Which Retrieval API do you need?
The question you arrived with, and the API that answers it.
What is the Retrieval Kit?
The Retrieval Kit is the layer that decides what your model sees. It compares, ranks and tags content so the most relevant information reaches the prompt.
It powers the features users notice most: search that understands intent, answers grounded in your own data, and routing that sends each request to the right place.
How AI products use it
- Rank the most relevant documents before your model writes an answer.
- Tag incoming tickets by keyword and language to route them.
- Find similar records to suggest matches or remove duplicates.
Why not build it in-house?
Each capability in the Retrieval Kit looks simple to build. The hard part is keeping it accurate, available and up to date once your product depends on it.
- Similarity and rankingGood ranking needs embedding models, scoring logic and evaluation sets. Changing any of them can silently make answers worse.
- Keyword extractionExtraction has to handle domain jargon, multiple languages and noisy text, and it needs tuning every time your content changes.
- Language detectionShort texts, mixed languages and similar languages trip up detectors. Wrong detection sends content to the wrong model or team.
- Running it at scaleRetrieval runs on every query. Latency and compute costs grow with your users, so it needs capacity planning and monitoring.
Do you run an API that belongs in the Retrieval Kit?
Publish it on ApyHub and put it in front of the teams and AI agents building with the Retrieval Kit. Your API joins the catalog under one subscription, becomes callable through MCP, and earns from every call.
Questions about the Retrieval Kit
What is the ApyHub Retrieval Kit?
The Retrieval Kit is the layer that decides what your model sees. It compares, ranks and tags content so the most relevant information reaches the prompt.
What is a semantic search API?
A semantic search API finds content by meaning rather than exact words. It compares a query with your documents and ranks them by how closely they match.
How do I rank documents for RAG?
Send the user's question and your candidate passages to Compare and Rank Text Similarity. It returns each candidate with a similarity score, so you pass only the most relevant passages to your model.
What is a keyword extraction API used for?
Keyword extraction pulls the main terms out of a text. AI products use it to tag content, route support tickets, build search filters and summarize what a document is about.
Can the Retrieval Kit detect the language of a text?
Yes. Language Detection and AI Text Language Detection identify the language of a text, so you can route multilingual content to the right model or team.
Can I test Retrieval Kit APIs before integrating them?
Yes. Every API has a Try it panel on its service page. Your key is filled in, you send a real request and see the actual response in your browser before you write any code.
Can AI agents use the Retrieval Kit?
Yes. Every endpoint is MCP-ready. Connect ApyHub MCP to Claude, ChatGPT, Cursor, Mistral Le Chat or any MCP-compatible agent, and your agent can discover and call these APIs directly.
How is it priced?
Every kit sits under one subscription, paid in atoms, ApyHub's usage unit. Every call shows its cost, and the free Starter plan needs no card.
