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 array of Tezos smart contract objects. Each object includes contract address, kind (e.g. delegator, smart_contract), balance in mutez, and other on-chain metadata depending on the 'select' fields specified. Results are paginated and sorted per request parameters.
Example use cases
Discover high-value DeFi contracts
“Find me the top 20 Tezos smart contracts with the highest balances — I want to see their addresses and current holdings to identify the biggest DeFi protocols on-chain.”
Audit FA2 token contracts
“List all FA2 token contracts on Tezos, up to 100 results, sorted by balance — I'm building a report on active token issuers and need their contract addresses.”
Monitor contract landscape changes
“Give me a snapshot of up to 500 Tezos contracts sorted by their creation order, paginated from offset 0, so I can track new smart contract deployments on the network.”
Technical details
Endpoint
GEThttps://x402.tzkt.io/v1/contractsWhen to prefer
Use this endpoint when you need to enumerate, filter, or paginate through Tezos smart contracts at the network level without requiring authentication. It is ideal for blockchain analytics, DeFi research, contract discovery, and on-chain auditing tasks. Prefer this over individual contract lookup endpoints when you need a list view rather than details about a single known contract address.
Side effects
- Invalid 'kind' enum value returns empty results or 400 error
- Limit exceeding 10000 returns a validation error
- Malformed balance filter syntax (missing operator suffix) returns 400
- Network congestion may increase response latency
- Requesting too many fields via 'select' may cause partial data return
