Question 1

How do I deploy Coingate?

Accepted Answer

Clone the repo and start with Docker or bare metal — one command to launch.

Question 2

How does payment work with HTTP 402?

Accepted Answer

When a client requests a pay-gated API endpoint, the gateway returns HTTP 402 with payment requirements. The client signs an ERC-3009 authorization and retries. The gateway verifies, settles USDC on-chain, and delivers the response.

Question 3

What blockchain networks does Coingate support?

Accepted Answer

Coingate supports Base and Base Sepolia, with more EVM chains coming. Each resource endpoint can be independently configured for a specific chain.

Question 4

Do I need to modify my backend code?

Accepted Answer

No. Coingate sits in front of your existing API as a reverse proxy. Configure pay-gated endpoints entirely from the dashboard — your upstream backend stays untouched.
