Payments your agents can make on their own.
Plaidly lets people and AI agents pay each other in stablecoins. One simple API to send money, get paid, and settle on Ethereum and Solana, with more chains on the way — no crypto know-how needed. Your agent gets a wallet and a spending limit; it handles the rest.
Ethereum and Solana today. One ledger. More chains soon.
Ethereum and Solana are live on testnet today. Tron, TON, Polygon, Base and more are on the roadmap — each with its own finality model, all reconciled to one session API you only learn once.
Everything you need to run crypto payments at scale.
Every session, across every chain, in one view. Detect, sweep, finalize, refund — from the browser or the API. No plugins, no wallets to manage.
One spec. Every integration. Ready for AI-assisted development.
An OpenAPI 3.1 document is our single source of truth. Drop it into Cursor, Claude or Copilot for a typed integration in minutes — or install one of the four SDKs we publish on every tag.

Source of truth
One OpenAPI 3.1 spec drives a Go server, four SDKs, Postman and docs — no handwritten types anywhere.
