# DKIM OVH Selector Lookup

> DKIM OVH 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 2026-10-20).

Looks up and parses the DKIM public key for the 'ovh' selector of a given domain by querying ovh._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-ovh-selector-lookup-1c9d45c9
```

Example prompt: Can you check if example.com has a valid OVH DKIM selector set up — I want to know the key type, key length, whether it's in testing mode, and if it's been revoked?

## When to prefer this

Use this endpoint when you specifically need to check the OVH DKIM selector for a domain — particularly when verifying that OVH-hosted email is correctly signed or diagnosing OVH email deliverability issues. Prefer this over generic DNS TXT lookup endpoints when you need parsed DKIM fields (key type, length, revocation status) rather than raw TXT record data.

## Known failure modes

- Domain has no ovh._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 into DKIM fields
- Payment failure — x402 payment of $0.01 USDC not processed correctly
- Rate limiting or timeout from the DNS resolver

## How this service works

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

## Output

Returns parsed DKIM record fields from ovh._domainkey.<domain>: the v= version tag, k= key type (e.g. RSA), the public key length in bits, whether the testing flag is set, and whether the key is revoked (empty p= field). Confirms whether mail signed with the OVH selector will successfully verify.
