CAPTCHA Solving

Coordinates refer to the image you submitted, not its displayed size. Convert X by displayed width / submitted width, and Y by displayed height / submitted height. For example, X = 540 in a 1080-pixel image becomes X = 361 at 722 pixels wide. Add the image's left and top offsets for viewport clicks. These calculations assume the same uncropped image; account separately for cropping or padding and verify the challenge has not changed.

For grids, submit tiles left to right across each row, starting at the top; the tile count must equal rows multiplied by columns. Do not send both a combined image and a tile array. For Drag & Drop, preserve the input piece order because result entries correspond to those positions. Sorting pieces after submission or mixing coordinates from differently sized images can apply an otherwise valid answer incorrectly.

Compatible image-based puzzles can use a background and a separate slider-piece image. The returned destination is not a ready-to-use drag distance: your application must account for the piece's starting position and displayed scale. There is no dedicated slider solution here, and finding the target position does not guarantee the website will accept the interaction.

File limits apply to decoded bytes, but the complete JSON request has a separate 5,000,000-byte limit. Base64 adds roughly one third to the original size, and combined tiles or pieces can push the request over that limit. Send file bytes encoded as Base64 or a matching data URL, not a filename or remote image URL. Check the chosen task's file and dimension limits before submitting.

Continue checking the saved task instead of creating a replacement. A client timeout does not cancel server-side work. Preserve the original Idempotency-Key and input: an identical replay returns the saved task, while a different key can create another paid task. If submission is unconfirmed, contact support with the task ID. Poll at five-to-ten-second intervals and coordinate polling across workers.

A reservation is not the final charge. Confirmed failed tasks release it; a successful task settles against actual provider cost. A timeout can leave the outcome unresolved, so the hold remains pending review. If billingStatus is review, contact support with the ID. If it is awaiting_credit, add credit to receive the saved answer rather than paying to create another task.

Check that you applied the answer to the same, still-current challenge, with the correct image scale, tile order or piece mapping. These image solutions return answer data, not a website acceptance decision or universal verification token. Preserve the task ID and a redacted description of the mismatch for support; do not assume a ready task proves the website accepted the result.
