Sponge Gateway is the easiest way for any service to start accepting x402 payments. Just upload your OpenAPI spec and get endpoints with x402 support that you can route to.

Base Build@buildonbase

You’re losing $$$ if agents can’t pay you. Upload your API docs to @sponge_wallet and they’ll create x402 endpoints built on Base Chain so agents can pay for your services. Agents don’t want to be slowed down. Let them pay ASAP with x402.

AgentMail's APIs should be a part of every agent's workflow. It enables agents to communicate with humans and other agents over the internet's coordination layer, email. Excited to partner with them to enable agents to autonomously create inboxes and send emails without accounts or API keys.

Agents can now create email inboxes with USDC on @base AgentMail supports @CoinbaseDev’s x402 protocol to give agents access to email without accounts or API keys See how it works 👇
