**Category:** Weather | **Website:** [api.weather.gov/](https://api.weather.gov/) | **Docs:** [parse.bot/marketplace/c6da160f-8ac6-441c-a9a1-37c6a3175b0f/api-weather-gov-api](https://parse.bot/marketplace/c6da160f-8ac6-441c-a9a1-37c6a3175b0f/api-weather-gov-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/national-weather-service/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get active alerts

Retrieve currently active weather alerts for a US state or territory. Returns all alerts including their severity, urgency, event type, affected area description, and actionable instructions. A single call returns all active alerts for the area.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `area` | string | Yes | 2-letter US state or territory code (e.g. 'TX', 'CA', 'CO'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/national-weather-service/get-active-alerts \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"area":"<string>"}'
```

### Get forecast

Retrieve the 7-day weather forecast for a geographic point. Resolves the lat/lon to its NWS grid and returns up to 14 half-day forecast periods with temperature, wind, precipitation probability, and narrative text. Two upstream round-trips are made (point metadata then forecast grid); latency reflects both.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `latitude` | string | Yes | Latitude in decimal degrees (e.g. '39.7456'). |
| `longitude` | string | Yes | Longitude in decimal degrees (e.g. '-104.9994'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/national-weather-service/get-forecast \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"latitude":"<string>","longitude":"<string>"}'
```

### Get observations

Retrieve the latest weather observation from the nearest station to a geographic point. Resolves lat/lon to the closest observation station and returns current conditions including temperature, wind, humidity, pressure, and visibility. Three upstream round-trips (point metadata, station list, latest observation).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `latitude` | string | Yes | Latitude in decimal degrees (e.g. '39.7456'). |
| `longitude` | string | Yes | Longitude in decimal degrees (e.g. '-104.9994'). |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/national-weather-service/get-observations \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"latitude":"<string>","longitude":"<string>"}'
```
