Install Jentic One Beta

Connect the Microlink API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Microlink 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%2Fmicrolink.io%2Fmicrolink" | 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%2Fmicrolink.io%2Fmicrolink" | 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 Microlink API.

Extract Open Graph metadata including title, description, author, publisher, image, and logo for any URL

Generate a full-page or viewport screenshot of a URL by adding the screenshot parameter

Render and download a URL as a PDF for archival or compliance purposes

Run a scripted browser action against a URL using Microlink's browser automation parameters

Use Cases

Patterns agents use Microlink API for, with concrete tasks.

★ Link Previews and Unfurls

Chat, social, and content products that show a rich preview when a user pastes a URL call GET / on api.microlink.io and use the returned title, description, image, and logo to render the card. Microlink handles redirects, lazy-loaded images, and many edge cases that a naive Open Graph parser misses, so previews look right across heterogeneous sites.

Call GET / with the URL parameter set to a news article and return the title, description, and image fields.

Automated Screenshots and PDFs

Marketing, QA, and compliance teams that need a visual record of a page at a specific moment add screenshot or pdf parameters to GET / and store the rendered artefact. This avoids running headless Chromium internally and supports authenticated pages via Microlink's browser automation parameters.

Call GET / with the URL parameter and pdf=true to capture a PDF of the target page.

Bulk URL Enrichment for Pipelines

Data teams enriching feeds of marketing or news URLs use Microlink in their ETL to attach publisher, author, and image fields to each row. Because the API is one stateless endpoint, parallelisation is straightforward, and caching by URL keeps cost bounded when the same articles reappear.

For each URL in a feed of 500 articles, call GET / and persist the returned author, publisher, and image fields.

Agent-Driven Page Understanding

AI agents that read the open web rely on consistent metadata. Through Jentic, an agent searches for the operation by intent, loads the GET / schema with the URL parameter, and executes - getting back a clean structured payload to reason over instead of raw HTML. The Microlink x-api-key never enters the agent's prompt.

Search Jentic for 'extract metadata from a URL', load GET /, and execute with the URL the user wants to research.

Key Endpoints

Why Jentic?

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

Setup

Wiring the Microlink API by hand means reading its x-api-key header scheme and building each URL-extraction, screenshot, or PDF query against the single endpoint yourself. Through Jentic you install once, import the Microlink API from the API Directory, store the API key once, and your agent calls it.

Permission scoping

Microlink exposes a single GET endpoint that takes the target URL as a parameter, so limit the agent to that extraction operation. You choose whether the agent may call it, and it reads a URL rather than changing data on your account.

Credential isolation

Your Microlink x-api-key is stored once, encrypted, by your own Jentic One instance and injected into the x-api-key header 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 title and image for a URL' or 'take a screenshot of a page', 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 Microlink API through Jentic.

What authentication does the Microlink API use?

Microlink uses an API key passed in the x-api-key header. There is also a free tier without a key, with stricter limits. Through Jentic the API key lives in the encrypted vault and is added to requests at execution time.

Can I take a screenshot of a page that requires login?

Microlink's browser automation parameters allow scripting clicks, form inputs, and waits before capture, which covers many login flows. For sensitive credentials, supply them through Microlink's secret parameters rather than embedding them in the URL.

What are the rate limits for the Microlink API?

Free, key-less requests are limited to a small per-minute and per-day quota; paid tiers raise the cap and allow higher concurrency. Inspect the X-RateLimit headers and Microlink's pricing page for the current per-tier numbers before scaling out a bulk job.

How do I extract metadata for a URL through Jentic?

Search Jentic for 'extract metadata from a URL', load GET /, and execute with the url query parameter. Jentic injects the x-api-key header from your stored Microlink credential.

Is the Microlink API free?

There is a free tier with limited rate and no SLA. Production use cases and higher quotas require a paid plan; check Microlink's pricing page for current tiers.

Does Microlink follow redirects and resolve canonical URLs?

Yes - Microlink follows redirects and exposes the resolved URL in its response, so link preview cards point to the canonical destination rather than the originally posted URL.

Can I limit what my agent is allowed to do with the Microlink API?

Yes. Because you run Jentic One yourself, your own rules decide which Microlink operations and credentials your agent may use. Microlink exposes a single GET endpoint that takes a target URL as a parameter, so you can permit your agent to call only that extraction operation, which reads a URL to return metadata, a screenshot, or a PDF rather than changing anything on your account. Your Microlink x-api-key stays with your self-hosted instance and is added to the request at execution time, so the agent never sees the key.

For Agents

Send any URL to Microlink and get back structured page metadata plus optional screenshots, PDFs, or scripted browser output for that URL.

Use for: I need to fetch the Open Graph metadata for a list of URLs, Generate a screenshot of a landing page, Render a web page as a PDF for archive, Extract the title and author from a news article URL

Not supported: Does not run a search engine, crawl entire sites, or store long-term archives - use for single-URL metadata extraction, screenshots, PDFs, and scripted browser actions only.

Microlink is a metadata extraction and browser automation API that turns any URL into structured data, screenshots, PDFs, and scripted browser actions with a single GET request. The single-endpoint API returns Open Graph and oEmbed-style attributes - title, description, author, image, logo, and publisher - alongside optional rendered artefacts. Authentication uses an API key passed in the x-api-key header.
