x402 Payment Proxies
Transform any API into a pay-per-use service or seamlessly access existing x402-gated resources through automatic payment proxies.
How x402 Proxies Work
x402 Payment Proxies create intelligent middleware between your applications and APIs, automatically handling micropayments for resource access. Whether you're consuming existing x402-gated services or creating new payment-gated endpoints, these proxies handle the complexity of authentication, payment processing, and access control.
Consume x402 Resources
Use your Emblem Auth login or your users' authenticated vaults to automatically pay for access to existing x402-protected APIs and services.
Gate Your APIs
Transform any internal or external API into a pay-per-use service, creating new revenue streams from your existing infrastructure.
Use Cases
Internal Service Monetization
Gate Premium Features
Create tiered access to your internal services. Let users automatically pay small amounts to access premium features, advanced analytics, or computational resources.
Usage-Based Billing
Transform fixed-cost internal tools into pay-per-use services. Perfect for expensive operations like AI inference, image processing, or data analysis.
Agent & AI Tool Access
Pay-Per-Tool AI Agents
Give your AI agents access to paid tools and services. Users pay automatically when their agents use expensive resources like real-time data feeds, premium APIs, or computational services.
Authenticated Tool Access
Seamlessly provide authenticated users access to external paid services using their personal vaults or a shared admin vault for team resources.
External API Integration
x402 Service Consumption
Access existing x402-protected services without implementing payment logic in your application. The proxy handles authentication, payment, and retries automatically.
API Monetization
Expose your internal APIs as x402-gated services, creating new revenue streams from existing infrastructure without complex billing systems.
Authentication & Payment Sources
Admin Vault Payments
Use your organization's admin vault to pay for services on behalf of users. Perfect for providing seamless access to premium tools without requiring individual user payments.
- • Centralized billing and cost control
- • No user payment setup required
- • Ideal for team tools and internal services
User Vault Payments
Enable authenticated users to pay from their personal Emblem vaults. Users maintain control over their spending while getting seamless access to paid services.
- • User-controlled spending
- • Personal wallet integration
- • Transparent payment tracking
