AgentPay — pay-per-call APIs for AI agents

No signup, no API key required. Agents pay per request with x402 in USDC on Base or Algorand, or prepay credits.

Domain & Network Lookup

`GET /lookup/v1/dns`	Resolve DNS records (A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, PTR, SRV).	$0.005
`GET /lookup/v1/whois`	Domain registration data (registrar, created/expires, status, nameservers) via RDAP.	$0.01

Endpoint		Price (USDC)
`GET /tools/v1/pdf-text`	Extract per-page text from a PDF URL (up to 20MB).	$0.01
`GET /tools/v1/feed`	Parse an RSS, Atom or JSON Feed into normalized JSON items.	$0.005
`GET /tools/v1/sitemap`	List a site's URLs from its sitemaps (follows robots.txt and sitemap indexes).	$0.005

Paying

Any x402 v2 client works: call an endpoint, receive 402 with a PAYMENT-REQUIRED header, retry with PAYMENT-SIGNATURE. Bad input is rejected before payment and failed calls are never settled. For frequent use, GET /credits/buy?usd=5 returns an API key with bonus credit (+10% at $5, +20% at $20). Agent instructions: llms.txt · index: /.well-known/x402.
