    Cadeias Cafe KcBrazilayer Causal Chains

    Causal chain for arabica coffee: minimum temperature forecast 72h ahead over the southern Minas belt (frost is the event that historically moves KC hardest, operational threshold 3 °C) → consecutive dry days stressing flowering → observed rainfall → the official BRL/USD rate that converts the international price for the grower. Brazil is the top arabica exporter. Physical signal only: bring your own price. Free sample, no payment: https://api.brazilayer.com/v1/cadeias/amostra

    Cadeias Capital BrBrazilayer Causal Chains

    Causal chain for Brazilian capital flight pressure: the live premium paid for USDT over the official central-bank rate (leads perceived FX stress by hours to days) → where institutional money actually moved, net flows into fixed income versus equities across the R$ 13.8tn fund industry → the official PTAX rate. Two independent signals, one reading: are locals paying up for dollars while funds turn defensive? Free sample, no payment: https://api.brazilayer.com/v1/cadeias/amostra

    Cadeias Energia BrBrazilayer Causal Chains

    Causal chain for Brazilian power risk: forecast rainfall over the Southeast/South (leads reservoir levels by ~2-4 weeks) → stored hydro energy per subsystem and its 7-day slope, from the grid operator → likelihood of thermal dispatch and cost pressure. Brazil runs on hydro: this is the upstream of industrial energy cost, and the rule and its limits travel in the response. Free sample, no payment: https://api.brazilayer.com/v1/cadeias/amostra

    Cadeias Soja ZsBrazilayer Causal Chains

    Causal chain for soybeans: consecutive dry days in the Mato Grosso belt (leads yield and shipped volume by months) → forecast rainfall in MT and the South → soybean volume actually exported last month from the official trade registry → year-over-year change. Brazil is the largest soybean exporter; this is the physical and trade side of global supply, not a price feed. Free sample, no payment: https://api.brazilayer.com/v1/cadeias/amostra

How these numbers are made

Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
