For Agents

Exercise and verify HTTP client behaviour against 73 well-known test endpoints covering methods, status codes, auth, cookies, redirects, and encodings.

Quickstart

Get started with httpbin.org in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"echo an http request for testing"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Capabilities

What an agent can do with httpbin.org API.

Echo back request method, headers, query string, and body via /get, /post, /put, /patch, /delete, and /anything

Return any HTTP status code on demand to test client error handling and retries

Exercise basic, bearer, digest, and hidden basic-auth flows for client credential testing

Set, read, and delete cookies through the /cookies family of endpoints

Use for: I need to test how my HTTP client handles a 500 error, Verify that my agent retries on a 429 response, Echo a POST request body back to confirm headers were sent correctly, Check whether my client decompresses gzip responses

Not supported: Does not host real applications, persist data between requests, or handle production traffic — use for HTTP client and middleware testing only.

httpbin.org is a free, public HTTP request and response service used to test, debug, and demonstrate HTTP clients, proxies, and middleware. Endpoints echo request data, simulate status codes, exercise common authentication schemes, set and read cookies, return delays and streaming responses, and serve common encodings such as gzip, deflate, brotli, and base64. It is the standard reference target for verifying HTTP behaviour in CI pipelines, agent tool tests, and SDK integration suites.

Use Cases

Patterns agents use httpbin.org API for, with concrete tasks.

★ HTTP Client Conformance Testing

Verify that an HTTP client library or SDK correctly handles methods, headers, query parameters, status codes, and bodies by directing tests at httpbin endpoints. /anything echoes the full request shape, while /status/{codes} returns arbitrary status codes for error-path coverage. The service is free, public, and stable enough for CI use.

Send a POST to /anything with a JSON body and assert the response echoes the same headers and body fields.

Retry and Timeout Logic Validation

Validate retry policies and timeout behaviour by hitting /status/{codes} with codes like 500, 502, and 429, or /delay/{delay} to simulate slow responses. This produces deterministic, reproducible failure modes so retry middleware can be tuned with confidence.

GET /delay/5 with a 2-second client timeout and confirm the client raises a timeout error.

Authentication Scheme Demos

Demonstrate and test how a client handles HTTP basic, bearer, and digest authentication. /basic-auth/{user}/{passwd} and /bearer return 401 unless valid credentials are supplied, making them ideal targets for credential-handling tests in agent frameworks.

GET /basic-auth/user/pass with the matching credentials and confirm a 200 response with the authenticated payload.

Agent Tool Smoke Tests via Jentic

When validating that a Jentic-mediated tool call actually reaches the target server, point the agent at httpbin and inspect the echoed request. This isolates network and tool-execution issues from real-API behaviour during agent development.

Search Jentic for echo an http request, load /anything on httpbin, and execute with custom headers to confirm the agent sent them correctly.

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

httpbin.org is unauthenticated, so Jentic does not need to inject credentials. This makes it the cleanest possible target for verifying that the Jentic search-load-execute path itself works end-to-end.

Intent-based discovery

Agents search Jentic for natural-language intents like echo an http request or test a 500 error, and Jentic returns the matching httpbin endpoints with input schemas attached.

Time to first call

Direct integration: under 10 minutes since there is no auth. Through Jentic: under 5 minutes — useful as the first end-to-end smoke test of the Jentic SDK in any new agent.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Mockaroo

Generates realistic fake data and mock REST endpoints rather than echoing requests

Choose Mockaroo when the agent needs to test against realistic synthetic payloads, not just request echoes.

Alternative

LambdaTest

Cloud-based cross-browser and end-to-end test platform for richer integration testing

Choose LambdaTest when the agent needs full end-to-end browser tests rather than HTTP-level echo verification.

Complementary

Sentry

Capture and triage real client errors that surface during httpbin-driven tests

Pair with Sentry when test failures should also be reported to a production-grade error monitoring service.

FAQs

Specific to using httpbin.org API through Jentic.

What authentication does httpbin require?

httpbin.org has no authentication on its own — it is a public service. Some endpoints like /basic-auth and /bearer return 401 unless you supply credentials, but those credentials are echoed for testing only and not validated against any account.

Can I use httpbin to test retry logic for AI agents?

Yes. Hit /status/{codes} with values like 429, 500, or 503 to trigger deterministic failures, and /delay/{delay} for slow responses. Together these cover the most common retry and circuit-breaker test paths.

What are the rate limits for httpbin.org?

httpbin.org is a public service with no documented per-key limits. For high-volume testing, run kennethreitz/httpbin locally with docker run -p 80:80 kennethreitz/httpbin to avoid rate-limit risk and shared-instance variance.

How do I use httpbin through Jentic to debug an agent?

Search Jentic for echo an http request, load the /anything operation on httpbin, and execute. The response shows exactly which headers, query parameters, and body the agent sent — useful for diagnosing tool-call construction bugs.

Does httpbin support testing compressed responses?

Yes. /gzip, /deflate, and /brotli return responses encoded with the named compression so the client's decompression handling can be verified end-to-end.

Is httpbin free to use?

Yes. httpbin.org is free and open-source. The same service can also be self-hosted via the kennethreitz/httpbin Docker image for fully isolated CI usage.
