getCoverageCells

The Coverage page for a whole state (stateAbbr, e.g. TX) or up to 300 named counties (countyFips, five digits): one row per county and signal type (FORECLOSURE, PREFORECLOSURE, PROBATE, PREPROBATE, TAX_DELINQUENCY, CODE_VIOLATION). status: LIVE, IN_PROGRESS (we are building it; expectedBy is the promise on your own request), WAITING_ON_COUNTY (we asked the county for its records), NOT_AVAILABLE (notAvailableReason), NOT_REQUESTED. delayed: live but its source is failing; partial: delivering through a backstop, not live. delivered30d counts records in the last 30 days.

Variables

The example sends only what the schema requires. Some operations also need one of several optional variables (one filter or another, say); the description above says which.

stateAbbrString

countyFips[String!]

Response

What comes back under data: a list shows as one entry, and a value as its type.

Errors

400unknown_variable

A variable the operation does not declare. A typo is refused rather than silently dropped.

401unauthorized

No bearer header, or the key is invalid or revoked.

403insufficient_scope

The key lacks the scope the operation requires.

403forbidden

A referenced record does not exist, was deleted, or is outside your organization. The gateway cannot tell those apart.

Behaviour

A read. It rejects an Idempotency-Key header with 400 bad_request.
