Install Jentic One Beta

Connect the Advice Slip API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Advice Slip 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%2Fadviceslip.com%2Fadviceslip" | 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%2Fadviceslip.com%2Fadviceslip" | 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 Advice Slip API.

Pull a random advice slip via GET /advice for placeholder content in demos and onboarding flows

Retrieve a specific advice slip by its numeric id via GET /advice/{slip_id} for stable, citable quotes

Search the advice corpus by substring via GET /advice/search/{query} to surface matching slips

Use as an unauthenticated test target when prototyping agent tool calls or building API client samples

Use Cases

Patterns agents use Advice Slip API for, with concrete tasks.

★ Random Content for Demos and Tutorials

When teaching API integration, building a prototype, or filling a UI with placeholder text, the Advice Slip random endpoint returns a short JSON payload with no authentication. Tutorials use it to demonstrate fetch and parse loops, and prototype dashboards use it to fill empty states. The whole integration is a single GET /advice call returning a small slip object.

Call GET /advice and return the returned slip's advice field as a string

Searchable Advice Corpus

Build features that surface relevant advice based on a user keyword. The /advice/search/{query} endpoint accepts a substring and returns all matching slips. This is useful for chat experiences where a user types a topic ('focus', 'money') and the agent returns related slips, or for content tools that pull a quote matching an article's theme.

Call GET /advice/search/money and return the first three slips whose advice text contains the word 'money'

Stable Daily Quote by ID

Use a numeric slip id when the application needs a deterministic piece of content - a daily inspiration card, a saved favourite, or a citation. /advice/{slip_id} returns the same slip every call for a given id, so a 'quote of the day' rotation can pin specific ids per date without storing the text locally.

Call GET /advice/117 and return that slip's advice text for a 'quote of the day' display

Agent Smoke Test via Jentic

When validating a new Jentic agent setup or MCP wiring, the Advice Slip API is the lowest-friction call available - no key, no rate-limit setup, no payload to construct. An agent can search Jentic for 'random advice', load the operation, and execute it as a smoke test that confirms the search-load-execute path works before wiring up a credentialed API.

Use Jentic to search 'get random advice', load the GET /advice operation, and execute it to confirm the agent's tool-call path returns a valid slip

Why Jentic?

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

Setup

The Advice Slip API is unauthenticated, so wiring it by hand still leaves you writing your own request, retry, and rate-limit handling. Through Jentic you install once, import Advice Slip from the API Directory, and your agent calls it through the same execution layer as your other tools.

Permission scoping

Advice Slip takes its slip id and search query in the URL path for read-only lookups, so you limit the agent to the operations it needs, such as getting random advice or searching by keyword. Every operation on this surface is read-only, so the agent reads advice without changing anything.

Credential isolation

Advice Slip is unauthenticated, so there is no credential to store. Jentic still routes the request through its execution layer so logging, tracing, and rate-limit handling stay consistent with the agent's other calls.

Intent-based discovery

Agents search Jentic by intent such as 'get random advice' or 'search advice by keyword', and Jentic returns the matching Advice Slip operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Advice Slip API through Jentic.

Why is there no official OpenAPI spec for Advice Slip API?

Advice Slip does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Advice Slip API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the Advice Slip API use?

None. The Advice Slip API is fully unauthenticated - there are no securitySchemes in the spec and no header or query credential is required. When called through Jentic the request is dispatched without a vault credential.

Can I search advice slips by keyword with the Advice Slip API?

Yes. GET /advice/search/{query} performs a substring match against the advice corpus and returns every slip whose text contains the query. The response includes the total match count and the matching slip objects.

How do I get a random piece of advice through Jentic?

Search Jentic for 'get random advice', load the GET /advice operation, and execute it. Because the API has no auth, the call returns a slip immediately and is a useful smoke test for new Jentic agent integrations.

Is the Advice Slip API free?

Yes. Advice Slip is a free public API with no authentication, no paid tier, and no published rate limit. Treat it as best-effort - do not build production-critical features on top of it without caching.

Can I retrieve a specific advice slip by id?

Yes. GET /advice/{slip_id} accepts a numeric id and returns the same slip on every call, which makes it suitable for stable references such as daily-quote rotations or saved favourites.

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

Yes. Because Jentic One is self-hosted, your own rules decide which Advice Slip operations the agent may call, so you can allow just getting random advice, looking up a slip by id, or searching by keyword and block the rest. Every operation on this API is read-only and takes its slip id or search query in the URL path, so the agent reads advice without changing any data. The API needs no credentials, so you scope access purely by the operations you expose to the agent.

For Agents

Fetch a random or specific piece of advice, or search advice by keyword, from a free unauthenticated JSON API.

Use for: Get a random piece of advice, Look up advice slip number 42, Search advice slips for the word patience, Find all advice containing the keyword money

Not supported: Does not handle authoring, user submissions, ratings, or attribution - use for read-only random-advice lookups only.

Jentic publishes the only available OpenAPI specification for Advice Slip API, keeping it validated and agent-ready. The Advice Slip API returns short pieces of advice as JSON, intended as a free, no-auth content source for demos, tutorials, and prototype apps. Three endpoints cover a random advice slip, lookup of a slip by numeric id, and a substring search across the advice corpus. Because no API key is required, it is one of the simplest endpoints to wire into an agent or a beginner tutorial.
