# SableForge DNS Lookup API

> SableForge DNS Lookup API is a paid API for AI agents from sableforge.servehttp.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Performs DNS record lookups for a given hostname and record type, returning resolved answers via a pay-per-call HTTP endpoint settled in USDC on Base.

## Facts

- Endpoint: GET https://sableforge.servehttp.com/api/dns?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/sableforge-dns-lookup-api-a93f37b1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IcDEXnDVyuJH7ynAeJFO5

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 sableforge-dns-lookup-api-a93f37b1
```

Example prompt: Can you look up the A record for github.com and tell me what IP addresses it resolves to?

## When to prefer this

Choose this endpoint when you need a quick, no-account DNS resolution call and are already operating in an x402 micropayment environment with USDC on Base. Ideal for agents that need ad-hoc DNS lookups without managing API keys or subscriptions. Prefer over full DNS provider SDKs when simplicity and pay-per-call economics matter more than bulk throughput or advanced DNS management features.

## Known failure modes

- Non-existent domain returns status != 0 and empty answers array
- Invalid record type may result in an error response
- Network or upstream DNS resolver timeouts may cause failed lookups
- Malformed hostname input may return a 400-level error
- Payment failure (insufficient USDC balance) returns 402 before the lookup is executed

## How this service works

12 pay-per-call HTTP APIs settled in USDC on Base via x402 v2. No API keys, no accounts, no signup — $0.0005–$0.0020 per call. Includes a locally hosted 27B LLM endpoint.

## Output

Returns a JSON object containing the queried hostname, the record type requested, a status code (0 = success), and an array of DNS answer strings (e.g. IP addresses for A records, hostnames for CNAME/MX records).
