Documented steps

  1. Check what CAPTCHAs the session currently faces: GET https://api.steel.dev/v1/sessions/captchas/status/{sessionId} (header steel-api-key) — returns detected CAPTCHAs with task/page identifiers and type
  2. Trigger a solve: POST https://api.steel.dev/v1/sessions/captchas/solve/{sessionId} with taskId, url, or pageId identifying the target CAPTCHA
  3. For image-to-text CAPTCHAs: POST https://api.steel.dev/v1/sessions/captchas/solve-image/{sessionId} with required imageXPath and inputXPath (optional url)
  4. Poll the status endpoint until the solve reports success, then continue navigation in the same session
  5. Mapped CAPTCHA types: recaptchaV2, recaptchaV3, turnstile, image_to_text
