API Development Services

Our first consultation is free. We’ll evaluate your needs and provide a roadmap or estimate at no charge.

Yes, we build both public APIs that let outside apps or services connect with your platform, and private APIs that are used inside your company to keep systems working smoothly and data secure.

Yes, we can help with single API builds, integrating different systems, and smaller projects.

Yes, we give you clear, detailed prices, so you'll always know what you're paying for.

Yes, we modernize old APIs, making them perform better and meet today's standards.

We understand your project is confidential, and we're always ready to sign Non-Disclosure Agreements (NDAs) to protect your information and ideas.

With TechAhead, you get a complete team of expert developers, testers, architects, and project managers to ensure quality, speed, accountability, and ongoing support.

Basic REST APIs with standard CRUD operations start around $15K-$25K and take 6-8 weeks. Complex enterprise APIs with microservices architecture, OAuth authentication, and multiple third-party integrations run $50K-$100K over 12-16 weeks. Timeline depends on endpoint complexity and documentation requirements.

Not at all. We've got backend specialists across the world who collaborate on shared code repos and maintain 24/7 development cycles. Your APIs get built faster because work continues around the clock, and you get a single point of contact for all technical discussions.

We build compliance into the API from day one. That means OAuth 2.0 and JWT tokens for authentication, encrypted data transmission, rate limiting to prevent abuse, and full audit trails. We handle GDPR data handling, HIPAA for healthcare, PCI-DSS for payments, and SOC 2 for enterprise clients.

Week 1-2: We map out all endpoints, data models, and authentication flows. Week 3-6: Core development with iterative testing using Postman. Week 7-8: Security hardening, load testing, and documentation. You get Swagger docs, SDK samples, and sandbox access throughout. We deploy to staging first, then production after your sign-off.
