Power your generative and agentic applications with Coveo's intelligent Passage Retrieval API. An AWS-ready, developer-first solution for grounding AI assistants with enterprise-verified knowledge. Built to integrate with Amazon Bedrock and Q Business, Passage Retrieval is your composable retrieval layer for high-performance, secure, and scalable LLM experiences.
Overview
Built for developers, Coveo's Passage Retrieval API delivers real-time, enterprise-grade grounded retrieval for generative and agentic applications. Acting as the intelligent retrieval layer in your stack, Passage Retrieval API seamlessly integrates with Amazon Bedrock action groups, Amazon Q Business plugins and others alike, to retrieve contextually relevant, enterprise-verified knowledge from across your unified index. With no need to duplicate or migrate data, Coveo connects to your existing repositories via native and universal connectors.
Coveo's Passage Retrieval API retrieves structured and unstructured enterprise data, enforcing permission models, while delivering relevance at scale. Developers can embed Passage Retrieval API directly into their LLM workflows to improve response quality, accelerate time to value, and ensure AI outputs are based on secure, verified knowledge. In addition, Coveo's robust analytic tools track retrieval usage and performance to monitor AI grounding quality, detect content gaps, and continuously improve your generative experiences. Every query feeds Coveo's analytics engine. This powers relevance tuning, identifies content gaps, and uncovers optimization opportunities in a centralized Knowledge Hub.
Whether you're powering an AI agent, co-pilot, or advanced GenAI product on AWS, Coveo APIs enhance every answer with accuracy, transparency, and speed.
Coveo's API Suite is built for developers designing custom generative or agentic experiences on AWS, with Search, Retrieval and Answer APIs. Use them directly in Amazon Bedrock, Amazon Q Business, or your own custom stack via an MCP Server.
Fully managed or composable, Coveo's platform is built to adapt to your needs.

Dimensions summary
This listing uses a contract pricing model with one usage dimension: Passage Retrieval calls. You are billed per call made to the Passage Retrieval API. Each call retrieves relevant text passages from your unified content index to feed your large language model. Because pricing tracks a single unit, your cost scales directly with the number of API calls your applications make. There are no separate tiers or instance sizes to choose between. As your generative AI usage grows across more applications or users, your billed call volume rises accordingly under the same per-call rate.
Top-of-mind questions for buyers
One call is a single request your application sends to the Passage Retrieval API. That request retrieves relevant text chunks from your unified index, along with source links and relevance scores. Each query your generative AI app triggers counts as one billable call, regardless of how many passages come back.
You can reuse a single unified index and existing query pipelines across many applications. Adding more apps, chatbots, or users increases the number of API calls made. Your billed volume rises with total calls across all applications, since every retrieval request counts under the same per-call unit.
The listing meters only Passage Retrieval calls. The product connects to content sources and builds a unified index to feed your language model. The pricing table shows no separate dimension for indexing or connectors. For details on infrastructure or indexing costs beyond calls, contact the vendor.

Usage instructions
API
To use the Coveo Passage Retrieval API (PR API) you will need the following items:
- Your Organization ID (e.g., mycompanyxyz123).
- An API key to authorize requests.
Follow these steps to configure Coveo in order to access your PR API endpoint and perform a test call.
1) Index your data
This step assumes that you're starting from an empty Coveo organization. Skip it if you already have content indexed in Coveo .
2) Configure the PR API
In the Coveo Platform Admin :
- Create a Passage Retrieval (CPR) model and associate it to a query pipeline.
- Ensure that the same pipeline is also associated with a Semantic Encoder (SE) model.
For complete step-by-step setup details, see: https://docs.coveo.com/en/o86c8334/build-a-search-ui/use-the-passage-retrieval-api
3) Create an API key
Create an API key and use it as a Bearer token in the Authorization header in the test call (step 4).
4) Make a test call (cURL)
In the following curl request, replace ORG_ID and API_KEY with your values.
curl -X POST <https://ORG_ID.org.coveo.com/rest/search/v3/passages/retrieve> -H "Authorization: Bearer API_KEY" -H "Content-Type: application/json" -d '{ "query": "", "additionalFields": ["clickableuri"], "maxPassages": 5, "localization": { "locale": "en-CA", "timezone": "America/Montreal" } }'
Expected response contains an items array with ranked passages and a responseId.
Please refer to Coveo's PR API documentation for more details on how to use Coveo's PR API.
