AI analysis, extraction, summarization and risk-review APIs payable with USDC via x402 on Base.

## Output

Returns a JSON object containing a plain-English verdict, categorized issue lists (payment_issues, security_issues, discovery_issues, agent_usability_issues), a list of prioritized_fixes, next_validation_steps, and a numeric readiness_score_0_100 indicating overall agent-readiness of the submitted service.
