## 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 open-data-proxy-domain-trust-ssl-assessment-api-11662d9d
```

Example prompt: Can you check the trust score and SSL certificate status for thesoulnetwork.eu and tell me how many days until the cert expires and what mail security grade it has?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call domain trust and SSL assessment without a subscription — ideal for one-off vendor due diligence, onboarding checks, or monitoring a small set of domains. Prefer this over larger security platforms when cost-per-call efficiency matters and you only need trust score, SSL expiry, and mail grade rather than a full penetration report.

## Known failure modes

- Invalid or non-existent domain returns error or empty result
- Payment failure on Base Mainnet causes 402 response blocking the call
- Domain with no SSL certificate may return null or zero daysToExpiry
- Rate limiting or network issues may cause timeouts
- Malformed domain string (e.g. missing TLD) may return validation error

## How this service works

Pay $0.01 USDC per call to validate IBANs, EU VAT numbers and Dutch postcodes, and to query CBS housing, company, domain and EU sanctions data on Base Mainnet.

## Output

Returns a JSON object containing: trustScore (0-100 integer), sslInfo.daysToExpiry (integer days until SSL cert expires), mailGrade.grade (letter grade e.g. 'A') and mailGrade.score (0-100), and assessmentDate (ISO 8601 timestamp of when the assessment was performed).
