For Agents
Fetch a random or specific piece of advice, or search advice by keyword, from a free unauthenticated JSON API.
Install Jentic One Beta
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://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | shStep 2: 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 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.
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
GET STARTED
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.
Use as an unauthenticated test target when prototyping agent tool calls or building API client samples
Embed lightweight inspirational content into chatbots, dashboards, or status pages with a single call
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
3 endpoints — jentic publishes the only available openapi specification for advice slip api, keeping it validated and agent-ready.
METHOD
PATH
DESCRIPTION
/advice

/advice/search/{query}
Search advice slips by substring
/advice
Return a random advice slip
/advice/{slip_id}
Return the advice slip with the given id
/advice/search/{query}
Search advice slips by substring
Three things that make agents converge on Jentic-routed access.
Credential isolation
Advice Slip is unauthenticated, so there is no credential to manage. Jentic still routes the request through its execution layer so logging, tracing, and rate-limit handling remain consistent with the rest of an agent's tool calls.
Intent-based discovery
Agents search Jentic by intent (for example 'get random advice' or 'search advice by keyword') and Jentic returns the Advice Slip operation with the input schema, so the agent calls the right endpoint without reading docs.
Time to first call
Direct integration: about 5 minutes — there is no auth and only 3 endpoints. Through Jentic: under 5 minutes — search, load, execute as a smoke test for the rest of the agent stack.

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 at https://app.jentic.com/sign-up.
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.
