Build agents
that transact.
Autonomously.
Delegated card spending, real-time metering, and autonomous settlement. Fiat and crypto, through one integration - any protocol, any PSP, any payment rail.
One platform, every building block.
Integrate however you build: SDKs, a CLI, an MCP server, REST APIs, and a dashboard - all on one account.
Install, register, get paid.
A thin wrapper in front of what you already run. Your checkout and fulfillment logic stay untouched.
Install
npm install @nevermined-io/payments
TypeScript shown · Python: payments-py
Initialize
const payments = Payments.getInstance({
nvmApiKey: NVM_API_KEY,
environment: "live",
})One key, sandbox or live
Protect your route
// no payment? answer with the challenge
return buildPaymentRequired(planId, {
endpoint, httpVerb, scheme, environment,
})A thin wrapper - checkout logic unchanged
Verify, serve, settle
await payments.facilitator.verifyPermissions({...})
// serve the resource, then:
await payments.facilitator.settlePermissions({...})Settle before delivery, on your PSP
Charge the way your agent creates value.
Cost-plus, per-use, or per-outcome - meter it your way and settle profitably at any ticket size, even sub-dollar.
Cost-based
Cost-plus marginLink usage to your infrastructure spend, then layer on your own margin - turn variable costs into predictable profit.
Usage-based
Pay per requestCharge for every request, API call, token, dataset, or compute cycle. Heavy users pay more than casual ones.
Outcome-based
Success-based feesOnly charge when the agent delivers real value - meetings booked, leads qualified, issues resolved, deals closed.
Trusted agents, verifiable from day one.
On-chain identity, scoped smart accounts, and a complete audit trail - out of the box.
ERC-8004 agent identity
Verifiable, portable identity across deployments and frameworks. An on-chain registry prevents spoofing; signature checks prove provenance.
ERC-4337 smart accounts
Session keys let agents settle autonomously - scoped permissions, time-bound access, automatic revocation. No private-key custody.
Audit-ready from day one
An end-to-end trace of every request, policy change, and payout. Timestamped proofs export straight into compliance reporting.
Enterprise-grade certifications - put us in front of your auditors. Trust Center ↗
One integration, no lock-in
Fiat and crypto, across any protocol, PSP, and chain. Whatever standard wins, your agents already speak it.
From install to income, in the docs.
Guides, full API reference, and the MCP server - everything to go from npm install to settled revenue.
