How this service works
Call when an agent needs TXT at protonmail._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-protonmail first.
Output
Returns the DNS TXT record value found at protonmail._domainkey.{hostname}, containing the ProtonMail DKIM public key or configuration string used for email authentication verification.
Example use cases
Verify ProtonMail DKIM configuration
“Can you check if ProtonMail DKIM is properly set up for mydomain.com? I need to see the TXT record at protonmail._domainkey.mydomain.com.”
Audit email authentication for client domain
“I'm auditing email deliverability for clientsite.org — can you pull the ProtonMail DKIM TXT DNS record so I can confirm the key is published correctly?”
Diagnose ProtonMail email delivery issues
“We're having trouble with ProtonMail emails being rejected — can you look up the DKIM TXT record at protonmail._domainkey.ourcompany.io to see if the DNS entry looks right?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-txt-dkim-protonmail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to retrieve the ProtonMail DKIM TXT record (protonmail._domainkey selector) for a given hostname. Prefer the free sandbox variant (POST /v1/sandbox/dns-txt-dkim-protonmail) for testing before incurring the $0.007 USDC cost. Choose this over generic DNS lookup tools when you want a focused, pre-scoped ProtonMail DKIM query without constructing the full DNS name yourself.
Side effects
- Hostname not found or does not exist — DNS NXDOMAIN response
- No TXT record present at protonmail._domainkey subdomain — record not configured
- Malformed hostname input exceeding 253 characters or invalid format
- Network timeout when querying DNS
- ProtonMail DKIM record not yet propagated — empty or stale result
