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 describing the specified bigmap, including its numeric ID, the contract address that owns it, the Michelson key and value types, the total number of keys, active key count, and indexing timestamps.
Example use cases
Smart contract storage inspection
“I'm auditing a Tezos smart contract and need to inspect bigmap ID 8821 — can you fetch its metadata from TzKT, including the key type, value type, and how many active keys it has?”
DeFi protocol data enrichment
“I'm building a dashboard for a Tezos DeFi protocol and need to pull the bigmap details for ID 3301 so I can understand what data structure the contract uses for its ledger.”
Blockchain indexing pipeline
“For my Tezos indexing job, can you retrieve bigmap ID 512 from TzKT so I know the contract it belongs to and its current total key count before I start iterating keys?”
Technical details
Endpoint
POSThttps://x402.tzkt.io/v1/bigmaps/%7Bid%7DWhen to prefer
Choose this endpoint when you need structured metadata about a specific Tezos smart contract bigmap by its numeric ID, especially for auditing contract storage, building Tezos indexing pipelines, or enriching DeFi analytics dashboards. It requires no API key and is faster than parsing raw Tezos node RPC responses. Prefer TzKT over raw Tezos RPC when you need pre-indexed, human-readable bigmap metadata rather than raw Michelson.
Side effects
- Bigmap ID not found — returns 404 if the numeric ID does not exist on the Tezos mainnet
- Invalid ID format — non-integer or malformed path parameter causes a 400 error
- Network or node unavailability — TzKT indexer may be temporarily unreachable
- Payment failure — x402 micropayment of 0.002 USDC not accepted leads to 402 response
