HTTParty
Simple HTTP client for Ruby with automatic JSON and XML parsing. HTTParty provides a declarative mixin for creating API client classes: include HTTParty; base_uri 'https://api.example.com'; headers 'Authorization' => 'Bearer token'. Provides .get, .post, .put, .patch, .delete class methods returning parsed response objects. Auto-parses JSON and XML responses. Supports: query parameters, request bodies, timeouts, basic auth, digest auth, SSL configuration, and response code checking. Popular for quick API integrations in Rails apps and scripts — simpler than Faraday but less configurable.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
SSL verification enabled by default. API keys in headers should come from environment variables, not hardcoded. HTTParty logs requests at debug level — ensure production agent API keys don't appear in log output. No request body encryption beyond HTTPS.
⚡ Reliability
Best When
You need a simple, readable Ruby HTTP client for agent API integrations with automatic JSON parsing — HTTParty is the 'parses-JSON-so-you-don't-have-to' library for straightforward agent HTTP calls.
Avoid When
You need middleware (retries, logging, metrics), connection pooling, async HTTP, or streaming responses — use Faraday or net-http for those cases.
Use Cases
- • Create typed agent API client class — class AgentAPIClient; include HTTParty; base_uri ENV['AGENT_API_URL']; headers 'Authorization' => bearer_token; def get_agents; self.class.get('/agents'); end
- • Call external tools from agent service — HTTParty.post(tool_url, body: {query: agent_query}.to_json, headers: {'Content-Type' => 'application/json'}) for one-off agent tool API calls
- • Parse agent API JSON responses automatically — HTTParty auto-parses JSON; response['agents'].each for direct hash access to agent API response without manual JSON.parse
- • Agent API integration in Rails scripts — HTTParty.get(webhook_url, query: {agent_id: id, status: 'complete'}) for simple agent status webhook callbacks
- • Handle agent API authentication — HTTParty.post(url, basic_auth: {username: key, password: secret}) for APIs requiring basic auth in agent service integrations
Not For
- • Complex HTTP requirements — HTTParty is simple; use Faraday for middleware pipeline (retry, logging, auth plugins), connection pooling, and custom adapters for production agent HTTP clients
- • Streaming HTTP responses — HTTParty doesn't support streaming; use Net::HTTP or Faraday with adapter for streaming agent LLM API responses
- • Async HTTP calls — HTTParty is synchronous blocking; use async-http or EventMachine for concurrent agent API calls
Interface
Authentication
Auth via headers option: headers 'Authorization' => 'Bearer token'. Built-in basic_auth: option. digest_auth: option for Digest authentication. No built-in OAuth flow.

Agent Metadata
Known Gotchas
- ⚠ Non-2xx responses don't raise by default — HTTParty returns response object even for 404, 429, 500; agent code must check response.code or response.success?; forgetting status check causes agent to process error JSON as success response
- ⚠ No built-in retry logic — HTTParty has no retry mechanism; agent code that calls external APIs must implement retry with backoff manually or wrap HTTParty in a retry gem (retryable, retriable) for transient agent API failures
- ⚠ SSL verification on by default — HTTParty verifies SSL certificates; self-signed certificates in dev environments cause OpenSSL::SSL::SSLError; disable with verify: false for development only, never production agent deployments
- ⚠ Base URI and per-call URI concatenation — base_uri 'https://api.example.com/v1' with get('/agents') produces 'https://api.example.com/v1/agents'; leading slash matters; get('agents') without slash concatenates incorrectly producing malformed agent API URLs
- ⚠ Response parsing depends on Content-Type — HTTParty auto-parses only if server returns correct Content-Type (application/json, text/xml); if agent API returns JSON with wrong content type, response is raw string not hash; use response.parsed_response carefully
- ⚠ Class-level configuration is global — HTTParty class methods (base_uri, headers, default_params) set on class are global for all instances; agent API client subclasses share parent class config unless overridden; use separate classes for different agent API environments
