Built for builders.

Three lines to autonomous commerce. TypeScript-native. Framework-agnostic. Designed for agents that move fast.

Everything your agent needs.

Conditional Escrow

Lock funds with programmable release conditions. Time-bound, event-bound, or multi-signal.

axiscurv.lock({ condition: 'delivery' })

Instant Settlement

Sub-200ms from verification to fund transfer. No batching. Atomic.

await escrow.release() // <200ms

Event Webhooks

Real-time callbacks for every state change. Lock, verify, release, timeout.

axiscurv.on('released', handler)

Multi-Party Escrow

Split payments across providers. Parallel locks. Coordinated releases.

axiscurv.lockMulti([...providers])

Agent Authentication

Cryptographic identity for every agent. No shared keys. Scoped permissions.

new AxisCurv({ agentId, secret })

Transaction Monitoring

Full lifecycle visibility. Dashboards, logs, alerts. Know what your agents spend.

axiscurv.transactions.list({ status })

Fits your stack.

Framework-agnostic. Drop into any agent architecture.

From this. To this.

WITHOUT PRAXIS
// Manual payment orchestration
const stripe = new Stripe(COMPANY_KEY) // shared key
const charge = await stripe.charges.create({
  amount: computeEstimate(), // estimate, not actual
  source: companyCreditCard, // full access
  description: `agent-${id}-task-${taskId}`
})
// Hope the service delivers...
// No verification...
// No recourse if it doesn't...
// Manual reconciliation later...
await notifyHumanForApproval() // blocked
await waitForHumanResponse() // minutes to hours
WITH PRAXIS
const escrow = await axiscurv.lock({
  amount: 2.50,
  provider: 'compute.service',
  condition: 'delivery.verified'
})

// Agent works autonomously.
// Verification is automatic.
// Settlement is instant.

await escrow.release() // Done. No human needed.

Full lifecycle visibility.

Hook into every state change. Monitor. React. Control.
