Installation

To use this gem during the beta, install directly from GitHub with Bundler by adding the following to your application's Gemfile:

gem "braintrust", git: "https://github.com/braintrustdata/braintrust-ruby", branch: "main"

To fetch an initial copy of the gem:

bundle install

To update the version used by your application when updates are pushed to GitHub:

bundle update braintrust

Usage

require "braintrust"

braintrust = Braintrust::Client.new(
  api_key: "My API Key" # defaults to ENV["BRAINTRUST_API_KEY"]
)

project = braintrust.projects.create(name: "foobar")

puts project.id

Errors

When the library is unable to connect to the API, or if the API returns a non-success status code (i.e., 4xx or 5xx response), a subclass of Braintrust::HTTP::Error will be thrown:

begin
  project = braintrust.projects.create(name: "foobar")
rescue Braintrust::HTTP::Error => e
  puts e.code # 400
end

Error codes are as followed:

Status Code	Error Type
400	BadRequestError
401	AuthenticationError
403	PermissionDeniedError
404	NotFoundError
409	ConflictError
422	UnprocessableEntityError
429	RateLimitError
>=500	InternalServerError
(else)	APIStatusError
N/A	APIConnectionError

Retries

Certain errors will be automatically retried 2 times by default, with a short exponential backoff. Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict, 429 Rate Limit, and >=500 Internal errors will all be retried by default.

You can use the max_retries option to configure or disable this:

# Configure the default for all requests:
braintrust = Braintrust::Client.new(
  max_retries: 0 # default is 2
)

# Or, configure per-request:
braintrust.projects.create(name: "foobar", max_retries: 5)

Versioning

This package follows SemVer conventions. As the library is in initial development and has a major version of 0, APIs may change at any time.

Requirements

Ruby 3.0 or higher.
