For Agents
Programmatically create a corpus, list corpora. Covers 12 operations with bearer authentication.
Use for: I need to a corpus, I want to corpora, Search for a corpus, Find all a corpus
Not supported: Does not handle payments, communications, or crm - use for developer tools only.
Vectara is a GenAI platform providing Retrieval Augmented Generation (RAG) as a service. The API enables corpus management, document indexing, and semantic search with grounded generation. The API exposes 12 endpoints secured with bearer authentication.
Install Jentic One Beta
Connect the Vectara API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Vectara 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%2Fvectara.com%2Fvectara" | sh2
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%2Fvectara.com%2Fvectara" | 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.
Capabilities
What an agent can do with Vectara API.
Create a corpus
List corpora
Get a corpus
Update a corpus
Delete a corpus
Add a document to a corpus
Use Cases
Patterns agents use Vectara API for, with concrete tasks.
★ Developer Tools Operations
Use the Vectara API to perform developer tools operations programmatically. The API provides 12 endpoints covering core functionality including create a corpus, list corpora, get a corpus.
Call POST /corpora to create a corpus
Automated Chat Management
Automate chat operations by combining multiple Vectara API endpoints. Agents can list corpora and then get a corpus in a single workflow.
Call GET /corpora to list corpora, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Vectara API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle bearer tokens manually.
Search Jentic for 'create a corpus', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Vectara API by hand means handling its bearer JWT auth against api.vectara.io and coding each corpus and document operation yourself. Through Jentic you install once, import the Vectara API from the API Directory, store the token once, and your agent calls it.
Permission scoping
Vectara puts the corpus key and document id in the URL path (/corpora/{corpus_key}, /corpora/{corpus_key}/documents/{document_id}), so a rule can pin your agent to one corpus. You choose the operations it may call, so destructive ones like deleting a corpus or a document are not included unless you add them.
Credential isolation
Your Vectara bearer token 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 'create a corpus' or 'add a document to a corpus', and Jentic returns the matching Vectara operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Vectara API through Jentic.
What authentication does the Vectara API use?
The Vectara API uses a Bearer token in the Authorization header. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I create a corpus with the Vectara API?
Yes. Use the POST /corpora endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Vectara API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I create a corpus through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create a corpus'. Jentic returns the matching Vectara API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Vectara API have?
The Vectara API exposes 12 endpoints covering chat, chats, corpora operations.
Can I limit what my agent is allowed to do with the Vectara API?
Yes. Because you run Jentic One yourself, your own rules decide which Vectara operations and credentials the agent may use. Vectara puts the corpus key and document id in the URL path (/corpora/{corpus_key} and /corpora/{corpus_key}/documents/{document_id}), so you can pin the agent to a single corpus and grant only read operations like listing corpora and getting documents. Destructive calls such as deleting a corpus or a document stay off unless you explicitly add them.
