Frequently Asked Questions
What details are returned in GST verification?+
The API returns GSTIN status, legal business name, trade name, constitution of business, taxpayer type, nature of business activities, registration date, last update date, state jurisdiction, and principal place of address.
Is the data real-time?+
Yes, GSTIN details are verified in real time against official records.
How do I get started?+
Sign up at ekostore.app/eps, verify your identity with your PAN and address details, load your wallet to test the verification APIs live, then integrate and go live.
What is EPS?+
EPS (Eko Platform Services) is the technology arm of Eko, providing the developer tools, AI tools, and APIs that power modern fintech integration.
What are the different ways to integrate with Eko EPS?+
Integrate in whichever way suits your stack: call the REST APIs directly, use our official SDKs (JavaScript and PHP) to skip request-signing boilerplate, or let an AI coding agent build the integration using our MCP server and skills. See the Developers and AI sections for each path.
How does API authentication work?+
Each request carries your static `developer_key` header plus a per-request `secret-key` header — an HMAC-SHA256 signature of the current timestamp, keyed by your access key. The access key itself is never sent over the wire. You receive UAT keys on signup and production keys after KYC.
Is there a sandbox environment for testing?+
Yes. A full sandbox environment is available immediately on signup. You can test your integration end-to-end before going live — no commitment required.
What are the sandbox and production base URLs?+
Sandbox and production share the same paths and differ only by base URL: use https://staging.eko.in/ekoapi/v3 for UAT / Sandbox, and https://api.eko.in/ekoicici/v3 for Production. A common cause of failures is calling the sandbox/staging URL with live credentials (or vice-versa) — make sure the base URL matches the keys you are using.
Do I need to whitelist my server IP?+
Production API access may require your static public (server) IP to be whitelisted. If your calls work from Postman but fail or time out from your own server, share your static public IP with us so we can whitelist it.
What response times can I expect?+
Most verification APIs return in real time with sub-second responses, and 99th-percentile latency stays under two seconds across verification endpoints. Transaction APIs (DMT, AePS, BBPS) respond within seconds.
Can the API handle high volumes?+
Yes. The API is designed to handle large-scale volumes reliably without performance degradation.
How is API usage billed?+
Usage is billed per successful API call with no minimum commitment. Volume-based pricing tiers are available — contact our team for detailed rates.
