How this service works
TzKT is a comprehensive Tezos blockchain indexer API. Access blocks, operations, accounts, contracts, bigmaps, delegates, tokens and network stats through a fast REST API. No signup or API key required.
Output
Returns a JSON object representing the current decoded storage of the specified Tezos smart contract, including all top-level fields such as bigmap IDs, addresses, nat/int values, maps, and nested records as they exist on-chain at the latest indexed block.
Example use cases
Inspect FA2 token contract state
“Pull the current storage for the Tezos FA2 token contract at KT1PWx2mnDueood7te3QdfAAB1LHpbE3hy4o — I need to see the ledger bigmap ID and the admin address it's currently set to.”
Verify contract admin address
“Check the storage of the Tezos contract KT1GRSvLoikDsXujKgZPsGLX8k8VvR2Tq95b and tell me who the current administrator is.”
Monitor DEX reserve values
“Fetch the storage for the Quipuswap DEX contract at KT1Qm7RbGppCVBKiHYSd5Bvv8gNvJCVMEBD9 on Tezos — I want to see the current token and XTZ reserve amounts stored in it.”
Technical details
Endpoint
POSThttps://x402.tzkt.io/v1/contracts/%7Baddress%7D/storageWhen to prefer
Use this endpoint when you need the full decoded current storage of a Tezos smart contract indexed by TzKT, especially when you want a structured JSON view without writing RPC calls to a Tezos node directly. Prefer this over raw Tezos node RPC when you want human-readable decoded Michelson storage rather than raw binary, and when you need no API key overhead. Ideal for agents inspecting DeFi protocols, NFT contracts, DAO governance contracts, or any KT1 address on Tezos mainnet.
Side effects
- Invalid or non-existent contract address returns a 404 error
- Contract address that is not a smart contract (e.g. an implicit account) returns an error or empty response
- Malformed address format causes a 400 bad request
- Network or indexer lag may mean storage is slightly behind chain head
- Payment failure via x402 protocol results in 402 response and no data returned
