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 delegation operation objects, each containing fields such as operation hash, block level, timestamp, sender address, new delegate address, previous delegate address, and operation status. The array is paginated and ordered according to the specified sort and offset parameters.
Example use cases
Track baker delegation inflows
“Get me all Tezos delegation operations where the new delegate is tz1aRoaRhSpRYvFdyvgWLL6TGyRoGF51wDjM, limit to 50 results sorted by most recent, so I can see who's been delegating to this baker.”
Audit wallet delegation history
“Pull the full delegation history for Tezos address tz1VSUr8wwNhLAzempoch5d6hLRiTh8Cjcjb — I want to see every baker it ever delegated to, sorted chronologically.”
Monitor delegations at specific block
“Fetch all Tezos delegation operations that happened at block level 5000000 so I can audit what staking activity occurred at that point in the chain.”
Technical details
Endpoint
GEThttps://x402.tzkt.io/v1/operations/delegationsWhen to prefer
Choose this endpoint when you need to query historical or recent Tezos delegation operations with flexible filtering by account address, baker, block level, or timestamp. It is ideal for auditing delegation histories, tracking baker inflows, or monitoring staking behavior on Tezos without requiring API key signup. Prefer alternatives if you need Ethereum or other chain delegation data.
Side effects
- Invalid sender or delegate address format returns empty array or 400 error
- Requesting beyond available pagination depth may return empty array
- Unsupported sort field values may return 400 bad request
- Network or indexer downtime returns 5xx error
- Payment failure via x402 protocol blocks the request before reaching the indexer
