GET /api/chain/storage

live

Read one 32-byte storage slot from a contract, the raw state under whatever the source code calls it. Returns the word as hex plus three readings of the same bytes - unsigned integer, address (low 20 bytes) and boolean - because a slot is untyped on chain and only the caller knows which it meant.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
