A small, dependency-free Python client and CLI for Cloudflare Turnstile tokens, backed by the Clearance API.

It finds the sitekey on a page, gets you a ready-to-submit cf-turnstile-response value in about 451 milliseconds, and hands back the browser identity the token was earned with - so your follow-up request presents the same TLS and HTTP/2 fingerprint and the token is not thrown away.

• Free credits on sign-up. No card, no trial countdown - create an account and get started.
• $0.40 per 1,000. $0.00040 a solve. Failed solves are refunded in full.
• 451ms average Turnstile solve, with a live figure on the status page.
• No runtime dependencies. Standard library only, Python 3.8+.
• Sitekey discovery built in. Point it at a page; it finds the key.

Published per-1,000 rates for Cloudflare Turnstile, gathered from each provider's own pricing page:

At $0.40 that is roughly a third of what the field charges, without giving up solve time - Turnstile averages 451ms here against a published field average of about 8 seconds.

The most common Turnstile integration bug is not the solve. The solve works, the token comes back, the request goes out - and Cloudflare rejects it.

The reason: a Turnstile token is bound to the browser that earned it. The User-Agent, the TLS handshake and the HTTP/2 settings present when the widget was solved are baked into the token. Replay it from a different client and the edge treats it as if you had never solved anything.

Most clients return a bare token string and leave you to guess the rest. This package returns the token together with the identity that earned it:

bundle = client.solve("https://example.com/login")

bundle.token        # the cf-turnstile-response value
bundle.user_agent   # the exact User-Agent
bundle.profile_id   # e.g. "brave151-windows-b0ddf2db"
bundle.emulation    # TLS + HTTP/2 fingerprint block
bundle.replay_headers()   # headers ready to send
bundle.form_fields()      # form fields ready to POST

Send all of it and the token clears. Send the token alone and you are guessing.

pip install turnstile-token

Or straight from source:

git clone https://github.com/<you>/turnstile-token.git
cd turnstile-token
pip install .

No dependency resolution is needed - the package installs nothing else.

Create an account to get your key - it takes about a minute and comes with free credits:

Then export the key from Dashboard > Settings:

export CLEARANCE_API_KEY="your_key_here"

turnstile-token solve --url https://example.com/login
turnstile-token solve --url https://example.com/login --sitekey 0x4AAAAAAAxxxx --action login
turnstile-token discover --page https://example.com/login
turnstile-token verify --token 0.mF74dQpX2rC8vT1kLzB6hN3sYwA9eJgUiO5
turnstile-token balance

The token is printed to stdout; progress goes to stderr, so the output is safe to pipe.

from turnstile_token import TurnstileClient

client = TurnstileClient.from_env()
bundle = client.solve("https://example.com/login")

print(bundle.token)          # submit as cf-turnstile-response
print(bundle.profile_id)     # the browser that solved it

# replay with the identity that earned it
headers = bundle.replay_headers()
fields = bundle.form_fields()

Pass a sitekey explicitly when you already have one:

bundle = client.solve("https://example.com/login", sitekey="0x4AAAAAAAxxxx", action="login")

Two calls, no SDK, no browser:

# 1. create the task
curl -s https://api.clearance.sh/createTask \
  -H 'content-type: application/json' \
  -d '{
    "clientKey": "YOUR_API_KEY",
    "task": {
      "type": "AntiTurnstileTask",
      "websiteURL": "https://example.com/login",
      "websiteKey": "0x4AAAAAAAxxxx"
    }
  }'

{ "errorId": 0, "status": "idle", "taskId": "0f5a5b6c-9a5a-4a1e-9d3f-2b8c5a9e4d71" }

# 2. read the result (sleep ~500ms first, then poll every 200-300ms)
curl -s https://api.clearance.sh/getTaskResult \
  -H 'content-type: application/json' \
  -d '{"clientKey": "YOUR_API_KEY", "taskId": "0f5a5b6c-9a5a-4a1e-9d3f-2b8c5a9e4d71"}'

{
  "errorId": 0,
  "taskId": "0f5a5b6c-9a5a-4a1e-9d3f-2b8c5a9e4d71",
  "status": "ready",
  "solution": {
    "token": "0.mF74dQpX2rC8vT1kLzB6hN3sYwA9eJgUiO5",
    "type": "turnstile",
    "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36",
    "profileId": "brave151-windows-b0ddf2db",
    "emulation": { "alpn": ["h2", "http/1.1"], "key_shares": ["X25519MLKEM768", "X25519"] }
  }
}

Either form of authentication works on both calls: put the key in the body as clientKey, or send an X-Private-Key header. Prefer the header if your client logs outbound requests, because headers are far easier to redact than bodies.

You do not always have the sitekey to hand. If it is not already in your config, pull it off the page:

from turnstile_token import SitekeyScanner, discover_sitekey, discover_sitekeys, read_page

html = read_page("https://example.com/login")
sitekey = discover_sitekey(html)     # most likely match, or None
every = discover_sitekeys(html)      # all unique matches, best first

The scanner recognises the three shapes Turnstile keys actually appear in:

<div class="cf-turnstile" data-sitekey="0x4AAAAAAAabc123"></div>

turnstile.render(el, { sitekey: "0x4AAAAAAAabc123" });

/cdn-cgi/challenge-platform/...?k=0x4AAAAAAAabc123

Each match carries a confidence score and a context snippet, so a page with several widgets can be told apart:

scanner = SitekeyScanner()
for hit in scanner.scan(html):
    print(hit.value, hit.source, hit.confidence, hit.context)

From the shell:

turnstile-token discover --page https://example.com/login

A cheap local check for pipeline wiring mistakes - truncated tokens, shell-quoting damage, tokens from the wrong field:

from turnstile_token import verify_token

report = verify_token("0.mF74dQpX2rC8vT1kLzB6hN3sYwA9eJgUiO5")
print(report.plausible)   # True
print(report.length)      # 37
print(report.segments)    # 2
print(report.reasons)     # ["shape looks correct"]

From the shell:

turnstile-token verify --token 0.mF74dQpX2rC8vT1kLzB6hN3sYwA9eJgUiO5

{
  "token": "0.mF74dQpX2rC8vT1kLzB6hN3sYwA9eJgUiO5",
  "plausible": true,
  "length": 37,
  "segments": 2,
  "reasons": ["shape looks correct"]
}

Exit code 0 when the shape is plausible, 1 when it is not. This checks the shape only - only Cloudflare can say whether a token is accepted.

A ready result is turned into a ReplayBundle:

The emulation block is what makes the replay work:

"emulation": {
  "alpn": ["h2", "http/1.1"],
  "curves_list": "X25519MLKEM768:X25519:P-256:P-384",
  "key_shares": ["X25519MLKEM768", "X25519"],
  "min_tls_version": "1.2",
  "max_tls_version": "1.3",
  "permute_extensions": true,
  "http2": {
    "settings_order": [1, 2, 4, 6],
    "headers_pseudo_order": ["m", "a", "s", "p"]
  }
}

Three helpers package it for you:

bundle.identity          # {"userAgent", "profileId", "emulation"}
bundle.replay_headers()  # headers with the correct User-Agent
bundle.form_fields()     # {"cf-turnstile-response", "g-recaptcha-response"}

Send the follow-up request with all of it:

bundle = client.solve(url)

final = post(
    url,
    headers=bundle.replay_headers(),
    data=bundle.form_fields(),
    # ... and a TLS/HTTP2 stack configured from bundle.emulation
)

A client that checks only response.ok and replays the token with a default HTTP library will present a different handshake, and the token is thrown away. That is the failure people blame on the service.

bundle = client.solve(
    "https://example.com/login",
    sitekey="0x4AAAAAAAAjq6WYeRDKmebM",
    action="login",
    proxy="http://user:pass@host:port",
)

Every task accepts an optional proxy so the solve happens from your own exit IP, which matters when the target is IP-sensitive:

client = TurnstileClient(key, proxy="http://user:pass@host:port")

This package also accepts the shorter host:port:user:pass form and normalises it. Leave the proxy off and the solve uses Clearance's egress instead.

Everything is asynchronous. /createTask returns an id immediately; /getTaskResult returns the solution once a node has produced it.

• Sleep about 500ms after creating the task.
• Then poll every 200-300ms. Sooner mostly buys you processing responses; slower adds latency that has nothing to do with the service.
• A result lives for five minutes, and reading it does not consume it. The same solution comes back until it expires, so a retry after a dropped connection is free and you never lose a solve you already paid for.
• After five minutes the id is gone and returns ERROR_TASKID_INVALID.
• GET /status takes no key at all, so a monitor can watch capacity without holding a credential.

The TurnstileClient does all of this for you:

bundle = client.poll(task_id)          # 500ms grace, then 250ms polls

Or drive it yourself:

task_id = client.create({"type": "AntiTurnstileTask", "websiteURL": url, "websiteKey": sitekey})
time.sleep(0.5)
while True:
    data = client.result(task_id)
    if data["status"] == "ready":
        break
    if data["status"] == "failed":
        raise RuntimeError(data["errorCode"])
    time.sleep(0.25)

Seven codes cover everything the API can refuse or fail to do. Three are worth retrying, four are not.

Protocol errors arrive as HTTP 200 with errorId: 1 - that is deliberate, so a client that only checks the status code will happily read a failed solve as a success. Branch on the body, check errorId, then switch on errorCode.

This package models all of that:

from turnstile_token import TurnstileError, RETRYABLE_CODES

try:
    bundle = client.solve(url)
except TurnstileError as exc:
    if exc.code == "ERROR_KEY_DOES_NOT_EXIST":
        ...                       # fix the key, do not retry
    elif exc.retryable:
        ...                       # back off and try again
    else:
        raise                     # a bug in the request

TurnstileClient already applies exponential backoff to retryable codes and prefers Retry-After over its own guess whenever the server sends one. The retry budget is capped so an incident cannot turn into a silent hang.

• $0.40 per 1,000 solves - $0.00040 each.
• A failed solve is refunded in full and is not billed.
• Capacity is checked before any money moves. ERROR_NO_SLOT_AVAILABLE never charges you at all.
• No subscription, no minimum spend. Pay for what clears.

Check your balance without touching anything else:

turnstile-token balance
# 303.43519

turnstile-token solve    --url URL [--sitekey KEY] [--action NAME]
turnstile-token discover --page URL
turnstile-token verify   --token TOKEN
turnstile-token balance
turnstile-token batch    FILE [--sitekey KEY]

Global flags: --api-key, --proxy, --timeout, --retries, --quiet, --verbose, --version.

Exit codes: 0 success, 1 solve failed, 2 usage or credential problem.

python examples/batch_urls.py targets.txt > results.json

One URL per line; blank lines and # comments are skipped. A failure on one URL never aborts the batch - the error is recorded next to its URL:

[
  { "url": "https://a.example/", "ok": true,  "token": "0." },
  { "url": "https://b.example/", "ok": false, "error": "ERROR_CAPTCHA_UNSOLVABLE: no token produced" }
]

The CLI has the same thing built in:

turnstile-token batch targets.txt

How much does a solve cost? $0.40 per 1,000 - $0.00040 each. Failed solves are refunded. New accounts start with free credits.

How fast is a solve? Turnstile averages 451ms. The live figure is published on the status page without needing an account.

Do I need a browser? No. Two REST calls, no SDK, nothing to install on your side.

Can I use my own proxy? Yes - every task accepts an optional proxy. Leave it off and the solve uses Clearance's egress instead.

Why did my token fail even though the solve succeeded? Almost always the identity. The token is bound to the User-Agent and TLS handshake that earned it. Replay bundle.replay_headers() and a stack configured from bundle.emulation, not your default HTTP client.

How long does a Turnstile token last? Treat it as a single-use value. It is valid for the submission it was earned for and is not meant to be stored or replayed across sessions.

What happens if a solve fails? You are refunded in full and not billed. The code is ERROR_CAPTCHA_UNSOLVABLE and it is retryable.

Is there a public status page? Yes - clearance.sh/status publishes solve activity, queue depth and node capacity, refreshing every 30 seconds, and the same figures are available as JSON with no API key.

How do I get volume pricing? Unlimited plans are arranged directly on request.

Free credits on sign-up, no card required.
