Verify cookies value

This only verifies that the cookies value is correct. To complete setup, you MUST proceed to POST /accounts and complete the configuration of the Google Flow API account using the cookies value retrieved above.

You should receive HTTP 200 if all steps above were executed properly. Proceed to POST /accounts and complete the configuration.

⚠️ Once completed, make sure to clear all browser cookies to ensure that this session will no longer be active in the browser and fully managed by API.

Configure Captcha Providers

Image and video generation requires reCAPTCHA v3 Enterprise solving.

Users receive 100 free captcha credits when adding their first Google Flow account. These credits are used automatically, so you can start generating images and videos right away without configuring any provider. Check your remaining credits via GET /accounts/captcha-providers.

After free credits are exhausted, you must configure at least one provider’s API key before using POST /images, POST /images/upscale, or POST /videos.

Supported Providers:

Provider Cost Website
EzCaptcha (Recommended) ~$2.50 per 1,000 solves ez-captcha.com
CapSolver ~$3.00 per 1,000 solves capsolver.com
YesCaptcha varies yescaptcha.com

Setup Steps:

  1. Create an account with one or more providers above
  2. Purchase credits and obtain your API key from the provider’s dashboard
  3. Configure your API key(s) using POST /accounts/captcha-providers

Recommendations:

  • We have thoroughly tested EzCaptcha and recommend it as the primary provider. Other providers will also work but may have lower success rates.
  • Configure multiple providers for redundancy (if one fails or returns rejected tokens, the API automatically retries with the next provider)
  • Each image/video generation attempt requires one captcha solve (~$2.50-$3.00 per 1,000 generations)
