Glossary

The words the reference, the console and your invoice use, each with one meaning.

Terms

Request
Any call to a /v1 endpoint. Your plan includes a number of requests each day and each UTC month.
Verification
The one metered unit. Every successful request to /v1/titles/{titleRef}/sources spends exactly one, whether we check again or already hold the answer; a refused or failed one spends none, and no other endpoint spends one.
Allowance
How many requests (each day and each UTC month) and verifications (each day and each billing period) your plan includes.
Spending limit
The most you allow extra verifications past your allowance to cost in a billing period. You set it in the console.
Flood limit
A ceiling on calls from one address, counted before a key is read. See the rate limits guide.
Title reference
A title's public id, such as mv_3RGB99HMTQ, or an outside id that /v1/lookup resolves.
Cursor
An opaque string that fetches the next page of a list. See the pagination guide.
Change feed
/v1/changes: what changed in the catalogue since a point you name, in order.
Demo key
The public key the reference's Try-it uses: daily rotation, a fixed set of endpoints, tight limits.
