Ecosystem

The Solgateskit ecosystem

Everything you need to build, test, and deploy pay-per-request APIs on Solana. From client SDKs to protocol specs — all open source.

SDK

The core npm package. Drop-in fetch wrapper that attaches Solana payments to any HTTP request. Works in Node.js, browsers, and edge runtimes.

npm install @solgateskit/client

Server

Express/Next.js/Hono middleware that validates payment headers, confirms transactions on-chain, and gates access to your endpoints.

npm install @solgateskit/server

Playground

Browser-based playground to test pay-per-request flows against devnet. Simulate payments, inspect headers, and debug integration issues in real time.

playground.solgateskit.dev

Protocol

The open protocol specification. Defines how payment requirements are communicated via HTTP 402 headers, transaction formats, and verification flows.

X-Solana-Pay / X-SGK-Price headers

Token

Governance and utility token. Stake to reduce protocol fees, vote on upgrades, and earn from the network's transaction volume.

Governance + fee reduction

Community

Built in the open. Contribute on GitHub, follow updates on X, and install packages from npm. Join the developers building the pay-per-request web.
