> DKIM Selector scph0316 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 2026-10-20).

Looks up and parses the DKIM public key for the 'scph0316' selector of a given domain via Cloudflare DoH, returning key type, length, testing status, and revocation state.

## 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-selector-scph0316-lookup-c33d39fb
```

Example prompt: Can you check whether the scph0316 DKIM selector is properly set up for example.com — I want to know if the key is active, what type it is, how long it is, and whether it's been revoked?

## When to prefer this

Use this endpoint when you specifically need to validate or inspect the scph0316 DKIM selector for a domain — common for ESPs, email platforms, or senders using the SendGrid scph0316 selector. Prefer this over generic DNS TXT lookup tools when you need structured DKIM field parsing (key type, length, revocation, testing flag) rather than raw TXT record text.

## Known failure modes

- Domain does not have a scph0316._domainkey TXT record — returns not found or empty result
- DNS lookup fails due to network or Cloudflare DoH unavailability
- Malformed TXT record that cannot be parsed into DKIM fields
- Payment not provided or insufficient — returns 402 Payment Required
- Domain input missing or invalid format

## How this service works

DKIM public key for selector "scph0316" of a domain: looks up scph0316._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 scph0316 selector will verify. $0.01 per lookup.

## Output

Returns parsed details from the scph0316._domainkey.<domain> TXT record including the DKIM version (v=), key type (k=), public key length in bits, whether the domain is in testing mode (t=y), and whether the key is revoked (empty p= field), plus a confirmation of whether mail signed with this selector will pass verification.
