Enterprise customers want to pull your data into their own systems.
Enterprise IT teams integrate every vendor into their data warehouse, their monitoring systems, and their internal dashboards. A public API is how they do it. Without one, your product exists as an isolated silo in their ecosystem. Adding a developer API is a standard feature of enterprise SaaS.
Enterprise or technical customer requesting API access to your product's data — to pull records, trigger actions, or integrate your product with their other systems
Enterprise customers integrate every SaaS tool into their data infrastructure. When they ask for API access, they typically want one or more of:
Read access to records. Pull customer data, orders, or transactions into their data warehouse (Snowflake, BigQuery). Used for company-wide reporting.
Write access to trigger actions. Create records via API when something happens in their system. Sync users when the HR system provisions them; create orders when their ERP processes one.
Webhook subscriptions. Receive events pushed from your application when something changes. Instead of polling your API, they receive events.
The API requirements from enterprise customers:
Authentication: API keys, scoped by permission level. Not user session tokens. Key management UI in the customer's dashboard.
Rate limiting: Protect your infrastructure. Typically 100-1000 requests/minute. Documented rate limit headers.
Documentation: OpenAPI / Swagger spec. Enterprise developers won't use an undocumented API.
Versioning: /v1/ prefix. Promise not to break /v1/ endpoints when /v2/ launches.
Pagination: Cursor-based or offset pagination for list endpoints. Required for large data sets.
The implementation:
API keys stored as hashed values in the database. Middleware to authenticate and rate-limit requests. OpenAPI spec generated from the route definitions (Zod + typed routes). Documentation hosted at /api-docs or via Swagger UI.
Public REST API with authentication (API keys), rate limiting, comprehensive documentation, and the endpoints the customer needs to complete their integration

One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.
Public REST API with authentication (API keys), rate limiting, comprehensive documentation, and the endpoints the customer needs to complete their integration
Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
API scope is defined by the endpoints the customer needs. Scoped and priced per the endpoint set.
Questions, answered.
For external APIs consumed by enterprise customers with diverse technical stacks, REST is better understood. GraphQL is more complex to consume. REST is the better default for public APIs.
Version the API from the start (`/v1/`). Never remove or change the shape of v1 endpoints; add new endpoints or a v2 for breaking changes.
