Monitoring keeps a person under review for your company: once enrolled, the Bureau verifies them again every month without you asking.

Enrolling does not create a verification by itself. What it produces depends on what you already have:

• If nobody has verified that person for your company in the last 30 days, the verification is created right away.
• If you verified them recently, nothing is created and nothing is charged. The first monthly verification falls 30 days after that lookup, so you are not billed twice for the same person.

From there it is one verification per person per month. A pair stops being reviewed when you remove it, or when the person's consent expires. Read the results through the usual data endpoints.

Up to 10,000 identifiers per call; repeated identifiers collapse into one. Each identifier is answered for on its own, so one malformed CURP does not reject the batch. At most 100 failures are listed; failures_truncated tells you whether there were more.
