How this service works
Machine-readable settlement service
Output
Returns the DNS TXT record entries for the queried domain, including the string values of each TXT record (such as SPF directives, DKIM keys, verification tokens, DMARC policies, and any other TXT data published in DNS).
Example use cases
Email authentication SPF record check
“Look up the TXT records for acmecorp.com — I need to see what SPF record they have published to diagnose an email deliverability issue.”
Domain ownership verification lookup
“Can you check the DNS TXT records for mybrand.io? I'm trying to confirm whether the Google Search Console verification token has been published yet.”
DMARC policy discovery
“Fetch the DNS TXT records for newsletter.startup.com — I need to see if they have a DMARC policy set and what it says.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/dns.records--txt-record-lookupWhen to prefer
Use this endpoint when you need a quick, programmatic DNS TXT record lookup for a single domain and are operating in an x402 micropayment-enabled agent environment. It is suitable for spot-checking SPF, DKIM, DMARC, or domain verification tokens without setting up your own DNS resolver infrastructure.
Side effects
- Domain does not exist (NXDOMAIN) — returns empty or error response
- No TXT records exist for the queried domain — returns empty records array
- Invalid domain name format in input — returns validation error
- DNS resolver timeout or upstream failure — returns error
- Payment not processed — 402 response requiring x402 micropayment
