# x402-gateway Domain Reputation Bundle

> x402-gateway Domain Reputation Bundle is a paid API for AI agents from x402.freeq.one, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-31).

Returns a 0–100 trust score and band for a domain based on registration age, DNS, email authentication, TLS, redirects, and blocklists — no ML, no history, fully deterministic.

## 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-gateway-domain-reputation-bundle-0403b912 -d '<json body>'
```

Example prompt: Can you check whether the domain freeq.one is trustworthy — I want to see its 0-100 trust score based on registration age, DNS, email auth, TLS, and blocklist status?

## When to prefer this

Choose this endpoint when you need a fast, deterministic, rule-based domain trust score without relying on ML models or threat-history databases. It is ideal for pre-flight checks on unknown domains (phishing suspicion, vendor vetting, email sender verification) where you want an objective, reproducible score based on observable infrastructure signals. Prefer it over ML-based threat feeds when you need consistency and auditability, or when integrating into agent workflows that require a clear numeric signal rather than probabilistic verdicts.

## Known failure modes

- Invalid or malformed domain input returns a validation error
- Private or reserved domains (e.g. localhost, .local) may return no meaningful score
- Domains with no public DNS records may return incomplete signal data
- Network or DNS lookup timeouts may cause partial results
- Payment failure (insufficient USDC on Base) blocks the request

## How this service works

Domain Reputation Bundle: Domain reputation bundle: 0-100 trust score and band from registration age, DNS, email auth, TLS, redirects and blocklists. Deterministic — no malware verdicts, no history. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/domain_reputation.

## Output

A structured response containing a numeric trust score from 0 to 100, a trust band (e.g. low/medium/high), and individual signal assessments covering domain registration age, DNS configuration, email authentication (SPF/DKIM/DMARC), TLS certificate validity, redirect behavior, and blocklist presence — all computed deterministically without ML or historical malware verdicts.
