Cost is predictable

Single lookup costs 1 unit. Official bulk costs 1 unit per two entries, rounded up. Enriched bulk costs 1 unit per entry.

429 is a control signal

When the quota is exhausted, wait for the number of seconds in Retry-After. Parallel retries consume shared capacity.

Corrections are reviewed

The correction form creates a private tracking reference. A submission never changes public data automatically.

Commercial terms are not implied

The public plan does not include support response guarantees, dedicated infrastructure, or bulk dataset redistribution.
