Weather and air quality on VM0
Conditions now, the forecast ahead, what just happened, and the air quality, for anywhere you need it. Currently free.
Location & weather · No setup · Recorded for usage analytics, currently 0 credits
Weather feeds more work than people expect: site visits, deliveries, events, retail, construction, and anything where an outdoor day is worth more than an indoor one.
An agent can read current conditions, the hourly and daily forecast, what the weather actually did over the last few days, and the current air quality. It comes from Google, and calls are currently free, which makes it the easy thing to add to any workflow where conditions change the plan.
What Weather and air quality is
Most plans have weather in them somewhere, and the useful question is rarely just the temperature. It is whether Thursday still works, or whether the number that moved last week moved because of the rain.
The service covers conditions right now, forecasts by the hour and by the day out to about ten days, the recent past, and current air quality, for wherever you point it.
Every one of those is a single call made and paid for by VM0. Calls are recorded so you can see the usage, and they currently cost nothing.
People generally search for a free weather API and find that free still means an account, a key and a request limit somebody has to watch. This has none of those, and calls currently cost nothing, which is a different kind of free.
What Weather and air quality can do
What an agent can do with it, and what comes back when it does.
Coverage and limits
What it does not do, said up front, so nobody plans a workflow around something that is out of scope.
It works from a location, not a place name
The lookup needs a precise location, so a city or address is turned into one first. In practice that is the maps service doing one step earlier in the same workflow.
Ten days ahead, not a season
Forecasts run hours and days ahead, up to about ten. Anything further out is a different kind of question and a different kind of source.
The recent past, not the climate record
History covers the last few days, which is what explains something that just happened. Long-run climate series come from a climate archive instead.
Free today, not promised forever
Calls currently cost 0 credits and are recorded so the usage is visible. Treat that as today's price rather than a permanent guarantee.
What Weather and air quality costs
Web services are billed in credits per call, not per token. There is no separate vendor bill to reconcile.
zero weatherWeather calls are recorded so you can see them and currently cost 0 credits. There is no account, no free-tier quota to blow through and no key. If checking conditions would make a workflow better, there is no cost argument against it.
Setup and access
Nothing to set up
Nothing to connect. No weather signup, no key, no plan. An agent can pull a forecast on its first run.
Who can use it
Weather is a permission granted per person and per agent. It is the least sensitive service here, but it is still something you hand out rather than something every agent holds by default.
What teams use Weather and air quality for
Deciding whether the plan survives the week
A daily brief checks the forecast for the sites or cities that matter and flags only the days where conditions change what someone had planned to do.
Explaining a number that moved
Footfall, delivery times or energy use that looks odd is often just the weather. Pulling the last few days alongside the metric answers the question before anyone opens a dashboard.
Air quality as an operational input
For outdoor work, events, or an audience with health concerns, current air quality is the difference between going ahead and moving indoors.
When not to use Weather and air quality
Skip it for long-run climate analysis, which needs a climate archive rather than the last few days. And skip it for severe-weather warnings, where the national meteorological service is the responsible source and the only one worth acting on.
What this is called elsewhere
The same thing goes by several names in the market. If you have shopped for one of these, this is how it maps to what you get here.
Free weather API
What people are usually looking for. Calls here currently cost 0 credits and there is nothing to sign up for, so there is no request limit of yours to exceed.
Weather forecast API
Hourly and daily forecasts out to about ten days, which covers the operational question of whether this week's plan still works.
Historical weather
What the weather actually did over the last few days, which is what explains a number that just moved. It is not a climate archive.
Air quality API
Current air quality for the same place as the forecast, which for outdoor work and events matters more than the temperature.
Weather without an API key
No signup, no key and no plan. An agent can pull a forecast on its first run, which is why it is easy to add to a workflow that only sometimes needs it.
Weather and air quality compared
Weather and air quality vs your own weather API key
Weather data is cheap and still costs you a signup, a key, a free-tier limit and someone to notice when it is exceeded. This has none of those and currently charges nothing.
Weather and air quality vs reading a weather site
Reading a forecast page costs more than the weather call itself and breaks whenever the page changes. There is no reason to do it.
Weather and air quality vs an official meteorological service
National services are the right source for warnings and for anything regulated. This is the right source for the everyday operational question of what the weather will be.
The short version
The cheapest useful call on the platform, and currently free. Let conditions inform the plan in any workflow where they actually matter.
Frequently asked questions
Do I need a weather API key?
No. VM0 calls the provider on your behalf. There is no account, key or plan on your side.
Can I just give it a city name?
Yes, in a request. The lookup itself needs a precise location, so the agent turns the city into one first using the maps service.
How far ahead does the forecast go?
Hour by hour for the near term, and day by day out to about ten days.
How far back does history go?
The last few days, which is what explains a number that just moved. Long climate series need a dedicated archive.
Does it include air quality?
Yes. Current air quality is available for the same place as the forecast.
Is this really a free weather API?
Calls currently cost 0 credits and are recorded so the usage stays visible. That is today's price rather than a permanent promise, and there is no account or key either way.
How does it compare with a free weather service I sign up for?
Services like those are cheap and still cost you a signup, a key, a request limit and someone to notice when it is exceeded. Here there is nothing to set up and nothing to watch.
Can it warn me about severe weather?
It can tell you what the forecast says, and it should not be the thing a warning system depends on. For warnings, the national meteorological service is the responsible source.
How you ask for Weather and air quality
You describe what you want in plain language. The agent works out which service it needs and makes the calls.
“Give me the ten-day forecast and current air quality for Beijing, and tell me which days are best for outdoor work.”
“Our footfall dropped last Thursday. Check the weather that day at each site and tell me if that explains it.”
“In the morning brief, flag any site where the forecast changes what the team planned to do.”
