How much does zuzu.codes cost?

The starter track is free — read all lessons and practice for free. Full access to every track (current and future) is $14.99/month. Cancel anytime.

How long does each track take?

Each track is designed as a 30-day challenge — one lesson per day, about 15 minutes each. Go at your own pace, but the structure is built around daily consistency.

What's the lesson format?

Each lesson is a student-teacher dialogue with code examples, followed by a hands-on code challenge in an in-browser editor. You read, you understand, then you write real code.

Do I need prior coding experience?

Our beginner track starts from absolute zero — no prior experience needed. Advanced tracks build on earlier ones, and the platform tells you exactly where to start.

How is zuzu.codes different from freeCodeCamp or Codecademy?

zuzu.codes uses a structured 30-day track format with dialogue-based teaching, an in-browser code editor, and gamification (XP, streaks, progress tracking). The format builds genuine understanding through daily practice.

Direct HTTP — Automation Mastery

Day 9 · ~11 min●

Composio covers many services but not all. For an endpoint without a tool, you fall back to direct HTTP — the universal escape hatch. The library: requests.

python

import requests

r = requests.get("https://httpbin.org/get", timeout=10)
print(r.status_code)
print(r.json().get("url"))

Three pieces: a method (get/post/put/delete), a URL, optional kwargs (timeout, headers, params, json).

Why timeout=10?

Default requests timeout is infinite — a script that hangs forever on a flaky endpoint. Always pass an explicit timeout. 10 seconds is a reasonable default for a single API call; tune up or down based on the endpoint's typical latency.

And r.json() — what's the difference from json.loads(r.text)?

r.json() does both: parses the body and decodes the encoding. It raises JSONDecodeError on non-JSON. json.loads(r.text) does the same but you'd need to handle encoding edge cases yourself. Reach for r.json() first; only drop down to r.text for non-JSON responses or debugging.

Direct HTTP — the universal escape hatch

When you need it

Endpoint has no Composio tool
You need an HTTP capability Composio doesn't expose (custom headers, redirects, file upload streaming)
You're calling your own service
You're prototyping against a third-party API before there's a Composio shim

The shape

python

import requests

r = requests.get("https://api.example.com/items",
                 params={"page": 1},
                 headers={"Authorization": "Bearer ..."},
                 timeout=10)

r.raise_for_status()         # raises HTTPError on 4xx/5xx
data = r.json()              # parse body as JSON

Four kwargs cover 95% of needs:

Kwarg	Purpose
`params`	Query string — `?key=value` pairs
`headers`	HTTP headers (auth, content-type, custom)
`json`	Request body — auto-encoded as JSON, sets `Content-Type`
`timeout`	Seconds before raising `Timeout`

Always set a timeout

Default is no timeout. A flaky endpoint can hang your script indefinitely. Always set one:

python

requests.get(url, timeout=10)        # bare-minimum hygiene
requests.get(url, timeout=(3, 10))   # (connect, read) — even better

Reading the response

python

r.status_code           # int: 200, 404, 500
r.headers               # dict-like: {'Content-Type': 'application/json', 'X-RateLimit-Remaining': '...'}
r.json()                # parse body as JSON; raises on non-JSON
r.text                  # body as string
r.content               # body as bytes (for binary)

Status code reflexes

python

# Reflex 1: raise_for_status() turns 4xx/5xx into exceptions you can `except` on
r.raise_for_status()

# Reflex 2: handle JSON-decode errors
try:
    data = r.json()
except ValueError:        # JSONDecodeError is a subclass
    print(f"non-JSON response: {r.text[:200]}")
    raise

POSTing JSON

python

r = requests.post(
    "https://api.example.com/items",
    json={"name": "foo", "value": 42},   # auto-encoded, sets Content-Type
    headers={"Authorization": "Bearer ..."},
    timeout=10,
)

Use json= (auto-encoded) over data=json.dumps(...) — fewer ways to typo the content-type.

Pyodide note

Direct requests calls don't run in the browser-Pyodide context — only in the Sandbox. This and every HTTP lesson is a sandbox-pro lesson; it won't run in the in-browser interpreter.
