For Agents

List CMS collections, create and update items inside them, capture form submissions, and upload media assets to FastMode.

Connect the FastMode API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the FastMode 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.

Install Jentic One Beta (Self-Hosted)

Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | 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.

Use Cases

Patterns agents use FastMode API API for, with concrete tasks.

★ Programmatic Content Publishing

Editorial teams use FastMode as the headless backend for marketing sites and use the API to publish posts from external workflows. The agent reads the target collection schema, then POSTs an item to /collections/{collectionSlug}/items with the body, slug, and metadata. Replaces manual entry in the CMS UI for every published post.

POST a new blog item to /collections/blog-posts/items with title, body, and slug in the request payload

Form Submission Capture and Routing

Marketing landing pages route lead-capture form submissions into FastMode via /forms/{formName}/submit, then read them back through /forms/submissions for downstream workflows. Lets the team treat FastMode as the system of record for inbound form data without standing up a separate forms tool.

POST a form submission to /forms/contact-us/submit with the user-supplied fields, then GET /forms/submissions to confirm the entry was stored

Bulk Media Upload Pipeline

Teams migrating into FastMode use POST /media/upload to load image and document assets from another CMS or local archive. Combined with collection writes, the workflow rebuilds a content library programmatically. Saves weeks of manual upload effort during platform switches.

For each file in an export directory, POST to /media/upload with the binary, then reference the returned asset id when creating items via /collections/{collectionSlug}/items

AI Content Assistant via Jentic

Editorial agents use Jentic to call FastMode operations from natural-language prompts. The agent searches 'create a CMS item' and Jentic returns the right collection-write endpoint with its schema. The X-Api-Key credential lives in the Jentic vault, so the agent never sees the raw key and the writer can ship a working integration in under an hour.

Through Jentic, search 'create an item in a CMS collection', load POST /collections/{collectionSlug}/items, and execute with the user-drafted item payload

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

The FastMode X-Api-Key is stored encrypted in the Jentic vault. Agents call operations by intent and Jentic injects the header at execution time — the raw key never enters prompts or logs.

Intent-based discovery

Agents search 'create an item in a CMS collection' and Jentic returns the POST /collections/{collectionSlug}/items operation with its schema, so the agent does not need to browse FastMode's docs site.

Time to first call

Direct integration: 1-2 days for X-Api-Key auth, collection-slug awareness, and media upload handling. Through Jentic: under an hour — search, load, execute.

FAQs

Specific to using FastMode API API through Jentic.

What authentication does the FastMode API use?

FastMode uses an API key in the X-Api-Key header. Through Jentic the X-Api-Key is stored encrypted in the vault and injected at execution time, so the raw key never enters the agent's prompt context.

Can I create collection items with the FastMode API?

Yes. POST to /collections/{collectionSlug}/items with the item payload to create a new entry, and PUT to /collections/{collectionSlug}/items/{itemSlug} to update an existing one. The collectionSlug is whatever you defined in the FastMode workspace.

What are the rate limits for the FastMode API?

FastMode does not publish explicit rate limits in the OpenAPI spec. Treat content writes as a moderate-volume workflow, throttle bulk media uploads, and back off on 429 responses.

How do I capture a form submission through Jentic?

Install with pip install jentic, search 'submit a form response', load POST /forms/{formName}/submit, and execute with the user-supplied form fields. Sign up at https://app.jentic.com/sign-up.

Does the FastMode API support uploading binary media?

Yes. POST /media/upload accepts a binary asset and returns an identifier you can reference from item fields. Use it for images, documents, and other media that collection items need to embed.
