Facilitator
We’re entering a new era of how the internet pays for services. Instead of locking users into subscriptions or complicated payment gateways, the recently released x402 standard by Coinbase introduces a frictionless per-request payment model built for APIs, AI agents, and automated services. No more monthly billing cycles, no more over or under-usage. Just instant, trustless, on-chain micropayments with every request.
As a long-term infrastructure builder in the agentic-space, we’re excited to announce the official launch of the AltLayer x402 Facilitator, an easy plug-in payments-infrastructure layer built to simplify and streamline how your application, API or agent can accept micropayments with minimal friction.
Accessible now at facilitator.altlayer.io, the x402 Facilitator empowers developers to replace traditional payment rails with a streamlined system that charges exactly when and only when your service is used.
What is the AltLayer x402 Facilitator?
The x402 protocol is a new standard for “per-request” HTTP payments: clients attach a signed payment payload, the server verifies it, and settlement happens on-chain.
The AltLayer Facilitator (accessible at https://facilitator.altlayer.io/) is a hosted service that abstracts away the blockchain complexity and is responsible for :
Verifying payments: Confirm that the client's payment payload meets the server's declared payment requirements.
Settling payments: Submit validated payments to the blockchain and monitor for confirmation.
Providing responses: Return verification and settlement results to the server, allowing the server to decide whether to fulfill the client's request.
A facilitator takes away the pain of payment verification, settlement, and other chain-specific quirks, so that your application or service can accept payments without the need to build any custom logic.
Key benefits include:
Quick integration: One endpoint, minimal setup.
Multi-chain readiness : Use the same flow across different blockchain networks.
Focus on your product: Let the Facilitator handle payments so you focus on your service or API.
Built for the new economy: Micropayments, AI agents, developer APIs, per-use billing models.
Why this matters
In traditional payment models we often see subscriptions, large-ticket checkouts, heavy infrastructure, and cumbersome user flows. The x402 approach flips that for the modern web/agent economy:
Payments can be embedded directly into HTTP flows (e.g., an API call or agent request).
No need for heavy wallet management on the client side.
Enables true pay-per-use monetisation: one API call, one micropayment.
Helps developers serve the emerging use-cases: AI agents, automated services, on-demand workflows.
For the AltLayer ecosystem specifically, this aligns with its mission of making the web-native economy more seamless and composable.
How to Get Started
Here’s a simple onboarding path:
Visit https://facilitator.altlayer.io/ and follow the integration instructions.
Configure your service endpoint to point to the Facilitator URL.
Define your pricing logic: for example, how much each request costs, in which token, and what the network/asset is.
On the client side, make an HTTP request; if payment is required the Facilitator handles the payload verification and settlement.
Once payment is settled, you fulfil the request as normal.
Because the Facilitator abstracts away RPC nodes, signature verification and chain-specific settlement, you don’t need to become a blockchain infrastructure expert.
Use Cases & Who This Is For
Developer APIs: charge per call instead of subscription tiers.
AI-agent services: agents can pay on behalf of users for data, compute, or API access.
Web2 → Web3 hybrid services: add crypto-native payments with minimal disturbance to your existing stack.
Micropayment flows: think “pay for each request” rather than large upfront invoices.
What’s Next & Invitation to the Community
We’re just at the beginning. As adoption grows, we'll be expanding:
Supported assets / stablecoins
Additional chains/networks
SDKs, code samples, best-practices for middleware
Dashboards and analytics for payment flows
Community-driven feedback and feature requests
Invitation: If you’re a developer, service provider, or building an agent-driven product—give the Facilitator a spin. Provide your feedback, tell us what works (and what doesn’t). Your input helps shape the next-gen payment infrastructure.
