# Send IsItWater to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### IsItWater

Determine whether a latitude/longitude coordinate is over water using the IsItWater API.

### Setup

Before making API calls, check whether the user has an API key configured:

Check if ISITWATER_API_KEY is set in the environment.
If it is not set:

Inform the user: "You need an IsItWater API key. You can get one at https://isitwater.com"
Offer to help them sign up using the browser tool — navigate to https://isitwater.com, create an account, and generate an API key from the dashboard.
Once the user has a key, guide them to configure it in ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "isitwater": {
        "apiKey": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Alternatively, the user can export the environment variable directly: export ISITWATER_API_KEY=YOUR_API_KEY_HERE

Once the key is available, proceed with the API calls below.

### Water Lookup

Check whether a coordinate is over water or land.

Endpoint: GET https://api.isitwater.com/v1/locations/water

Headers:

Authorization: Bearer $ISITWATER_API_KEY

Query Parameters:

ParameterTypeRequiredDescriptionlatnumberyesLatitude, between -90 and 90lonnumberyesLongitude, between -180 and 180

Example curl:

curl -s "https://api.isitwater.com/v1/locations/water?lat=41.7658&lon=-72.6734" \\
  -H "Authorization: Bearer $ISITWATER_API_KEY"

Example response (land):

{
  "request_id": "abc123",
  "water": false,
  "features": ["earth"],
  "latitude": "41.7658",
  "longitude": "-72.6734"
}

Example response (water):

{
  "request_id": "def456",
  "water": true,
  "features": ["earth", "ocean"],
  "latitude": "36.0",
  "longitude": "-30.0"
}

Response Fields:

FieldTypeDescriptionrequest_idstringUnique identifier for the requestwaterbooleantrue if the coordinate is over water, false if over landfeaturesstring[]Geographic features at the point — e.g. earth, ocean, lake, river, glacier, nature_reservelatitudestringThe latitude that was queriedlongitudestringThe longitude that was queried

Cost: 1 credit per lookup.

### Account Info

Check the user's account details and remaining credit balance.

Endpoint: GET https://api.isitwater.com/v1/accounts/me

Headers:

Authorization: Bearer $ISITWATER_API_KEY

Example curl:

curl -s "https://api.isitwater.com/v1/accounts/me" \\
  -H "Authorization: Bearer $ISITWATER_API_KEY"

Response Fields:

FieldTypeDescriptionidstringAccount identifiernamestringAccount namebalancenumberRemaining creditsauto_recharge_enabledbooleanWhether auto-recharge is turned on

Cost: Free (no credits consumed).

### Error Handling

Status CodeMeaningDescription200OKRequest succeeded400Bad RequestInvalid latitude or longitude values401UnauthorizedMissing or invalid API key402Payment RequiredAccount has no remaining credits

Error responses return a JSON body:

{
  "error": "description of the problem"
}

### Tips

Each water lookup costs 1 credit. Use the Account Info endpoint to check the user's balance before making many requests.
When the user provides a place name instead of coordinates (e.g. "Is the Sahara Desert water?"), geocode the location first to get lat/lon, then call the water lookup endpoint.
The features array can contain multiple overlapping values for a single point — for example, a point might return both lake and nature_reserve.
