Zazu Ruby SDK

Ruby SDK for the Zazu API. Faraday + HTTPX adapter for HTTP/2 + persistent connections.

gem "zazu-ruby"

The gem is published as zazu-ruby on RubyGems but loaded as zazu in code (the zazu name was already taken by an unrelated 2014-era gem).

Quick start

require "zazu"

zazu = Zazu.new(api_key: ENV["ZAZU_API_KEY"])
# Or with explicit base URL (defaults to https://zazu.ma):
zazu = Zazu.new(api_key: ENV["ZAZU_API_KEY"], base_url: "https://zazu.africa")

entity = zazu.entity.get
# => #<Zazu::Response status=200 ...>
entity.body["name"]
# => "Acme Corp"

Environment variables ZAZU_API_KEY, ZAZU_BASE_URL, ZAZU_API_VERSION, and ZAZU_TIMEOUT are read by default.

Pagination

Every list endpoint returns a Zazu::Page. The SDK enforces a hard cap of 100 records per page — there is no auto-pagination across pages.

page = zazu.invoices.list(limit: 100)
page.data         # => Array of invoice hashes
page.has_more     # => true / false
page.next_cursor  # => string or nil

# Walk pages explicitly:
while page
  page.data.each { |inv| process(inv) }
  page = page.next  # returns nil when has_more is false
end

For capped iteration, use the underlying each_page_record helper on a resource (private; access via send if you need it). The deliberate restriction is a guardrail — accidentally pulling 50,000 records in a single SDK call should be impossible without explicit per-page consent.

Errors

Every non-2xx response raises a subclass of Zazu::Error:

Status	Class
401	Zazu::AuthenticationError
403	Zazu::ForbiddenError
404	Zazu::NotFoundError
422	Zazu::ValidationError
429	Zazu::RateLimitError (carries #retry_after)
5xx	Zazu::ServerError
network	Zazu::ConnectionError

Each error exposes #status, #request_id, #type, #param, and the raw #body.

begin
  zazu.invoices.get("does-not-exist")
rescue Zazu::NotFoundError => e
  e.status      # => 404
  e.request_id  # => "req_..."
  e.type        # => "not_found_error"
end

Versioning the API contract

zazu = Zazu.new(api_key: "...", api_version: "2026-03-27")

Or via env: ZAZU_API_VERSION=2026-03-27. The header is sent on every request; the API echoes it back in Zazu-Version.

Development

bundle install
bundle exec rspec
bundle exec rubocop

The spec suite is VCR-backed — cassettes live in spec/fixtures/cassettes/ and are committed to the repo.

To re-record cassettes against staging:

cp .env.example .env
# fill in ZAZU_STAGING_API_KEY and the ZAZU_FIXTURE_*_ID values
bundle exec rake fixtures:record

Cassettes are scrubbed before write — bearer tokens and request IDs are rewritten to placeholders. Even if a real key is in .env, the committed cassette never contains it.

Cassettes for other-language SDKs

Each release of zazu-ruby publishes the cassette directory as a tarball release asset:

https://github.com/getzazu/zazu-ruby/releases/download/v0.1.0/cassettes-v0.1.0.tar.gz

zazu-go, zazu-python, etc. pin a specific version in their .zazu-fixtures file and download the tarball during CI. This guarantees every SDK is tested against the same recorded API interactions, surfacing cross-SDK inconsistencies immediately.

VCR's YAML format is supported natively by:

• Ruby — VCR (this gem)
• Go — go-vcr
• Python — VCR.py
• PHP — PHP-VCR
• Crystal — vcr-crystal / hi8.cr
• Rust — http_replayer (or a small custom YAML reader)
• JavaScript / TypeScript — Talkback or polly.js (slight format adapter needed)
