Forward & Reverse Geocoding
Resolve a location or address query to current place candidates and coordinates through Open-Meteo.
Preview request
The preview path is rate-limited and does not charge. It executes the live source and returns the paid response shape while withholding decision-ready values. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
curl --request GET \ "https://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/geocoding?preview=true&address=Mountain+View%2C+CA"
Input contract
| Parameter | Type | Required | Description |
|---|---|---|---|
address | string | No | Address to convert to coordinates. |
lat | number | No | Latitude for reverse geocoding. |
lng | number | No | Longitude for reverse geocoding. |
Example deliverable
This is the documented response shape, not a promise that live values will match the example. The paid request returns current or declared-source results using the same contract.

}Purchase decision
Buy when: the active task needs this product's structured result, its declared source and freshness are sufficient, and 0.01 USDC is within the buyer's authorized per-request limit.
Skip when: a cached result is sufficient, the source or fields do not satisfy the task, or the buyer has not authorized payment. Do not bypass wallet, budget, or user-approval policy.
Guaranteed response metadata
Every successful product response identifies how the result was produced. Product-specific output fields are documented in the paid OpenAPI contract. The preview proves the live source and field types without returning the paid values.
