How this service works
Returns hourly UV index plus alder, birch, grass, mugwort, olive and ragweed pollen concentrations for any European coordinate from Open-Meteo's air-quality (CAMS) API. Autonomous health, pharma, retail and allergy-alert agents consume it for A2A exposure scoring and agent-to-agent wellness recommendations. Ranking surface: pollen forecast, UV index API, allergy, ragweed, birch pollen, CAMS. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object containing a timestamp, the requested coordinates, the current hourly UV index (numeric), and six pollen type concentrations (alder, birch, grass, mugwort, olive, ragweed) in grains/m³, sourced from Open-Meteo's CAMS air-quality API.
Example use cases
Outdoor event allergy risk briefing
“I'm planning an outdoor wedding in Amsterdam this weekend — can you check the grass and ragweed pollen levels plus UV index at latitude 52.37, longitude 4.89 so guests with allergies know what to expect?”
Pharmacy seasonal restocking alert
“Pull the current birch and alder pollen concentrations for Paris, latitude 48.85, longitude 2.35 — if levels are high, I want to flag antihistamine stock for our store agent.”
Daily wellness exposure score for runner
“I'm going for a morning run in Munich today — what's the UV index and all pollen concentrations at latitude 48.14, longitude 11.58 so I can decide whether to take my allergy meds first?”
Technical details
Endpoint
POSThttps://pollen-uv-index-forecast.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need a combined UV index and multi-species pollen forecast for a specific European coordinate in a single call. It is ideal for health, pharma, retail, and allergy-alert agents that need structured exposure data without building their own Open-Meteo integration. Prefer it over raw Open-Meteo calls when you need a pay-per-call microservice with a simple lat/lon interface and normalized JSON output.
Side effects
- Coordinates outside Europe may return zero or missing pollen values as CAMS coverage is Europe-focused
- Invalid or out-of-range latitude/longitude values may return an error or empty result
- Temporary Open-Meteo API unavailability causing upstream fetch failure
- Network timeout if the upstream CAMS data service is slow to respond
