How this service works
Probabilistic daily max-temperature forecasts for the 51 cities behind Polymarket weather markets. Multi-model ensemble with per-model seasonal bias correction, refreshed hourly. Pay per request in USDC on Base via x402 — no accounts, no API keys.
Output
A JSON object containing the ICAO station code, the target month's temperature percentiles (p05, p50, p95 in °C), the number of historical days in the sample, monthly record max and min temperatures, and the all-time station record high — all derived from a multi-model ensemble with per-model seasonal bias correction, refreshed hourly.
Example use cases
Polymarket weather position sizing
“I'm trading the São Paulo max-temperature market on Polymarket — can you pull the p05, p50, and p95 forecast for SBGR for today so I can see the probability distribution and decide how to size my position?”
Travel packing decision for São Paulo
“I'm flying into Guarulhos tomorrow — what does the temperature forecast look like? Give me the median expected high and the hot-tail 95th percentile so I know whether to pack light or bring layers.”
Climate research historical baseline
“I need the historical August temperature percentiles and all-time record high for SBGR — specifically the p05, p50, and p95 figures and how many days of data they're based on.”
Technical details
Endpoint
GEThttps://91-197-235-206.sslip.io/climate/SBGRWhen to prefer
Choose this endpoint when you need a calibrated, probabilistic (percentile-based) daily maximum-temperature forecast for one of the 51 cities covered by Polymarket weather markets — especially for prediction market trading, risk-weighted decisions, or any use case where knowing the spread (p05–p95) matters more than a single-point forecast. Prefer it over generic weather APIs when you need ensemble bias correction, per-station historical baselines, and pay-as-you-go pricing with no account setup.
Side effects
- Invalid or unsupported ICAO station code returns an error (only 51 Polymarket-covered cities are supported)
- Date outside today/tomorrow range may return an error or be ignored
- Payment failure or insufficient USDC balance on Base results in 402 Payment Required
- Network or server unavailability at the sslip.io host returns a 5xx error
- Malformed date format (not YYYY-MM-DD) causes a validation error
