Analyzed data, not raw rows.
Research-ready, point-in-time panels over African & emerging-market data — demand signals, factors and surprises — each with provenance on every value and as_of semantics for clean, no-look-ahead backtests. Plug-and-play via API, MCP, the certvas SDK and bulk Parquet.
Published for research and informational use. Not administered as, and not for use as, a regulated benchmark.
Procurement-Demand Signal
Government contract flow as a leading demand read: category demand share, buyer concentration and 3-month momentum, point-in-time. Built on AF-TENDER (OCDS).
Use it to: spot sectors where public demand is rotating in, ahead of the listed suppliers who serve them.
Methodology, schema & download →Fundamentals-Factors Signal
Point-in-time quant factors for listed African issuers — net margin, ROE, ROA, asset turnover, equity ratio and growth — from as-reported values, no look-ahead. Built on AF-FUND.
Methodology, schema & download →Revision-Surprise Signal
Restatement magnitude — how much a filed figure was later revised — across point-in-time vintages. A genuine earnings-quality read, unique to Certvas's vintage archive.
Methodology, schema & download →Issuer-Persistence Signal
Lindy-style longevity from observed history — how long each issuer has been continuously reporting, how many years inside that span it actually filed, and its longest gap. No market data, no estimates, no projections.
Methodology, schema & download →Macro-Momentum Signal
Point-in-time momentum for African macro series — daily FX and monthly CPI across five core markets — 1- and 3-period change, latest-vintage per date, no look-ahead. Built on AF-MACRO.
Methodology, schema & download →Supplier-Issuer Demand Signal
Government tender award flow mapped through the entity-resolution spine to a canonical issuer — who is winning public spending, buyer concentration and resolution confidence, point-in-time. Built on AF-TENDER × the spine.
Methodology, schema & download →Tender-Award Concentration Signal
How competitive each slice of public procurement really is — supplier HHI by award value and count, top-supplier share, effective number of suppliers and the repeat-winner rate, per country, category and month. Built on AF-TENDER (OCDS).
Use it to: screen for single-source and capture risk, and to size how contested a category is before pricing into it.
Methodology, schema & download →Fundamentals Quality Signal
Not how big the profit is — how real it is. Accrual ratio, cash conversion, trailing margin volatility and restatement intensity per issuer × fiscal year, from as-reported values with no look-ahead. Built on AF-FUND.
Use it to: separate cash-backed earnings from accrual-heavy ones before trusting a profitability screen.
Methodology, schema & download →SOE-Procurement Signal
State and parastatal buyers resolved to the entity spine — tender flow, supplier count and supplier concentration per public body. Buyer-side by design: that is the direction the spine actually resolves.

One schema and one provenance envelope across the REST API, MCP server, certvas SDK, Snowflake and bulk Parquet. Coverage deepens as more license-clean sources clear the register.
