GraphQL
A query language for APIs
An API style where the client asks for exactly the fields it needs in one query, instead of many fixed REST endpoints. Servers expose a schema; clients send queries and mutations.
Concrete example
A single GraphQL query can ask for a user and their latest orders in one round trip.
Why it matters
Common in modern product APIs—and easy for agents to over-fetch or under-specify.
