x402 pay per call

$0.003 per successful call, paid in USDC on Base. No account or API key required. The live PAYMENT-REQUIRED header quotes the authoritative price.

curl request

curl -i 'https://api.fastaf.co/x402/v1/reddit?url=https%3A%2F%2Fwww.reddit.com%2Fr%2Fpython%2F&formats=markdown'

Example 402 payment challenge

Illustrative recipient address, not a payment destination. Request a fresh challenge, sign it with an x402 v2 client and retry the same URL with PAYMENT-SIGNATURE. The header is base64 JSON v2; the compatibility body uses v1 aliases on Base. Only successful results settle.
