How this service works
Pay-per-call utilities for AI agents, no API key or signup: read any web page as clean Markdown ($0.002), link/SEO metadata ($0.001), domain DNS + SPF/DMARC email-security audit ($0.003), ERC-20 token safety pre-check ($0.005), crypto address validation, on-chain payment verification, EIP-681/BIP21/Solana Pay payment requests with QR, multichain USDC balances ($0.01). x402 v2, USDC on Base. Invalid input / upstream failure is never charged.
Output
Returns a JSON object containing the domain name, whether it exists, a list of findings with severity levels (e.g. missing MX records), email authentication details (SPF record string, DMARC record string, DMARC policy value), a numeric hygiene score from 0–100, and a boolean DNSSEC validation flag.
Example use cases
Pre-send email deliverability check
“Before we send this campaign, check whether our domain mailchimp-example.com has valid SPF and DMARC records set up and what our email security hygiene score looks like.”
Vendor phishing risk assessment
“I'm about to onboard a new vendor at acme-supplier.io — can you check their domain's email security config, specifically whether they have DMARC with a reject or quarantine policy, so I know if they're a phishing risk?”
Competitor domain security audit
“Can you pull the full DNS and email authentication details for competitor.com — I want to see their SPF, DMARC policy, whether DNSSEC is validated, and any security findings or warnings.”
Technical details
Endpoint
GEThttps://devx-x402-tools.nextill-pos.workers.dev/v1/domain/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call DNS and email security audit without API key setup. It is ideal for one-off domain checks, vendor assessments, or pre-send deliverability validation. Prefer it over manual DNS lookups or multi-tool pipelines when you need SPF, DMARC, MX, DNSSEC, and a composite hygiene score in a single response.
Side effects
- Domain does not exist or is unresolvable — returns exists:false with relevant findings, no charge
- Invalid domain format input — returns 400 error, no charge
- Upstream DNS resolver failure — returns error, no charge
- Timeout from upstream DNS infrastructure — returns error, no charge
