Section 1

Introduction & Capabilities

Welcome to the Tender Procure Distribution API. This API provides programmatic access to a comprehensive, continually updated database of Indian government tenders, concluded bid results (Award of Contract records), BOQ item specifications, criteria, exemptions, and origin documents.

Engineered with an ID-first query pipeline and an in-memory caching engine, the API delivers fast response times for client dashboards, automatic alert pipelines, and internal ERP procurement integrations.

Base URL & Environments

All requests must target the production endpoint over HTTPS:

Section 2

Authentication & Security Scopes

Every request (except the public /health endpoint) must include two authentication headers. The server verifies both credentials on each request; invalid or missing credentials return HTTP 401 Unauthorized.

Header	Type	Required	Description
X-API-Key	string	Required	Your unique client API key.
X-API-Secret	string	Required	Your confidential API secret key. Verified using timing-safe comparison.

Security Requirement: Never expose your API credentials in browser-side code or public repositories. Store them as environment variables on your backend server and proxy calls to Tender Procure.

IP & Domain Whitelisting

Client keys can optionally be restricted to specific server IP addresses or authorized Origin domains. Calls from non-whitelisted sources return 403 Forbidden.

Keyword & State Scoping

If your client key has configured state boundaries (allowed_states) or keyword boundaries (allowed_keywords), the API automatically restricts responses accordingly.

Section 3

Rate Limits & Response Headers

The API applies a sliding 60-second window and a daily quota that resets at midnight UTC. Standard limits are 60 requests per minute and 10,000 requests per day.

Header	Type	Description
X-RateLimit-Limit-Minute	integer	Maximum requests permitted per rolling 60-second window (default: 60).
X-RateLimit-Remaining-Minute	integer	Remaining calls available before rate throttling is enforced.
X-RateLimit-Limit-Day	integer	Maximum daily calls assigned to your license tier (default: 10,000).
X-RateLimit-Remaining-Day	integer	Calls remaining today. Resets automatically at 00:00:00 UTC.
Retry-After	integer	Returned on HTTP 429. Number of seconds to wait before repeating request.

Handling HTTP 429 (Too Many Requests)

When rate limits are exceeded, the API responds with HTTP 429 and includes a Retry-After header indicating the number of seconds to wait. We recommend using exponential backoff before retrying.

Section 4

Standard Response Envelope & Error Format

All endpoints return a consistent JSON envelope with success, a unique requestId for tracking, the response payload in data, and execution metadata in meta.
