Everything developers need to integrate, build on, and pay for your API product
Well-designed, versioned APIs following OpenAPI 3.1 specification for REST and schema-first design for GraphQL. Consistent error handling, pagination, filtering, field selection, and batch operations. Every endpoint is documented, tested, and designed for backward compatibility across versions.
A Stripe-quality developer portal with interactive API documentation, getting-started guides, code samples in multiple languages, API explorer for live testing, changelog, and status page. Developers can sign up, generate API keys, view usage, and manage their subscription without contacting your team.
Real-time usage metering that tracks API calls, compute units, data transfer, or custom metrics per customer. Tiered pricing with overage billing, prepaid credit packs, and pay-as-you-go models. Usage dashboards with alerts, invoice generation, and integration with Stripe for automated billing.
Auto-generated SDKs for Python, JavaScript, Go, Java, Ruby, and PHP from your OpenAPI spec. Each SDK includes type-safe method signatures, retry logic, error handling, and pagination helpers. Published to npm, PyPI, and Maven with semantic versioning and auto-generated documentation.
Event-driven architecture with configurable webhook subscriptions per customer. Developers register endpoints, select event types, and receive signed payloads with retry logic and delivery logs. Event replay for debugging, webhook testing tools, and dead letter queues for failed deliveries.
Intelligent rate limiting with per-key, per-endpoint, and per-plan quotas. Sliding window algorithms prevent burst abuse while allowing legitimate traffic spikes. Rate limit headers in every response tell developers their current usage and remaining quota. Automatic throttling with clear error messages.

Flexible engagement models for API platforms at any stage
"Edesy built our payment processing API from the ground up — REST endpoints, Python and JavaScript SDKs, developer portal, and usage-based billing. Developers tell us our documentation is on par with Stripe. We went from zero to 500 API integrations within six months of launch."

Founder at Payment Processing API Startup
"The metering and billing system Edesy built tracks every API call in real-time and bills customers accurately down to the individual request. Our usage-based pricing model is generating 40% more revenue than the flat-rate plans we had before because customers pay for what they actually use."

"The webhook system handles over 2 million events per day with 99.97% delivery success rate. The retry logic and dead letter queues mean no event is ever truly lost. Our customers rely on these webhooks for mission-critical workflows, and the reliability has been exceptional."
