# DKIM Ionos Selector Lookup

> DKIM Ionos Selector Lookup is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Looks up and parses the DKIM public key for the 'ionos' selector (ionos._domainkey.<domain>) via Cloudflare DoH, returning key type, length, testing flag, and revocation status.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dkim-ionos-selector-lookup-6ca7b4ba
```

Example prompt: Check the DKIM record for the ionos selector on example.com — I want to know if the key is active, what type it is, how long the public key is, and whether it's been revoked.

## When to prefer this

Use this endpoint when you specifically need to inspect the DKIM configuration for the 'ionos' selector on a domain — particularly for domains hosted or managed through IONOS mail services. Prefer this over generic DNS TXT lookups when you need structured parsing of DKIM fields (key type, length, revocation, testing flag) rather than raw TXT data.

## Known failure modes

- Domain has no ionos._domainkey TXT record — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — network or timeout error
- Malformed TXT record that cannot be parsed — partial or error response
- Payment not processed — x402 payment required error
- Domain input missing or invalid — request error

## How this service works

DKIM public key for selector "ionos" of a domain: looks up ionos._domainkey.<domain> (TXT, Cloudflare DoH) and parses v=, k=, key type, public-key length, testing flag and whether the key is revoked (empty p=). Confirms that mail signed with the ionos selector will verify. $0.01 per lookup.

## Output

Returns parsed details from the ionos._domainkey.<domain> TXT record including: the DKIM version (v=), key type (k=, e.g. rsa or ed25519), public key length in bits, whether the record is in testing mode, and whether the key is revoked (empty p= field). Indicates whether mail signed with the ionos selector should pass DKIM verification.
