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
An array of Tezos block objects, each containing block-level metadata such as the block level (height), timestamp, proposer address, and potentially balance fields denominated in the requested quote currency. Results are paginated and ordered according to the specified sort parameters.
Example use cases
Monitor baker block production
“Fetch the last 50 Tezos blocks proposed by tz1abc123... sorted by level descending so I can see how active that baker has been recently.”
Audit blocks in a time window
“Get me all Tezos blocks from January 1 2024 to January 7 2024 so I can analyze on-chain activity during that week.”
Track latest chain head
“What is the most recently produced Tezos block? Give me the top 1 block sorted by level descending with balance fields in USD.”
Technical details
Endpoint
GEThttps://x402.tzkt.io/v1/blocksWhen to prefer
Choose this endpoint when you need structured, indexed access to Tezos block history with flexible filtering by level, timestamp, or proposer — especially useful for monitoring baker activity, auditing chain history, or building block explorers. Prefer it over raw node RPC calls because it provides a fast REST interface with sorting, pagination, and filtering without requiring a synced node or API key.
Side effects
- Invalid filter syntax for level or timestamp fields returns a 400 Bad Request
- Unsupported quote currency results in an error response
- Limit exceeding 10000 is rejected
- No blocks matching the given filters returns an empty array
- Network unavailability or indexer lag may cause stale or missing data
- Payment failure (x402 protocol) blocks access before query is executed
