What causes "No cookies found for {cls.domain}" in xtekky/gpt4free?

Pass api_key (bearer token) directly to the call to skip cookie-based auth

xtekky/gpt4free · error · ValueError

No cookies found for {cls.domain}

Error message

No cookies found for {cls.domain}

What it means

Raised as ValueError by the Reka provider when no api_key was passed and get_cookies(cls.domain) returned nothing — the browser cookie store has no cookies at all for Reka's domain. Without cookies the provider cannot mint an access token via its /bff/auth/access_token endpoint.

Solutions

Pass api_key (bearer token) directly to the call to skip cookie-based auth
Log in to Reka in your default browser so g4f can read the cookies, then retry
If cookies exist in a non-default browser profile, export them to where g4f's get_cookies looks

Example fix

# before
response = client.chat.completions.create(model='reka-core', messages=msgs)  # ValueError

# after
response = client.chat.completions.create(model='reka-core', messages=msgs, api_key=os.environ['REKA_API_KEY'])

Defensive patterns

Strategy: validation

Validate before calling

from g4f.requests import get_cookies
if not os.environ.get('REKA_API_KEY') and not get_cookies('reka.ai'):
    raise SystemExit('Log in to reka.ai in your browser or set REKA_API_KEY')

Type guard

def reka_auth_ready(api_key: str | None) -> bool:
    if api_key:
        return True
    from g4f.requests import get_cookies
    return bool(get_cookies('reka.ai'))

Try / catch

try:
    result = ...create(model='reka-core', ...)
except ValueError as e:
    if 'No cookies found' in str(e):
        result = ...create(model='reka-core', api_key=os.environ['REKA_API_KEY'])
    else:
        raise

Prevention

Prefer explicit api_key in automated environments; browser cookies only work where a browser profile exists
Check cookie availability at startup on servers/containers before routing Reka traffic

When it happens

Trigger: Calling Reka without api_key on a machine whose browser has never logged in to the Reka domain, so the cookie lookup is empty.

Common situations: Fresh machine/container with no browser profile, cookies cleared, running headless in CI where no browser cookies exist.
