Agent Intel Dnssec Trust Chain Validator

by SiteCheck Agent Intel & Dev in Developer tools

x402 APIFailing, checked 8 h ago

DNSSEC status for a domain using Cloudflare's public resolver (1.1.1.1 DNS-over-HTTPS): whether the resolver validated the answer (AD flag), the DS records in the parent zone, and the DNSKEY records with key-signing keys. The validation is done by Cloudflare's resolver, not by this tool walking the chain to the root.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.001.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.fadeandco.workers.dev/api/agent-intel/dnssec-trust-chain-validator?domain=ietf.org'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://api.fadeandco.workers.dev/api/agent-intel/dnssec-trust-chain-validator?domain=ietf.org' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
