Credit
A credit is the unit of metering. Every metered response reports what it cost and what remains.

What is free
Every GET: retrieving a resource you already paid for, listing, jobs, usage,
citation styles, and exports. Reads being free is deliberate — poll and paginate
without watching the meter.
Depth dominates cost
A deep_review search costs 12× a standard one. Escalate on demand, not by default. See
depth and cost-control.
Running out
A call that cannot be paid for returns 402 insufficient_credits. Nothing is partially charged, and
no resource is created. Per-key caps fail the same way while leaving other keys working
(api-keys).
