Use Case Guide

Choose the right API surface for your integration scenario.

Choose Business API when

• You issue and manage API keys from a dashboard or partner workflow
• Your backend wants classic request signing
• You need webhook administration
• Your operators do not want wallet handling in the integration

Choose x402 API when

• Your client already controls a wallet
• You want paid routes priced directly at the HTTP layer
• You need premium automation like route analysis or market-intel jobs
• You can implement x402 pay-and-retry plus SIWX for wallet-bound reads
