Data you can cite.
Structured company fundamentals, public-tender and macro records for the markets incumbents skip — where every value carries its source document, license class and observation time.
Start with a free, fully-provenanced sample — validate the citations before you buy.
// every value ships with its provenance { "dataco_id": "DC4C096C…", "line_item": "revenue", "value_reported": 152686973000, "currency_reported": "NGN", "period_end": "2025-12-31", "period_type": "FY", "source_ref": "S009:NASCON-FS.pdf#p12", "license_class": "S009", "observed_at": "2026-07-21T09:14Z" }
Grounding data your product can defend.
Retrieval and agent pipelines are only as trustworthy as the data under them. Every Certvas value is traceable, point-in-time, and license-checked before it ever ships.
Provenance, per value
Every row carries source_ref, observed_at and a license_class traced to a public License Register. Nothing is unattributed.
Point-in-time
Fundamentals are keyed by period_end and period_type (FY / H1 / Qn) — query a company as it reported, not as later restated.
Organizations only
Published tables contain no natural-person data — a structural rule enforced in the model layer and checked in CI, not a promise.
Measured, not claimed
Each product ships a metrics.json of measured coverage and freshness — the same figures you can query live from the API.
Three data products, all live.
One schema discipline, one provenance model — across fundamentals, procurement and macro.
Company fundamentals
Multi-year income-statement, balance-sheet and per-share line items for listed African issuers, extracted from published filings and normalized to actual units and reporting currency.
Public procurement
Open-Contracting (OCDS) tender, award and party records with supplier, buyer and monthly analytics. Natural-person parties excluded from every published table.
Macro indicators
GDP, inflation, population and more for African & emerging-market countries from World Bank Open Data — the context layer under fundamentals and tenders, every value cited to its series.
The same gold tables, delivered three ways.
Every surface wraps each response in a provenance envelope your model can quote back to a user.
Files
Parquet + CSV with provenance, dictionary and metrics bundled in a dated, citable release.
REST API
Key-authenticated, rate-limited, OpenAPI-described — every response carries its license notice.
MCP server
Agent-native tools that return values with their source and license, so your model can cite them.
Start with a free sample.
Every tier — including the free sample — ships with the full schema, provenance annex and measured metrics. Validate the citations end-to-end, then scale to the full history.
