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
