Overview

Introduction

Primary-source financial data for the United States and India through one predictable API.

Corpus turns regulatory filings, market records, annual reports, news, and judgments into stable JSON and searchable documents.

The public API has one production origin and no version prefix:

https://corpus-api.onera.app

Country namespaces keep identifiers and data models honest:

  • /us/* uses SEC CIKs, tickers, accessions, EDGAR filings, and US financial statements.
  • /india/* uses ISINs, NSE symbols, BSE codes, annual-report artifacts, news, and court judgments.

Every response uses snake-case fields and a resource-named envelope. Collections include metadata for pagination, jurisdiction, and point-in-time reads.
