go-vectara

Unofficial Go client for the Vectara API v2. Package vectara (github.com/psyb0t/go-vectara) has typed methods for corpora, documents, search, RAG queries, chats, agents, tools, pipelines and account administration. Use when Go code needs Vectara or already imports go-vectara.

Unofficial, typed Go client for the Vectara API v2, in package vectara at the module root.

For installation, operations, pagination and response fields, see references/setup.md.

Security & safety

• Read an API key from VECTARA_API_KEY and send it in x-api-key. Never hardcode, commit or log credentials or authentication headers.
• Use https://api.vectara.io as the base URL. Generated paths include /v2.
• OAuth uses a bearer access token. Visitor tokens and federated bearer credentials work only on operations declaring those schemes.
• Creating, updating, deleting or resetting resources changes account data. Run those operations only when the user requests them. Queries and agent execution may consume account resources or invoke configured tools.

When to use

• Go code needs Vectara corpora, documents, retrieval or RAG queries.
• Go code needs Vectara chats, agents, tools or pipelines.
• The project imports github.com/psyb0t/go-vectara.

When not to use

• The code is not Go. This module ships only a Go package.
• You need a client maintained by Vectara. This client is unofficial.
• You want to change the generated client. See AGENTS.md in the repo.

Finding endpoints and types

The usage below covers one call. Every operation in the spec has a generated method, and the spec's descriptions are on them as Go doc comments. Look names and fields up instead of guessing. After go get github.com/psyb0t/go-vectara, from inside your module:

bash

go doc github.com/psyb0t/go-vectara ClientWithResponsesInterface  # every endpoint method
go doc github.com/psyb0t/go-vectara ListCorporaParams              # one method, params type or model
go doc -all github.com/psyb0t/go-vectara                           # the whole package

The same documentation is at https://pkg.go.dev/github.com/psyb0t/go-vectara.

Method names come from the spec's operation IDs. <OperationId>WithResponse takes the context, then the path parameters in order, then *<OperationId>Params when the operation has query or header parameters, then the request body when it has one. Almost every operation takes a params struct, because the spec declares request timeout headers on them; pass nil when you set none. The JSON200 field (or JSON201 and so on, per declared status) holds the decoded body; it is nil for any other status.

Usage

Set x-api-key with a request editor, create the client, then call an operation. This is the repo's example_test.go:

go

import (
	"context"
	"net/http"
	"os"

	"github.com/psyb0t/go-vectara"
)

auth := vectara.WithRequestEditorFn(func(_ context.Context, req *http.Request) error {
	req.Header.Set("x-api-key", os.Getenv("VECTARA_API_KEY"))

	return nil
})

client, err := vectara.NewClientWithResponses("https://api.vectara.io", auth)
if err != nil {
	return err
}

res, err := client.ListCorporaWithResponse(context.Background(), nil)
if err != nil {
	return err
}

_ = res.JSON200 // *vectara.ListCorporaResponse

Check err for request construction, transport and decoding failures. Check StatusCode() and the expected success field such as JSON200 for API failures. A non-2xx response can have a nil Go error. Optional fields may be pointers; check before dereferencing.

The client does not paginate, retry or refresh OAuth tokens automatically. For server-sent events, call the raw method, decode the stream yourself and close the response body. Parsed response methods read the full body.
