How this service works
Call when an agent needs TXT at _dnslink that contains dnslink=. Send JSON {"hostname":"example.com"}. Exact $0.01 USDC on Base. Try unpaid POST /v1/sandbox/dns-txt-dnslink first.
Output
Returns the TXT record content found at the _dnslink subdomain of the provided hostname, specifically the dnslink= value indicating the IPFS, IPNS, or other distributed web path the domain resolves to.
Example use cases
Resolve IPFS content for a domain
“I need to find what IPFS content the domain en.wikipedia-on-ipfs.org is pointing to — can you look up its _dnslink TXT record and tell me the dnslink= value?”
Verify DNSLink configuration for a site
“I'm setting up a dnslink for my site at myproject.example.com and want to confirm it's resolving correctly — can you query the _dnslink TXT record and show me what dnslink= value it returns?”
Find distributed web address for a dapp
“Can you check what distributed web address uniswap.eth.link is pointing to via DNSLink — fetch the _dnslink TXT record and tell me where it resolves?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-dnslink?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to resolve a DNSLink TXT record at the _dnslink subdomain of a hostname, such as when navigating IPFS/IPNS content addressed via human-readable domain names. Prefer the unpaid sandbox version (/v1/sandbox/dns-txt-dnslink) for testing. Choose this paid endpoint when the sandbox is unavailable or rate-limited.
Side effects
- No _dnslink TXT record exists for the hostname — returns empty or error response
- Invalid or malformed hostname input — validation error
- DNS lookup timeout or resolution failure — network error
- Hostname exists but TXT record does not contain dnslink= prefix — may return empty or unexpected result
- Payment of $0.01 USDC not provided — 402 Payment Required response
