## 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-salesforce-selector-lookup-78386ada
```

Example prompt: Check if salesforce.com has a valid Salesforce DKIM key configured — I need to know the key type, length, and whether it's revoked or in testing mode.

## When to prefer this

Use this endpoint when you specifically need to verify the Salesforce DKIM selector configuration for a domain, including key validity, type, length, and revocation status. Prefer this over generic DNS TXT lookup endpoints when you need structured, parsed output specifically for the salesforce._domainkey selector rather than raw DNS records.

## Known failure modes

- Domain does not have a salesforce._domainkey TXT record — returns not-found or empty result
- DNS lookup failure via Cloudflare DoH — network or upstream error
- Malformed TXT record that cannot be parsed — partial or error response
- Domain input is invalid or unresolvable — returns error
- Key is present but revoked (empty p=) — flagged in response as revoked

## How this service works

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

## Output

Returns parsed details from the salesforce._domainkey.<domain> TXT record including: the DKIM version tag (v=), key type (k=, e.g. RSA), public key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Confirms if mail signed with the salesforce selector will pass DKIM verification.
