x402 Web Tools – DNS Lookup

Choose this endpoint when you need authoritative, real-time DNS record data from both Cloudflare and Google resolvers for any domain. It's ideal for verifying email configuration (SPF, DKIM, MX), debugging DNS propagation, auditing domain infrastructure, or confirming domain existence. Prefer it over manual DNS tools when automating DNS checks in an agent workflow, especially when you need multiple record types in a single call. It pays per-call via x402 microtransactions, so it suits low-volume, on-demand lookups rather than bulk domain scanning.

• Domain does not exist — exists field returns false and records may be empty
• Invalid domain name format — likely returns an error or empty result
• Requested record type not found — that type is simply omitted from the records object
• DNS resolver timeout or upstream failure — may return a partial result or error
• Comma-separated types string is malformed — may return all types or an error
