For Agents
Manage feeds, dashboards, triggers, tokens, ACLs, and webhooks across the full Adafruit IO REST surface for IoT projects.
Use for: I need to create a trigger when temperature exceeds 30C, Add a new device token for a microcontroller, Send a batch of readings into a group's feed, Build a dashboard with chart and gauge blocks
Not supported: Does not handle device firmware OTA, cellular connectivity, or paid IoT SIMs - use for Adafruit IO feeds, dashboards, triggers, tokens, ACL, and webhooks only.
Adafruit IO is the cloud service paired with Adafruit's maker hardware, used to log sensor data, build dashboards, and trigger automations from connected devices. This REST API exposes feeds, dashboards, blocks, groups, triggers, tokens, ACL, throttle status, and webhook endpoints across 71 operations. Authentication uses the X-AIO-Key header (or query parameter) and an optional X-AIO-Signature for signed requests. The /{username}/groups/{group_key}/feeds/{feed_key}/data/batch path supports batched ingest scoped to a group, and the /{username}/triggers resource lets devices fire automations based on feed values.
Install Jentic One Beta
Connect the Adafruit IO REST API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Adafruit IO REST API, 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%2Fadafruit.com%2Fadafruit-main" | sh2
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%2Fadafruit.com%2Fadafruit-main" | sh
jentic register # connects your agent to your Jentic One instanceJentic 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 Adafruit IO REST API.
Create feeds and ingest data points individually or in batches under /{username}/feeds and group-scoped /{username}/groups/{group_key}/feeds/{feed_key}/data/batch
Build IoT dashboards and add blocks via /{username}/dashboards and /{username}/dashboards/{dashboard_id}/blocks
Create triggers that fire automations on feed values via /{username}/triggers
Manage device tokens through /{username}/tokens and /{username}/tokens/{id}
Configure resource-level access control via /{username}/{type}/{type_id}/acl
Receive device telemetry through webhook endpoints at /webhooks/feed/:token and /webhooks/feed/:token/raw
Inspect throttle status with /{username}/throttle and recent activity via /{username}/activities
Use Cases
Patterns agents use Adafruit IO REST API for, with concrete tasks.
★ Trigger-based automations
Adafruit IO triggers fire when feed data crosses a threshold or matches a value, useful for hobbyist alerting (e.g. notify when humidity drops below 30%). An agent can POST to /{username}/triggers with the feed and condition, and pair the trigger output with an external notification API. This avoids polling feed values from a separate service.
POST a trigger to /{username}/triggers when the temp feed exceeds 30 and connect it to a notification webhook
Group-level batch ingest
Devices that publish multiple feeds (e.g. a weather station publishing temperature, humidity, and pressure together) can post a group-scoped batch via /{username}/groups/{group_key}/feeds/{feed_key}/data/batch. This lets the group's feeds stay in lockstep, which simplifies later analysis and dashboard rendering.
Post a 10-minute window of telemetry to /{username}/groups/weather/feeds/temp/data/batch and then to humidity
Token and ACL management for fleets
Operators of small device fleets issue per-device tokens and apply ACL rules so each device only reads or writes its own feed. /{username}/tokens manages token creation and rotation, while /{username}/{type}/{type_id}/acl applies access rules. An agent can rotate a compromised token and update ACL entries in a single workflow.
List tokens at /{username}/tokens, revoke the compromised id, create a new token, and update the ACL on the affected feed
Webhook telemetry capture
Some devices push data to Adafruit IO's webhook endpoints (e.g. /webhooks/feed/:token) rather than calling REST endpoints directly. An agent acting as the device's gateway can sign and forward payloads, and the /webhooks/feed/:token/raw variant handles non-JSON sensor payloads. This is helpful for legacy hardware or third-party trackers.
Forward a raw sensor payload to /webhooks/feed/<token>/raw and confirm the response status
AI agent integration
Makers building agent assistants for their lab or smart home expose Adafruit IO REST through Jentic alongside notification APIs. The X-AIO-Key (and signature, when used) lives in your Jentic One instance, so the agent searches by intent - 'create a trigger', 'add a dashboard block' - without seeing raw keys.
Search Jentic for 'create an Adafruit IO trigger when temp exceeds 30', load the schema, and execute it

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Adafruit IO REST API by hand means attaching the X-AIO-Key and X-AIO-Signature headers on every call and threading the username, feed key, and dashboard id through feeds, triggers, tokens, and webhooks. Through Jentic you install once, import the Adafruit IO REST API from the API Directory, store the key and signature once, and your agent calls it.
Permission scoping
Adafruit IO puts the feed key in the URL path (/{username}/feeds/{feed_key}/...), so a rule can pin your agent to one feed: it can batch data into that feed and read its chart and nothing else. You choose the operations it may call, so creating triggers or rotating tokens is not included unless you add it.
Credential isolation
Your Adafruit IO X-AIO-Key and X-AIO-Signature are stored once, encrypted, by your own Jentic One instance and injected as headers at execution time. They never enter the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'create an Adafruit IO trigger' or 'rotate a device token', and Jentic returns the matching operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Adafruit IO REST API through Jentic.
What authentication does the Adafruit IO REST API use?
The API supports an X-AIO-Key API key, in either the request header or query string, and an X-AIO-Signature header for signed requests. Through Jentic, both values are stored encrypted in your Jentic One instance and the agent receives a scoped execution handle, so the raw key and signature never appear in prompts.
Can I create triggers and tokens with the Adafruit IO REST API?
Yes. POST /{username}/triggers creates a feed-value trigger, and POST /{username}/tokens issues a per-device token. Both are useful for fleet deployments where each device needs its own credentials and event automations bound to specific feeds.
What are the rate limits for the Adafruit IO REST API?
Adafruit IO enforces a per-minute throughput cap that depends on the account tier. Use GET /{username}/throttle to read your current remaining capacity, and prefer batch ingest via /{username}/feeds/{feed_key}/data/batch or /{username}/groups/{group_key}/feeds/{feed_key}/data/batch over single-point posts.
How do I create a trigger when a feed crosses a threshold through Jentic?
Run pip install jentic, search Jentic for 'create an Adafruit IO trigger', load the schema for POST /{username}/triggers, and execute it with the feed_key, condition, and threshold value. Jentic injects the X-AIO-Key from the vault.
Does the Adafruit IO REST API support access control on feeds?
Yes. The /{username}/{type}/{type_id}/acl and /{username}/{type}/{type_id}/acl/{id} endpoints manage access control rules per resource. That lets you keep a feed writable by one device token but read-only for another or for collaborators.
Can devices push telemetry to Adafruit IO via webhooks?
Yes. /webhooks/feed/:token accepts JSON payloads and /webhooks/feed/:token/raw accepts arbitrary raw payloads, which is useful for legacy hardware or third-party trackers that cannot be easily reconfigured to call the REST endpoints directly.
Can I limit what my agent is allowed to do with the Adafruit IO REST API?
Yes. Because you self-host Jentic One, your own rules decide which operations and credentials the agent may use, and Adafruit IO puts the feed key in the URL path (/{username}/feeds/{feed_key}/...), so you can pin the agent to a single feed. You might allow it to batch data into that feed via /{username}/feeds/{feed_key}/data/batch and read its chart data while excluding everything else. Higher-impact operations like creating triggers at /{username}/triggers or rotating device tokens at /{username}/tokens stay off unless you explicitly grant them. Your X-AIO-Key and X-AIO-Signature are held by your own instance and injected at execution time, so the agent can only call the operations you scoped.
