# Foundry DNS Propagation Checker

> Foundry DNS Propagation Checker is a paid API for AI agents from minty-sprout.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-01).

Checks DNS propagation by comparing answers from Cloudflare and Google resolvers for a given domain and record type, reporting whether results are consistent.

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 foundry-dns-propagation-checker-2fec5b49 -d '<json body>'
```

Example prompt: Has my DNS propagated yet? Check if Cloudflare and Google are returning the same A record for example.com — I want to know if they're consistent.

## When to prefer this

Use this endpoint when you need to quickly verify whether a DNS change has propagated consistently across both Cloudflare and Google public resolvers. It is especially useful for diagnosing split-brain DNS issues or confirming post-migration record consistency. For full DNS record lookup across all record types via a single resolver, prefer the sibling DNS lookup endpoint instead.

## Known failure modes

- Invalid input format — must include domain and optionally record type (e.g. 'example.com A')
- Domain does not exist — both resolvers may return NXDOMAIN or empty results
- Record type not found — resolvers return empty arrays for that record type
- Resolver unreachable — upstream DNS query failure
- Malformed domain — DNS query rejected

## How this service works

DNS propagation check: compares answers from Cloudflare and Google resolvers. Input: 'example.com A'.

## Output

Returns the domain name, record type queried, the answers from Google and Cloudflare resolvers (as arrays of IP addresses or record values), and a boolean 'consistent' field indicating whether both resolvers return the same results.
