## 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 x402-autopay-readiness-matrix-beb0708d -d '<json body>'
```

Example prompt: Before I let you autonomously pay for calls to that x402 API at api.example.com/v1/weather, run an autopay readiness matrix on it — I want to know if the payment envelope, schema quality, price risk, seller breadth, and buyer proof are solid enough to trust without me approving each call.

## When to prefer this

Use this endpoint when an agent needs to decide whether to autonomously pay for an x402 API without human approval — especially when evaluating an unfamiliar route, a new seller, or a high-price endpoint where payment risk assessment is critical before spending.

## Known failure modes

- Unknown or unregistered x402 route returns low registry coverage score
- Route with no buyer proof history returns zero buyer proof score
- Stale or uncrawled endpoint returns low freshness score
- Malformed payment envelope triggers payment envelope quality failure
- Route not found in any known registry returns near-zero composite score

## How this service works

Hosted autopay readiness matrix for agents choosing paid x402 APIs: scores routes by payment envelope quality, schema/examples, buyer proof, price risk, seller breadth, freshness, and registry coverage before autonomous spend.

## Output

A multi-dimensional readiness matrix scoring the x402 route across payment envelope quality, schema/examples completeness, buyer proof, price risk, seller breadth, freshness, and registry coverage — giving the agent a composite signal on whether autonomous spend is safe.
