How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

A JSON response indicating success, payment confirmation, and the resolved PTR (reverse DNS pointer) record(s) for the queried IP address or DNS schema — returning the canonical hostname(s) associated with that IP.

Example use cases

Identify server behind IP address

“I have an IP address 104.26.10.78 — can you do a reverse DNS lookup and tell me what hostname or domain it maps to?”

Verify email sender's reverse DNS

“Check the PTR record for IP 209.85.220.41 so I can confirm whether this mail server has proper reverse DNS configured.”

Network audit for unknown IPs

“I'm auditing my server logs and need to know the hostnames for these IPs — start with 1.1.1.1, what PTR record does it have?”

When to prefer

Choose this endpoint when you need a quick, no-signup reverse DNS PTR record lookup paid via USDC micropayment on Base. Ideal for AI agents that need on-demand DNS resolution without managing API keys, especially in automated pipelines where pay-per-call billing via x402 is preferred over subscription-based DNS services.

Side effects

No PTR record exists for the queried IP (NXDOMAIN or empty response)
Invalid or malformed IP address input
Network timeout reaching upstream DNS resolver
Payment not processed or x402 payment rejected
Rate limiting if payment validation fails
