Agent Commerce Gateway is a self-hosted, non-custodial gateway that puts an existing HTTP API in front of AI agents, exposing its endpoints over HTTP or MCP and charging for them with x402 or experimental MPP payments. Paid calls settle in USDC on EVM networks such as Base through EIP-3009 transferWithAuthorization, straight to the merchant wallet, so builders can charge agents per request without adding payment code to their backend.

x402

x402 is an open payments protocol built on the HTTP 402 status code that lets an application or agent pay per request in stablecoins without accounts or API keys. Builders add its middleware to a service to charge per call, or to a client so it can pay.

web3-ethereum-defi

web3-ethereum-defi is a Python library for DeFi integration and data research, with wrappers for Uniswap, Aave, Chainlink, and USDC on top of web3.py. Python builders import it instead of writing those protocol wrappers themselves.

Request Network

Request Network is a protocol and JavaScript library for creating, paying, and tracking crypto invoices and payment requests onchain. Builders install the client library to add invoicing to their own application.

AaveKit

AaveKit is Aave's SDK, a TypeScript client and React hooks over the Aave GraphQL API. Builders use it to read markets and user positions and to build supply, borrow, repay and swap transactions without calling the contracts by hand. Aave v3 and v4 are served by separate SDK versions of the same packages (0.x for v3, 4.0 and later for v4).

crossmint

Crossmint offers stablecoin APIs aimed at enterprises, including cross-chain flows. Builders use it to add stablecoin payments to an application without building the payment rails.

Stripe Crypto Onramp

Stripe Crypto Onramp is an embeddable fiat-to-crypto onramp SDK for web, iOS, Android, and React Native that delivers purchased crypto to a user's wallet. Builders embed it so users can fund a wallet with a card instead of transferring in.
