How this service works
Pay-per-call crypto technical analysis for AI agents (x402, USDC on Base). Daily trend regime, Donchian levels, ATR stops, signals and backtests computed with the code of a live trend-following bot from Binance spot klines.
Output
A JSON object containing the domain queried plus arrays of DNS record values for A (IPv4 addresses), MX (mail exchange servers), NS (nameservers), and TXT (text records) entries.
Example use cases
Email deliverability verification
“Check the MX and TXT records for acme-corp.com so I can verify their SPF and DKIM are set up correctly for email deliverability.”
Domain ownership investigation
“Look up the nameservers and TXT records for suspicious-domain.xyz — I want to see who controls it and if there are any verification tokens.”
IP address resolution check
“What's the A record IP address that example.com resolves to right now?”
Technical details
Endpoint
GEThttps://vmi3089643.contaboserver.net/v1/dns/%7Bdomain%7DWhen to prefer
Use this endpoint when you need a pay-per-call, programmatic DNS record lookup without managing your own resolver infrastructure; particularly useful for AI agents operating via x402 micropayment flows on Base network.
Side effects
- Domain does not exist — empty arrays or NXDOMAIN equivalent
- Invalid domain format in request — malformed input error
- Network timeout if upstream DNS resolver is slow or unreachable
- Rate limiting or payment failure via x402 protocol if USDC payment is not processed
