Send a question about a location. We resolve the full context first, then pass it to Gemini for a grounded answer. Great for analysis, reports, or smart location descriptions.

Cost breakdown: 1 cr for context + 15 cr for AI = 16 cr total. Add +1 each for ?lang and ?expand.

Parameters

Param	Type	Note
cc	string	ISO 3166-1 alpha-2
lat	number	-90 to 90
lng	number	-180 to 180

Request body

Field	Type	Note
prompt	string	Required, max 500 chars

Example request

POST /interpret/CM/3.8667/11.5167
Content-Type: application/json

{ "prompt": "What is the commercial potential?" }

AI response field

"ai": {

  "response": "Yaoundé is Cameroon's political capital (pop. 2.8M). The dominant tier indicates strong commercial integration. Douala, the economic hub, is 194km SW..."
}

Device location verification using solar shadow analysis. Upload a capture and challenge data — we compute the expected sun position, analyse the visual evidence, and return a pass, fail, or inconclusive verdict on whether the device was actually at the claimed GPS location.

How it works: The sun's position is deterministic. Given a coordinate and UTC timestamp, we know exactly where shadows should fall. A user in Paris claiming to be in Douala will have shadows 10–20× too long. We analyse the device capture and compare it against the solar math.

Two modes:
Raw (this endpoint): You handle capture yourself, send one image, get the verdict. 25 credits.
Turnkey: Use POST /verify/challenge to create a challenge, redirect users to verify.bwendi.com, poll GET /verify/result/:id. We handle the camera, frame capture, and analysis. 400 credits total for the hosted flow.

Request body (multipart/form-data)

Field	Type	Required	Note
image	file	yes	JPEG only, max 1 MB
challengeId	string	yes	UUID from your server
claimedLat	number	yes	-90 to 90
claimedLng	number	yes	-180 to 180
issuedAt	string	yes	ISO 8601 UTC timestamp (server-issued)
signature	string	yes	HMAC-SHA256 of challengeId + claimedLat + claimedLng + issuedAt

Example request

curl -X POST https://api.bwendi.com/verify \

    "notes": "Very short shadows consistent with near-overhead sun."
  }
}

Verdicts

Verdict	Meaning
`pass`	Shadows are consistent with the claimed location and time.
`fail`	Shadows contradict the expected solar position — likely spoofed location.
`inconclusive`	Cannot determine — indoor photo, overcast sky, or no visible shadows.

Error responses

Status	Reason
400	Missing/invalid fields, wrong content-type, file too large, invalid signature
410	Challenge expired (90-second window)
422	Sun below horizon at claimed location/time
500	Gemini API failure

Turnkey Flow

Don't want to build the capture flow yourself? Use the turnkey flow — create a challenge, redirect users to verify.bwendi.com, and poll for the result. The hosted flow currently costs 400 credits, which is as little as 18 cents USD on the Star plan.

Step 1 — Create challenge

Field	Type	Note
lat	number	Claimed latitude (-90 to 90)
lng	number	Claimed longitude (-180 to 180)
callback	string	Optional. URL to redirect user after verification.

Example response

{
  "challengeId": "550e8400-e29b-41d4-a716-446655440000",
  "verifyUrl": "https://verify.bwendi.com/c/550e8400-e29b-41d4-a716-446655440000",

  "expiresAt": "2026-03-22T12:36:26.000Z"
}

Step 2 — Redirect user

Send your user to the verifyUrl. Append ?callback=https://yourapp.com/done to redirect back after verification.

Or embed it: <iframe src="https://verify.bwendi.com/c/UUID">

Step 3 — Poll for result

Example response (pending)

{ "challengeId": "550e8400...", "status": "pending" }

Example response (complete)

limit	int	Max results (1–100)

Query options

Param	Default	Effect
?wide=false	true	Restrict to a single big-zone cell (~11 km) instead of the default 3×3 grid (~33 km)

Response

An image/svg+xml document. Embed directly in <img src="...">, <object>, or save as .svg. Cached at the edge for 24 hours.

Returns the caller's IP-derived geolocation — coordinates, country code, city, and full country object — using Cloudflare's edge geolocation. The gateway enriches every request with x-cf-* headers before forwarding to the origin.

Coordinates are IP-based and may be inaccurate by 20–200 km depending on ISP. Use /country/:lat/:lng with device GPS for precise country resolution.
