## 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 moneytest-x402-seller-readiness-checker-6143f42b -d '<json body>'
```

Example prompt: Can you check if my x402 API is ready for marketplace listing? Here's my OpenAPI spec and service manifest — I want to know my readiness tier and what blockers I need to fix before going live.

## When to prefer this

Choose this endpoint when you need a deterministic, scored assessment of whether a service is ready to sell via the x402 protocol on Base or Algorand — particularly when you want specific blockers and a tier classification rather than a generic OpenAPI validator. Prefer this over generic linters when your goal is marketplace listing eligibility.

## Known failure modes

- Malformed or missing OpenAPI object returns validation error
- Invalid manifest structure causes schema mismatch
- Missing x402 challenge object may result in incomplete scoring
- Payment of $0.05 USDC required; unpaid requests return 402 Payment Required
- Low score with blockers returned when service fails critical checks

## How this service works

Deterministic agent utilities and launch kits paid on Base or Algorand mainnet through x402 v2.

## Output

Returns a JSON object with a readiness tier (e.g. 'marketplace-ready'), a numeric score (0-100), a list of passed checks, a list of blockers preventing listing, a receipt SHA-256 hash, and an optional implementation offer with currency and price in USD.
