# Overview

> Nevermined is building the financial rails for AI. Monetize agents and enable autonomous agent-to-agent payments with real cards.

AI agents need to pay and get paid, but traditional payment infrastructure wasn't built for that. Three problems stand in the way:

* **Agents can't spend autonomously** - no way to delegate a real payment method with controlled limits
* **Merchants can't accept agentic payments** - no metering, no per-request settlement, no programmatic access control
* **Everyone's locked to one provider** - rigid integrations that don't work across frameworks or payment processors

Nevermined solves all three. Put a payment gate in front of any API, charge per request, and settle automatically. You handle the AI, we handle the rest.

## How It Works

<img src="https://mintcdn.com/neverminedag/0I7otPhM-HhzCbrN/images/payment-flow.png?fit=max&auto=format&n=0I7otPhM-HhzCbrN&q=85&s=aadadb67eab561dfe76ff0a99d20e9eb" alt="Nevermined Payment Flow" width="754" height="860" data-path="images/payment-flow.png" />

<Steps>
  <Step title="Register your API">
    Any HTTP endpoint your agent exposes. Nevermined gates access at the request level - if a caller isn't entitled, they get a 402 before your code even runs.
  </Step>

  <Step title="Create a payment plan">
    * **Payment method** - Fiat ([cards](/docs/products/payments/overview)) or crypto (USDC)
    * **Pricing model** - Fixed per call, or dynamic (builder-defined or cost+margin)
    * **Plan type** - Prepaid (users buy a plan upfront) or pay-as-you-go (charge per request)
  </Step>

  <Step title="Validate, deliver, settle">
    Entitled? Deliver and settle. Not entitled? Return **402 Payment Required**.
  </Step>
</Steps>

**Builders** register API endpoints, set pricing per call, and receive payouts. Add a few lines of validation to your server.

**Users** purchase a plan (fiat or crypto) or go pay-as-you-go. No human in the loop.

## Integration Options

Nevermined is framework-agnostic. It works with LangChain, CrewAI, Strands, OpenAI Agents, or plain HTTP.

* **Code-first** - TypeScript and Python SDKs, REST API, and CLI for full programmatic control
* **[Nevermined App](https://nevermined.app)** - Card enrollment (Visa / Stripe / Braintree) and spending delegation management

### Merchant Onboarding

Use the [Nevermined App](https://nevermined.app) for reporting, analytics, and plan management. To receive fiat payouts, connect a Stripe Connect account there. Stablecoin payouts settle directly to your wallet.
