Brand Dev Ruby API library

The Brand Dev Ruby library provides convenient access to the Brand Dev REST API from any Ruby 3.2.0+ application. It ships with comprehensive types & docstrings in Yard, RBS, and RBI – see below for usage with Sorbet. The standard library's net/http is used as the HTTP transport, with connection pooling via the connection_pool gem.

It is generated with Stainless.

MCP Server

Use the Brand Dev MCP Server to enable AI assistants to interact with this API, allowing them to explore endpoints, make test requests, and use documentation to help integrate this SDK into your application.

Note: You may need to set environment variables in your MCP client.

Documentation

Documentation for releases of this gem can be found on RubyDoc.

The REST API documentation can be found on docs.context.dev.

Installation

To use this gem, install via Bundler by adding the following to your application's Gemfile:

gem"brand.dev","~> 1.2.0"

Usage

require"bundler/setup"require"brand_dev"brand_dev=BrandDev::Client.new(api_key: ENV["BRAND_DEV_API_KEY"]# This is the default and can be omitted)brand=brand_dev.brand.retrieve(domain: "REPLACE_ME")puts(brand.brand)

Handling 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 BrandDev::Errors::APIError will be thrown:

beginbrand=brand_dev.brand.retrieve(domain: "REPLACE_ME")rescueBrandDev::Errors::APIConnectionError=>eputs("The server could not be reached")puts(e.cause)# an underlying Exception, likely raised within `net/http`rescueBrandDev::Errors::RateLimitError=>eputs("A 429 status code was received; we should back off a bit.")rescueBrandDev::Errors::APIStatusError=>eputs("Another non-200-range status code was received")puts(e.status)end

Error codes are as follows:

Cause	Error Type
HTTP 400	BadRequestError
HTTP 401	AuthenticationError
HTTP 403	PermissionDeniedError
HTTP 404	NotFoundError
HTTP 409	ConflictError
HTTP 422	UnprocessableEntityError
HTTP 429	RateLimitError
HTTP >= 500	InternalServerError
Other HTTP error	APIStatusError
Timeout	APITimeoutError
Network error	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, >=500 Internal errors, and timeouts will all be retried by default.

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

# Configure the default for all requests:brand_dev=BrandDev::Client.new(max_retries: 0# default is 2)# Or, configure per-request:brand_dev.brand.retrieve(domain: "REPLACE_ME",request_options: {max_retries: 5})

Timeouts

By default, requests will time out after 60 seconds. You can use the timeout option to configure or disable this:

# Configure the default for all requests:brand_dev=BrandDev::Client.new(timeout: nil# default is 60)# Or, configure per-request:brand_dev.brand.retrieve(domain: "REPLACE_ME",request_options: {timeout: 5})

On timeout, BrandDev::Errors::APITimeoutError is raised.

Note that requests that time out are retried by default.

Advanced concepts

BaseModel

All parameter and response objects inherit from BrandDev::Internal::Type::BaseModel, which provides several conveniences, including:

1. All fields, including unknown ones, are accessible with obj[:prop] syntax, and can be destructured with obj => {prop: prop} or pattern-matching syntax.

2. Structural equivalence for equality; if two API calls return the same values, comparing the responses with == will return true.

3. Both instances and the classes themselves can be pretty-printed.

4. Helpers such as #to_h, #deep_to_h, #to_json, and #to_yaml.

Making custom or undocumented requests

Undocumented properties

You can send undocumented parameters to any endpoint, and read undocumented response properties, like so:

Note: the extra_ parameters of the same name overrides the documented parameters.

brand=brand_dev.brand.retrieve(domain: "REPLACE_ME",request_options: {extra_query: {my_query_parameter: value},extra_body: {my_body_parameter: value},extra_headers: {"my-header": value}})puts(brand[:my_undocumented_property])

Undocumented request params

If you want to explicitly send an extra param, you can do so with the extra_query, extra_body, and extra_headers under the request_options: parameter when making a request, as seen in the examples above.

Undocumented endpoints

To make requests to undocumented endpoints while retaining the benefit of auth, retries, and so on, you can make requests using client.request, like so:

response=client.request(method: :post,path: '/undocumented/endpoint',query: {"dog": "woof"},headers: {"useful-header": "interesting-value"},body: {"hello": "world"})

Concurrency & connection pooling

The BrandDev::Client instances are threadsafe, but are only are fork-safe when there are no in-flight HTTP requests.

Each instance of BrandDev::Client has its own HTTP connection pool with a default size of 99. As such, we recommend instantiating the client once per application in most settings.

When all available connections from the pool are checked out, requests wait for a new connection to become available, with queue time counting towards the request timeout.

Unless otherwise specified, other classes in the SDK do not have locks protecting their underlying data structure.

Sorbet

This library provides comprehensive RBI definitions, and has no dependency on sorbet-runtime.

You can provide typesafe request parameters like so:

brand_dev.brand.retrieve(domain: "REPLACE_ME")

Or, equivalently:

# Hashes work, but are not typesafe:brand_dev.brand.retrieve(domain: "REPLACE_ME")# You can also splat a full Params class:params=BrandDev::BrandRetrieveParams.new(domain: "REPLACE_ME")brand_dev.brand.retrieve(**params)

Enums

Since this library does not depend on sorbet-runtime, it cannot provide T::Enum instances. Instead, we provide "tagged symbols" instead, which is always a primitive at runtime:

# :albanianputs(BrandDev::BrandRetrieveParams::ForceLanguage::ALBANIAN)# Revealed type: `T.all(BrandDev::BrandRetrieveParams::ForceLanguage, Symbol)`T.reveal_type(BrandDev::BrandRetrieveParams::ForceLanguage::ALBANIAN)

Enum parameters have a "relaxed" type, so you can either pass in enum constants or their literal value:

# Using the enum constants preserves the tagged type information:brand_dev.brand.retrieve(force_language: BrandDev::BrandRetrieveParams::ForceLanguage::ALBANIAN,# …)# Literal values are also permissible:brand_dev.brand.retrieve(force_language: :albanian,# …)

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.

This package considers improvements to the (non-runtime) *.rbi and *.rbs type definitions to be non-breaking changes.

Requirements

Ruby 3.2.0 or higher.
