The Payment Layer ForAutonomous Software
HTTPayer lets software pay software. Automated, usage-based payments over HTTP. No subscriptions. No invoices. No friction.
Backed by Circle, SKALE, and Chainlink ecosystems
Built on open standards and trusted infrastructure
Software is becoming autonomous.
Payments haven't caught up.
APIs, AI agents, and services can now act on their own
But payments are still built for humans
Traditional payment infrastructure wasn't designed for autonomous systems
Subscriptions
Monthly billing cycles designed for human customers
Manual billing
Invoice generation and payment tracking require human intervention
Accounts and API keys
Authentication systems built around user accounts
Invoices and reconciliation
Complex accounting processes need manual oversight
Autonomous software needs autonomous payments
Monetization is the bottleneck
Modern applications face critical payment infrastructure challenges
Subscriptions don't scale to machine usage
Traditional subscription models weren't designed for AI-driven consumption patterns
Usage-based pricing is expensive to build and maintain
Complex metering infrastructure requires significant engineering resources
Global payments add friction and compliance risk
Managing international transactions and regulations creates barriers
AI agents can't subscribe or manage invoices
Autonomous systems need programmatic payment capabilities
This limits adoption and blocks new business models
HTTPayer automates payments at the protocol level
HTTPayer turns HTTP 402 into a fully automated payment flow.
Any request can become a paid request, without changing how software is built.
Developers keep using HTTP.
HTTPayer handles the money.
Pay-per-request pricing by default
True usage-based pricing without infrastructure complexity
Cross-chain USDC settlement
Instant global payments without currency conversion
Built-in budgets, caps, and policies
Granular spending controls for autonomous systems
Privacy-preserving by design
Secure transactions without compromising user data

Public docs and examples
Complete guides and working code
Use Cases
Built for real revenue impact
Designed for scale and compliance
Secure key isolation and encrypted execution
Spend limits and abuse protection by default
Verifiable payment callbacks
Audit-ready by design
The future of software is pay-per-use
If software can act on its own, it should be able to pay on its own.
HTTPayer makes that possible.
