X402 Integration FAQ
What is X402?
X402 is a payment flow for API requests. When a request requires payment, the API returns payment instructions. The client pays, then retries the request with payment proof.
Why use X402 for this API?
It lets developers and AI agents pay only for the Solana balance queries they use, without creating a monthly subscription first.
How do AI agents use it?
An agent requests a balance, receives payment instructions, completes the payment, and retries with proof to receive the API response.
Do I still need an API key?
Dashboard users can use Bearer API keys. X402 is an alternative flow for pay-per-use clients and autonomous agents.
Can I test before paying?
Yes. Every account starts with 5 free requests before upgrading or using paid request flows.
