Weather API Reference

Overview

Use it as a weather data API for live conditions or as a weather forecast API for the week ahead. Query either a city name or a zip code to fetch real-time atmospheric readings. Responses supply temperature, wind speed, and compass heading in both metric and imperial measurements. Paid plans add a 7-day daily forecast with highs, lows, rain chance and precipitation totals, plus precipitation amounts, barometric pressure, apparent feels-like temperatures, visibility, and wind gust speeds.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/weatherforecast

1
2

curl "https://api.apiverve.com/v1/weatherforecast?city=San%20Francisco&forecast=true" \
  -H "x-api-key: your_api_key_here"

const res = await fetch('https://api.apiverve.com/v1/weatherforecast?city=San%20Francisco&forecast=true', {
  headers: { 'x-api-key': 'your_api_key_here' },
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);

import requests

res = requests.get(
    "https://api.apiverve.com/v1/weatherforecast?city=San%20Francisco&forecast=true",
    headers={"x-api-key": "your_api_key_here"},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/weatherforecast?city=San%20Francisco&forecast=true", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Parameter	Type	Description
`city`Required	string	The city for which you want to get the current weather (e.g., San Francisco)
`forecast`Optional	boolean	Included by default. Set to false to omit the 7-day forecast and return current conditions only.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted	A key restriction or IP allow-list; see key scoping.
`429`	Rate limited, or out of credits	Read `error` to tell them apart; see rate limits.

Use cases

Delivery Route Planning: When high winds threaten courier safety, dispatch software checks live wind speeds and compass direction across delivery zones before assigning routes, and reads the coming week of forecasts to reschedule ahead of bad days.
Travel Booking Portals: Travel sites display real-time temperatures for destination cities alongside a 7-day outlook so travelers know what conditions to expect across their whole stay.
Smart Home Thermostats: Home automation platforms read outdoor temperatures for local zip codes to adjust heating and cooling cycles throughout the day.
Outdoor Event Management: Organizers monitor current wind speeds and temperatures by city to decide when to secure temporary staging, and use daily rain chance to pick a date or trigger a postponement early.
Field Service Scheduling: Dispatchers check daily rain chance and precipitation totals for the week ahead to slot outdoor jobs like roofing or landscaping onto dry days.
