# DKIM SES DNS TXT Lookup (ses._domainkey)

## 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-ses-dns-txt-lookup-ses-domainkey-3d4b2a8f -d '<json body>'
```

Example prompt: Can you look up the DKIM TXT record for Amazon SES on the domain example.com — specifically the one at ses._domainkey.example.com?

## When to prefer this

Use this endpoint when you specifically need the TXT record at the ses._domainkey selector for a domain — the canonical DKIM selector used by Amazon SES. For other DKIM selectors (e.g. pic._domainkey, mandrill._domainkey), use the corresponding sibling endpoints. Prefer the free sandbox equivalent (/v1/sandbox/dns-txt-dkim-ses) for testing before paying $0.006 USDC per call.

## Known failure modes

- No TXT record exists at ses._domainkey.{hostname} — returns an error indicating the record is absent
- Invalid or malformed hostname input — validation error
- DNS resolution timeout or network error
- Domain does not use Amazon SES and has no ses._domainkey record

## How this service works

Call when an agent needs TXT at ses._domainkey.{hostname}. A different selector is a different DNS name. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/dns-txt-dkim-ses first.

## Output

Returns the content of the DNS TXT record at ses._domainkey.{hostname}, typically containing the DKIM public key (p=...) used by Amazon SES for email signing and authentication. Returns an error if the record does not exist.
