Direct answer
API development cost scales with endpoint count, authentication, data validation, third-party integrations, and documentation quality. A focused backend for one product can be a short engagement; multi-partner platforms take longer.
Cost drivers
- Number of resources and write paths
- Auth model (API keys, JWT, OAuth)
- Rate limits, webhooks, and idempotency needs
- External systems (payments, WhatsApp, ERP)
- Docs, examples, and error consistency

We start from a contract draft: resources, errors, and non-functional needs. Then we implement and hand over docs your team can maintain. See API Development.
