Custom API development is not a side service — it’s a core part of what we do. We’ve delivered custom integrations for fintech compliance workflows, logistics data pipelines, government data aggregators, and enterprise internal tools. We scope, build, test, host, and support every custom solution we create.

FAQ
Common Questions About Our API Services
Everything you need to know before integrating. Don’t see your question? Contact us directly — we reply within 4 hours.
What is an API service provider?
An API service provider is a company that builds, hosts, and maintains Application Programming Interfaces (APIs) that other businesses can integrate into their own products. API Express provides 10+ ready-to-use APIs covering verification, real-time data, recharge, and more — all accessible through a single platform and API key. Rather than building your own data infrastructure, you integrate once and get reliable, continuously maintained access to the data your business needs.
How do your APIs work?
All API Express APIs are RESTful and return clean JSON responses. You send an HTTPS request to our endpoint with your API key in the header and the required parameters in the query string or request body. We process the request, query the relevant data source in real time, and return a structured JSON response — typically within 100 milliseconds. Every API comes with full documentation, code samples in multiple languages, and a sandbox environment for testing before you go live.
Are your APIs secure?
Yes. Security is built into every layer of our platform. All API requests are authenticated using unique API keys transmitted over HTTPS with TLS 1.3 encryption. We support IP whitelisting and role-based access controls on enterprise plans. All data is processed within Indian data centres, and we do not store sensitive query data beyond what is required for audit logging. Our infrastructure is monitored 24/7 for anomalous access patterns and potential security incidents.
How can I integrate your APIs into my application?
Integration is straightforward. Sign up for a free account and receive your API key instantly. Then explore the API documentation for the service you need — each API has a complete reference with request parameters, response schema, error codes, and copy-paste code examples in Node.js, Python, PHP, and cURL. Use our sandbox environment to test before switching to production. Most developers complete their first live integration within one business day. Our technical support team is available to assist with any integration queries.
What is your API uptime and reliability?
API Express maintains a 99.9% uptime SLA across all API endpoints. Our infrastructure runs on redundant, auto-scaling servers hosted in Indian data centres with continuous health monitoring and automated failover. We maintain a public status page where you can view real-time system status and historical uptime data for every API in our catalogue. If an incident occurs, we communicate proactively through our status page and email notifications.
How is your API pricing structured?
API Express uses pay-as-you-go pricing — you pay only for the API calls you make, with no minimum commitment. Your first 1,000 API calls are completely free and no credit card is required to start. We also offer monthly subscription plans with volume-based pricing for businesses with predictable usage, and custom enterprise pricing for high-volume clients. Pricing is transparent — there are no hidden fees, no setup charges, and no lock-in contracts. You can view full pricing details on our pricing page or contact us for a custom quote.
