Install Jentic One Beta

Connect the SimpMusic Lyrics API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the SimpMusic Lyrics 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%2Flyrics.simpmusic.org%2Flyrics-simpmusic" | 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%2Flyrics.simpmusic.org%2Flyrics-simpmusic" | 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 SimpMusic Lyrics API for, with concrete tasks.

★ Serve lyrics to an AI agent

An AI agent integration created through Jentic needs the words to a track. The SimpMusic Lyrics API returns synced or plain lyrics for a video id and supports search by title or artist, so the agent can fetch and display lyrics inside a music or chat experience without maintaining its own lyrics store.

Search lyrics by song title, then fetch the synced lyrics for the matching video id

Show translated lyrics

Listeners often want lyrics in another language. The SimpMusic Lyrics API fetches community translations for a video id and a specific language, so an automation can present a translated version alongside the original and fall back to the plain lyrics when no translation exists.

Fetch the translated lyrics for a video id in a chosen language

Crowdsource lyric contributions

Missing or wrong lyrics improve through contributions. The SimpMusic Lyrics API lets a caller submit a new lyric or translation and vote on accuracy, so an agent can add lyrics it has verified and raise the ranking of correct entries, with contribution calls signed by an HMAC header.

Submit a new lyric for a video id and vote on an existing translation

Why Jentic?

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

Setup

Wiring the SimpMusic Lyrics API by hand means signing contribution requests with an HMAC header while leaving read and search calls unauthenticated. Through Jentic you install once, import SimpMusic Lyrics from the API Directory, store the signing key once, and your agent calls it.

Permission scoping

The video id sits in the URL path for reads, so a rule can keep your agent read-only by allowing only the lookup and search operations. You choose the operations it may call, so contribution operations like creating lyrics or voting are not included unless you add them.

Credential isolation

Your SimpMusic signing key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'get lyrics by video id' or 'search lyrics by artist', and Jentic returns the matching SimpMusic Lyrics operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using SimpMusic Lyrics API through Jentic.

What authentication does the SimpMusic Lyrics API use?

The read and search endpoints of the SimpMusic Lyrics API are public and need no credential, while the contribution endpoints that create lyrics, add translations, or vote require an HMAC signature in the X-HMAC header, per its OpenAPI spec. Through Jentic the signing key is stored encrypted by your own Jentic One instance and injected at call time.

Can I search for lyrics with the SimpMusic Lyrics API?

Yes. The search endpoint accepts free text, and dedicated endpoints search by song title or artist, so an agent can find a track and then fetch its synced or plain lyrics by video id.

What are the rate limits for the SimpMusic Lyrics API?

The SimpMusic Lyrics API spec documents a limit of 30 requests per minute per IP address, applied across all endpoints, with rate-limit headers returned on responses. Design agent flows to stay within that ceiling and back off when it is reached.

How do I fetch song lyrics through Jentic?

Install Jentic One on your own infrastructure with `curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh`, then import the SimpMusic Lyrics API from the API Directory and search for 'get song lyrics by video id'. Reads need no credential, and storing the HMAC key once lets your agent contribute too. To run it on your own infrastructure, install Jentic One from its GitHub repo.

Is there a SimpMusic Lyrics MCP server?

You don't need an MCP server to give your agent the SimpMusic Lyrics API. Jentic connects it directly from the API Directory: import it, and your agent calls the public read endpoints or signs contributions, with operations discovered on demand instead of loaded into the agent's context.

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

Yes. The video id sits in the URL path for reads, so a rule can allow only the lookup and search operations, keeping the agent read-only while contribution operations like creating lyrics or voting stay out of reach unless you add them. Every action it takes is recorded in an audit log.
