How this service works
Pay-per-call API for AI agents, settled in USDC on Base mainnet (eip155:8453) via the x402 protocol - no API keys, no signup, no subscription. Live crypto market data: BTC, ETH, SOL, USDC (USD Coin) prices with 24h change (source: OKX), Base mainnet chain snapshot (block height, gas price gwei), real-time USDC-on-Base transfer analytics (transfer count, volume, unique senders and recipients over recent blocks), and USDC/ETH wallet balances plus nonce for any address. Agent utility tools: deterministic JSON repair for LLM output (strip code fences, fix trailing commas, single quotes, unquoted keys, balance braces), DNS A/AAAA lookup, and URL extraction from arbitrary text. Every endpoint returns HTTP 402 with an x402 payment challenge in USDC on Base; pay with any wallet and retry with the PAYMENT-SIGNATURE header. MCP server at /mcp (streamable HTTP, 6 pay-per-call tools). Ideal for crypto portfolios, DeFi dashboards, market analysis agents, data pipelines, and LLM post-processing.
Output
Returns DNS A (IPv4) and AAAA (IPv6) records for the queried hostname, indicating what IP addresses the domain resolves to. Response is JSON. Requires x402 micropayment of $0.001 USDC on Base mainnet before data is returned.
Example use cases
Validate domain reachability before API call
“Before we call that webhook, can you look up the DNS records for webhooks.myservice.io and confirm it actually resolves to an IP address?”
Check IPv6 support for a hostname
“Does dashboard.mycompany.com have AAAA records set up? I need to know if it supports IPv6.”
Debug misconfigured domain in pipeline
“We're getting connection failures to data.partner-site.com — can you pull its DNS A records to see where it's currently pointing?”
Technical details
Endpoint
GEThttps://baseusdcearn.pythonanywhere.com/net/dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-signup DNS resolution tool payable in USDC micropayments via x402, particularly in crypto-native agent pipelines that already handle x402 payments for other calls on this platform. Best for one-off DNS checks without wanting to manage API keys or subscriptions.
Side effects
- Domain does not exist — NXDOMAIN response or empty record set
- No A or AAAA records present for the domain (only MX, CNAME, etc.)
- HTTP 402 returned if payment not submitted or payment signature invalid
- Network/DNS resolver timeout for slow or unreachable nameservers
- Malformed domain name input causing lookup failure
