Data & measurement
Daily information has different cadences
How weather, exchange rates, fuel prices, and food observations should be read alongside their dates and units.
Refreshing a page does not update the observation date of a price series. A recent retrieval and a recent measurement are different things.
Use the source’s meaning
The current quick-conditions implementation draws on several distinct public inputs. Their update patterns and geographic scope differ; presenting them together must not flatten those differences.
- Weather
- Open-Meteo current conditions and hourly temperatures for Port-au-Prince.
- Exchange rates
- BRH reference and informal-market figures, with reference-rate history.
- Fuel
- MEF published gasoline and diesel prices. A published pump price does not establish availability at a specific station.
- Rice / black beans
- WFP price data distributed through HDX, filtered to actual Port-au-Prince observations per kilogram. These are periodic observations, not a live shop quote.
Preserve units, scope, and dates
A useful price comparison requires the same commodity, unit, market, and observation basis. Reference exchange rates should not silently become a claim about the rate offered by every merchant.
Trends should reflect actual stored or sourced observations. Missing data should remain missing; an unavailable source must not turn into a fabricated flat line.
Allow independent failure
The data sources are fetched independently. Failure to retrieve one source should not hide usable data from another. Cached data needs its original context and a visible freshness statement.
This documentation explains the implementation’s data contracts. The live analysis page currently measures public signals and recent news; it does not substitute for the app’s daily-condition tiles.
