01 / INPUT**Scoped URL + bounded request**

02 / YOUR WORKFLOW**Inspect status → read outcome → adjust**

03 / OUTPUT**A recorded retrieval outcome**

## Keep the right fields.

Workflow field map

| Field / step | Input | Rule |
| --- | --- | --- |
| Budget | maxPages + maxCredits | Stop before exceeding either ceiling. |
| Recovery | Saved request and retry hints | Do not create duplicate requests blindly. |
| Failure | Page journal + warnings | Failed visits count; inspect before reauthorizing. |

## Before you use the output

Use the supported source path and documented limits. The current product does not offer CAPTCHA solving, browser fingerprint controls or guaranteed access to blocked sources.

## Check one record first.

Start with the smallest useful scope. Compare the returned record with its source, confirm variant identity and inspect missing fields before applying the mapping to a larger dataset.

Keep extraction warnings and the retrieval timestamp with downstream output. When a required field is missing, leave it unresolved or return to the source; do not fill it from an assumption.
