Verified x402 Catalog
10 verified x402 services across 2 chains. Pay per call from your own wallet - no API keys, no custody.
Each service is one verified command (a single endpoint), each verified on-chain with a receipt.
The HTTP standard for AI-agent payments. Built on the long-dormant 402 "Payment Required" status code. Backed by Coinbase, Cloudflare, AWS, Stripe, Google, Visa, Mastercard.
Pay per call from your own threshold-derived wallet. Sippar signs the payment with ICP threshold signatures - no custody, no API keys - and every call settles on-chain with a receipt.
Every service here is Verified: a real payment settled, the service returned a genuine result, and a reviewer confirmed it. Re-checked continuously - anything that breaks drops off.
