Identity, payment, and execution — combined into a single request. Let machines transact autonomously in USDC, settled on-chain, verified in milliseconds.
Chex issues short-lived payment tokens that travel alongside any API call. Servers verify, redeem, and settle in USDC — no invoices, no intermediaries, no waiting.
Sender and receiver onboard once. Chex provisions a USDC wallet on Base, instantly ready to transact.
The sender calls /v1/tokens with a price. Chex returns a signed x-token — a one-time payment credential.
The receiver server accepts the token, verifies it with Chex, and confirms funds — all in under 50ms.
Chex debits the sender and credits the receiver in USDC. The API delivers the task. Done.
Add autonomous payments to any API in four lines of code. Whether you're the agent paying or the service receiving, integration is symmetric.
Verified, debited and credited in under 50 milliseconds on Base. No card rails, no float, no disputes window.
Every Chex account is a smart-contract wallet pre-funded with USDC. Programmable, auditable, borderless by default.
x-tokens are single-use, scoped to a price, and expire in seconds. Safe to pass in headers, impossible to replay.
Every token carries a verified sender ID. Receivers get KYA-grade provenance on who paid, not just that they did.
REST, gRPC, MCP, webhooks, queues. If it can hold a header, it can charge for its work. No SDK required.
Charge $0.0001 a request without a payment processor laughing. Finally viable economics for autonomous commerce.
