# GraphQL endpoint (GET query mode)

`GET /v3/graphql`

Lightweight GET mode for development/debugging.
Disabled in production; use POST `/v3/graphql` there.
Requires `query` and optionally accepts `variables` (JSON string) and `operationName`.
Ponder LIKE filter operators reject unescaped `%` and `_` wildcard values.
Requests are analyzed before upstream execution. Defaults cap Ponder `limit` at 1,000,
`offset` at 10,000, document depth at 16, aliases at 50, `totalCount` fields at 5,
aggregate input nodes at 10,000, boolean clauses at 1,000, and list entries at 5,000.
Ponder 0.15.17 uses `limit` and `offset`, not `first` or `last`.
Each API process also shares at most 8 upstream GraphQL requests by default. A single
10-second timeout covers fetch and response streaming; redirects are rejected and decoded
JSON-object responses are capped at 5,242,880 bytes.
A non-queueing per-process query-cost bucket defaults to 100,000 units of capacity and a
25,000-unit-per-second refill. Exhaustion returns 429 before an upstream slot is acquired;
the shared per-client API rate limiter remains the outer control.
For standard GraphQL usage, use POST `/v3/graphql`.
