The first pay-per-call API marketplace built on x402. No subscriptions, no API keys, no friction—just instant payments in USDC for every request.
API Payments, Reimagined
Traditional API billing is broken. We built something better.
The Old Way
- Monthly subscriptions you don't fully use
- API keys to manage and rotate
- Complex billing with unpredictable costs
- Weeks of integration work
The Endpoints Way
- Pay only for what you use—literally per call
- No API keys needed (x402 handles auth)
- Transparent pricing, instant settlement
- 5-minute setup, start earning today
Built for the Future
Everything you need to monetize your APIs in the age of autonomous agents
Instant USDC Payments
Every API call settles in under 1 second. No invoices, no net-30, no chargebacks. Direct wallet-to-wallet USDC transfers via x402.
Built for AI Agents
Autonomous agents can discover, negotiate, and pay for APIs without human intervention. The infrastructure for the agentic economy.
Real-Time Analytics
Track every call, monitor revenue, understand usage patterns. Full visibility into your API's performance and earnings.
No Subscriptions Ever
Consumers pay per call. Providers earn per call. No monthly minimums, no unused quota, no wasted money.
x402 Protocol
Open standard for HTTP payments. Your API authenticates requests via cryptographic payment proofs. No passwords, no API keys.
Global, Permissionless
Anyone can list. Anyone can consume. No gatekeepers, no approval processes. The open marketplace for APIs.
How It Works
Whether you're providing APIs or consuming them, getting started is simple
Register Your Endpoint
Point to your existing API URL. We don't host your code—your infrastructure, your control.
Set Your Price
Choose your price per call in USDC. $0.001, $0.01, $1—you decide what your API is worth.
Start Earning
Share your endpoints.market URL. Every successful request sends USDC directly to your wallet. Instant. Automatic.
Who It's For
Endpoints.dev serves a new generation of API economy participants
For AI Agent Developers
Your agents need APIs on-demand. Weather data, translation, image generation—endpoints.market lets agents discover and pay for APIs autonomously, without pre-provisioned API keys.
For Indie Developers
Built a useful API but hate dealing with Stripe, subscriptions, and support tickets? List it on endpoints.market and earn USDC every time someone calls it. We handle payments, you focus on code.
For API Resellers
Have unused OpenAI credits? Enterprise subscriptions with spare capacity? Resell access through endpoints.market and turn sunk costs into revenue.
Powered by Modern Infrastructure
Built on cutting-edge protocols designed for the agentic economy
x402 Protocol
x402 is an open standard that adds payment capability to HTTP. When an API returns a 402 Payment Required status, x402-compatible clients automatically negotiate and complete payment. No API keys. No OAuth flows. Just cryptographic payment proofs.
Instant Settlement
Sub-second finality means payments settle before your API response arrives. Micropayments are finally viable for real-world API usage.
USDC Settlement
All payments in USDC—the world's most trusted stablecoin. No volatility, no conversion, no waiting. Your earnings are immediately usable.
