Pay-per-call Google Maps Place Query Autocomplete via MPP on Tempo L2
What it does
This endpoint proxies the Google Maps Place Query Autocomplete API through the Micropayment Protocol (MPP), settling payments on the Tempo L2 chain (chainId 4217). Each call returns autocomplete suggestions for a partial place query string, mirroring the behavior of the standard Google Maps `queryautocomplete/json` endpoint.
The endpoint is live and responds with a 402 Payment Required challenge using the MPP `tempo` method with `charge` intent, meaning each request is a one-shot micropayment. The price per call is 2,830 base units of the token at contract address `0x20c0…8b50` on chain 4217. Assuming this is a 6-decimal stablecoin (likely pathUSD on Tempo), the cost is approximately $0.00283 per request. The provider covers gas fees (feePayer: true).
This endpoint is part of a broader Google Maps suite hosted at `googlemaps.mpp.tempo.xyz` that advertises geocoding, directions, places, routes, tiles, weather, air quality, and more. No documentation, OpenAPI schema, or landing page was found on the provider's domain — all crawled paths returned 404. The expected request/response format is inferred from the standard Google Maps Places Query Autocomplete API.
Capabilities
Use cases
- —Adding location autocomplete to search bars in apps or agents
- —Suggesting place names as a user types a partial query
- —Building address-lookup workflows that settle via crypto micropayments
- —Integrating Google Maps autocomplete without managing API keys directly
Fit
Best for
- —AI agents needing on-demand place suggestions without API key management
- —Developers who want crypto-settled, pay-per-call access to Google Maps
- —Low-volume or bursty autocomplete queries where a subscription is overkill
Not for
- —High-volume production autocomplete where a direct Google Maps API key is cheaper
- —Use cases requiring guaranteed SLA or official Google support
- —Applications needing full Places details (this endpoint returns predictions only)

Quality
The endpoint is confirmed live via a valid 402 MPP challenge with clear pricing and settlement details. However, no documentation, OpenAPI schema, or examples are available from the provider — all crawled pages returned 404. Request/response formats are inferred from the standard Google Maps API, not confirmed by the provider.
Warnings
- —No documentation or OpenAPI schema found on the provider domain — all paths return 404
- —Currency token address 0x20c0…8b50 on chain 4217 is not a widely recognized stablecoin; the assumed 6-decimal conversion ($0.00283) may be incorrect
- —Response format is inferred from the standard Google Maps Places API and not confirmed by the provider
