Two deliberately separated datasets

Two deliberately separated datasets. (1) PRICE/COST LAYER: end-to-end trade pricing across 67 Nigerian markets for 8 staples, built from three labelled layers — World Bank Real-Time Food Prices (model-estimated, monthly, back to 2007), WFP market monitoring (enumerator-observed, monthly rotating, plus a Kenya layer), and Lokoja's own weekly field ambassadors. Crucially it prices the trade, not just the commodity: corridor spreads quoted NET OF HAULAGE using a fixed loading cost plus per-tonne-km trucking rates calibrated from working Nigerian transporters, corrected for road circuity and indexed weekly to the national diesel price, with unviable spreads suppressed and conflict corridors excluded rather than priced as if safe. The ambassador layer is genuinely proprietary — contracted insiders at Dawanau (Kano), Mile 12 (Lagos) and Onitsha Main Market filing structured weekly reports under a personal-observation declaration covering per-bag prices in trader units, supply levels, diesel and pump prices, real transport quotes, market disruptions and trader counts. (2) DEMAND-SIGNAL LAYER: every WhatsApp assistant question logged as a structured, time-stamped record — commodity, location, trade size, language.

Dataset card

Type: not stated
Format: Tabular time-series with explicit layer provenance and nature labels (model-estimated versus observed), delivered through free web and a free API, in trader units (50kg/100kg bags, lorry loads) alongside tonnes; plus structured event records for the WhatsApp demand-signal stream
Volume: Stated: 67 Nigerian markets x 8 staples with continuous coverage back to 2007 on the World Bank layer (~19 years), plus monthly rotating WFP observations, plus weekly ambassador reports from 3 markets, plus a transport-cost and corridor-spread layer over the published corridors. The long-run price panel is therefore substantial (tens of thousands of market-month observations), while the genuinely proprietary layers are thinner — weekly ambassador series from 3 markets to date, and a demand-signal log the operator concedes is only weeks-deep.
Users: Est. low thousands of WhatsApp-assistant contacts (inference: access is free web and a free API with no signup gate described, so registered accounts are not the meaningful denominator; the demand-signal corpus volume is the observable proxy, and the operator states it is only weeks-deep, implying an early but active query base)
History: 19 years
Update frequency: not stated
Growth: Active with a stated expansion plan — the methodology page is dated 'Updated week of 24 August 2026' and states that ambassador expansion is ranked by information value, with the sell-side and buy-side of published corridors getting ambassadors first; a Kenya layer already exists at lokoja.app/ke
Launched: est. 2025-2026 as a standalone product — the price series it republishes reach back to 2007 but those are upstream World Bank and WFP layers; Lokoja's own construction is recent, and its demand-signal corpus is self-described as weeks-deep. No copyright year or launch date is stated.
