Install Jentic One Beta

Connect the Micro Weather API (M3O) to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Micro Weather API (M3O), or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fm3o.com%2Fweather-api" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fm3o.com%2Fweather-api" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Micro Weather API (M3O) API.

Retrieve current temperature, humidity and conditions for a queried location via /weather/Now

Generate multi-day forecasts including daily highs, lows and precipitation through /weather/Forecast

Query weather by city name, postal code or latitude/longitude pair

For Agents

Look up current weather conditions and multi-day forecasts for any location worldwide via two POST endpoints from the discontinued M3O microservice.

Use for: I need to get the current temperature for a city, Retrieve a 5-day forecast for a postal code, Check whether it is currently raining at a coordinate pair, Get the wind speed and direction for an outdoor venue

Not supported: Does not handle historical weather backfill, weather alerts, air quality readings, or marine forecasts - use for current conditions and short-range forecasts only.

Use Cases

Patterns agents use Micro Weather API (M3O) API for, with concrete tasks.

★ Current Conditions Lookup

Surface a single point-in-time weather reading inside a chatbot, status page or dashboard. POST /weather/Now accepts a location string and returns temperature, humidity, condition text and wind data in one call. Suitable for lightweight integrations that need a quick weather snippet rather than a full forecast feed.

Call POST /weather/Now with location 'London, UK' and return the temperature in Celsius and the condition description

Multi-Day Forecast Generation

Drive trip planning, logistics scheduling or outdoor event prep with a forward-looking forecast. POST /weather/Forecast accepts a location plus a number of days and returns an array of daily summaries with highs, lows and precipitation chance. The endpoint is suitable for agents preparing daily briefings or itinerary recommendations.

Call POST /weather/Forecast with location 'Madrid' and days=5 to retrieve the daily highs, lows and precipitation probability

AI Agent Weather Briefing

Give an AI agent the ability to fetch and summarise weather as part of a wider workflow without managing API keys. Through Jentic the agent searches for the weather operation, loads the input schema for /weather/Now or /weather/Forecast, and executes with credentials brokered by the vault. Useful for travel agents, dispatch tools and morning briefing assistants.

Search Jentic for 'get the weather forecast', load /weather/Forecast, and execute for the user's home city for the next 3 days

Key Endpoints

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the Micro Weather API by hand means sending its API key on each POST and handling the two calls, current conditions and forecast, against the M3O host. Through Jentic you install once, import the Micro Weather API from the API Directory, store the key once, and your agent calls it.

Permission scoping

You choose which Micro Weather operations the agent may call, so you can limit it to just current conditions, just the forecast, or both. The agent only reaches the operations in the set you allow.

Credential isolation

Your M3O key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'get the current weather' or 'get a five-day forecast', and Jentic returns the matching Micro Weather operation with its input schema so the agent calls the right endpoint directly.

FAQs

Specific to using Micro Weather API (M3O) API through Jentic.

Why is there no official OpenAPI spec for Micro Weather API (M3O)?

M3O does not publish an OpenAPI specification, and the M3O platform has since been discontinued. Jentic generates and maintains this spec so AI agents and developers can call the Micro Weather API via structured tooling. It is validated against the documented surface and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Micro Weather API use?

The API uses an API key passed as a header (the apiKeyHeader scheme defined in the spec). Through Jentic the key is held in your encrypted Jentic One instance, so an agent calls /weather/Now or /weather/Forecast with a scoped token rather than handling the raw M3O credential.

How many days of forecast can the Micro Weather API return?

POST /weather/Forecast returns an array of daily summaries based on a days parameter supplied in the request body. The maximum range was capped at the M3O free-tier limit; with the platform discontinued, treat the spec as a structural reference rather than a live SLA.

What are the rate limits for the Micro Weather API?

M3O previously enforced per-key request quotas tied to plan tier, but those limits no longer apply because the platform is discontinued. The spec is preserved primarily for migration planning to a replacement weather provider.

How do I get current weather with the Micro Weather API through Jentic?

Run pip install jentic, then search for 'get the current weather' to surface POST /weather/Now, load the input schema, and execute with the location field set to a city or coordinate pair. Jentic handles the API key in the background.

Can the Micro Weather API return historical weather data?

The published spec exposes only /weather/Now and /weather/Forecast - there is no documented historical endpoint. For backfill or climatology workloads, choose an alternative provider such as Visual Crossing Weather that publishes a history endpoint.
