Get an API Key

Prepay for credits via Stripe. Use your API key in the Authorization header.

Sign up

Enter your email. We'll send you a Stripe payment link to fund your account. Once paid, you'll receive your API key.

Usage

Include your API key in the Authorization header:

# Example request
curl -X POST https://api.agentutil.dev/v1/tools/dns.lookup/tasks \
  -H "Authorization: Bearer sk_live_xxxxx" \
  -H "Content-Type: application/json" \
  -d '{"domain": "example.com"}'

Pricing

Same per-request pricing as x402. Your prepaid balance is deducted with each API call.

  • — $10 minimum — good for ~1,000+ requests
  • — No expiration — credits never expire
  • — No monthly fees — pay only for what you use

Prefer autonomous payments? Use x402 instead — no signup required. Your agent pays per-request with USDC on Base. Learn more →
