# X402 Data API – Domain Intelligence

> X402 Data API – Domain Intelligence is a paid API for AI agents from api.x402dataapi.com, paid per call via x402, $1/call, status unknown (last checked 2026-09-15).

Performs deep domain inspection including DNS, TLS, HTTP headers, mail security, fingerprinting, and risk scoring for a given public domain name

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-data-api-domain-intelligence-0c474459 -d '<json body>'
```

Example prompt: Can you run a full domain intelligence check on stripe.com — I want to see its DNS config, TLS setup, mail security (SPF/DKIM/DMARC), and what risk score it gets?

## When to prefer this

Use this endpoint when you need a comprehensive, multi-signal technical assessment of a public domain — covering DNS, TLS, HTTP, mail security, and risk scoring in a single call — especially in automated pipelines where per-request micropayment via x402 is acceptable and you need structured JSON output for downstream processing.

## Known failure modes

- Invalid or non-public domain name returns an error or empty result
- Domain is unreachable or DNS does not resolve, resulting in partial or null fields
- Payment not attached or insufficient USDC balance triggers 402 Payment Required
- Malformed domain string (e.g. includes protocol or path) may cause parsing error
- Rate limiting or facilitator issues may cause transient failures

## How this service works

Paid x402 API for AI agents that returns domain intelligence, DNS lookup data, domain risk signals, security posture, WHOIS-like technical data, mail security, TLS, HTTP headers, fingerprinting and AI agent domain analysis for a public domain.

## Output

A JSON object containing DNS records, TLS certificate details, HTTP header analysis, mail security configuration (SPF, DKIM, DMARC), a server/technology fingerprint, a numeric risk score, and a human-readable summary array for the inspected domain
