# dns-svcb-via-adguard

> dns-svcb-via-adguard is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Resolves SVCB DNS records for a domain via AdGuard DNS over HTTPS, returning records, TTL, response code, DNSSEC validation status, and resolver answer time.

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 dns-svcb-via-adguard-6cdb5f02
```

Example prompt: Can you look up the SVCB records for example.com using AdGuard DNS and tell me what records come back, the TTL, whether DNSSEC was validated, and how fast AdGuard answered?

## When to prefer this

Choose this endpoint when you specifically need SVCB record resolution via AdGuard DNS — particularly to detect AdGuard-specific filtering, compare resolver behavior across providers, check DNSSEC validation status, or measure AdGuard's answer latency for SVCB queries. Prefer this over generic DNS tools when the AdGuard resolver's perspective is the target of interest.

## Known failure modes

- NXDOMAIN returned if domain does not exist or has no SVCB records
- SERVFAIL if AdGuard DNS encounters an upstream error or DNSSEC validation failure
- No SVCB records returned if the domain exists but has no SVCB RRset
- Network timeout if AdGuard DoH endpoint is unreachable
- Payment failure if USDC balance is insufficient for the $0.01 per-lookup fee

## How this service works

SVCB records for a domain as answered by AdGuard DNS (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.

## Output

Returns the SVCB records for the queried domain as answered by AdGuard DNS over HTTPS, including the full record set, TTL value, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer time in milliseconds.
