Pay-per-call pollen forecast via Google Maps Pollen API, settled on Tempo L2.
What it does
This MPP (Micropayment Protocol) endpoint proxies the Google Maps Pollen API's forecast lookup through Tempo's payment layer. Each call returns pollen forecast data for a given location, covering pollen types, levels, and related health information. The endpoint is live and responds with a 402 payment challenge, indicating it uses the "charge" intent (one-shot payment per request) settled via the Tempo method on chain ID 4217.
The underlying Google Maps Pollen API (v1/forecast:lookup) typically accepts location coordinates and returns daily pollen forecasts including pollen index values, predominant pollen types (grass, tree, weed), and health recommendations. The MPP wrapper adds a payment gate: callers must satisfy the 402 challenge by submitting a valid payment proof before the request is forwarded to Google's backend.
Pricing is 10,000 base units of the token at contract address 0x20c0…8b50 on chain 4217 (Tempo L2). Assuming this is pathUSD with 6 decimals, the cost is $0.01 per call. The provider covers gas fees (feePayer: true). No OpenAPI schema or documentation pages were found on the provider's domain; all auxiliary routes return 404. The endpoint path and description are the primary sources of information about functionality.
Capabilities
Use cases
- —Retrieve daily pollen forecasts for a specific latitude/longitude to power allergy alert apps
- —Integrate pollen data into health and wellness platforms for personalized recommendations
- —Augment weather dashboards with pollen type breakdowns (grass, tree, weed)
- —Enable AI agents to autonomously query pollen conditions and pay per request
Fit
Best for
- —Agents or apps needing on-demand pollen forecasts without managing Google API keys
- —Micropayment-native workflows that settle on Tempo L2
- —Developers who want pay-per-call access to Google Maps Pollen data without subscription commitments
Not for
- —High-volume batch pollen data retrieval where a direct Google Maps API key would be cheaper
- —Use cases requiring historical pollen data (this endpoint appears to serve forecasts only)
- —Users without a Tempo L2 wallet or pathUSD balance
Quick start
curl -X GET "https://googlemaps.mpp.tempo.xyz/pollen/v1/forecast:lookup?location.longitude=-122.08&location.latitude=37.42&days=3" \
-H "Authorization: Payment <tempo-payment-proof>"Endpoint
Quality
The endpoint is live (402 challenge captured) and pricing is parseable, but there is no OpenAPI schema, no documentation, and no example request/response available from the provider. Functionality is inferred from the endpoint path and the known Google Maps Pollen API. This is effectively a stub listing.
Warnings
- —No OpenAPI schema or documentation found on the provider domain; all doc routes return 404.
- —Currency contract address 0x20c0…8b50 on chain 4217 is assumed to be pathUSD (6 decimals) but could not be independently verified.
- —Request and response schemas are inferred from the upstream Google Maps Pollen API and are not confirmed by the provider.
- —No examples of successful responses are available.
