PLATFORM

Every primitive you need to let agents pay safely.

Policy, signing, settlement, and observability — composable, scoped, and revocable in one call.

Spend caps & velocity limits

Per-agent, per-day, per-category. Hard ceilings enforced at the network edge.

Cryptographic provenance

Every authorized payment is signed Ed25519. Verifiable, replay-protected, audit-grade.

Allowlists & deny-by-default

Pin agents to specific sellers, domains, or categories. Everything else fails closed.

Real-time observability

Stream every decision to your warehouse. Webhooks for breaches, retries, settlement.

Built on x402

Standard HTTP 402 challenge / response. Works with any seller, any agent, any stack.

Instant USDC settlement

Sub-second clearing on Base. Optional bridges to USD payouts and invoicing.

DEVELOPER EXPERIENCE

Twelve lines of code on each side.

Agents wrap fetch. Sellers wrap a handler. Mandate handles the 402 dance, policy enforcement, signing, and retry.
