How this service works

Example use cases
Example prompt

Technical details
Endpoint
GEThttps://x402.tzkt.io/v1/operations/originationsWhen to prefer
Use this endpoint when you need to query historical smart contract deployment (origination) events on the Tezos blockchain, filter by sender or initiator, or paginate through contract creation history. Prefer this over generic block explorers when you need structured JSON output suitable for programmatic processing without requiring an API key.
Side effects
- Invalid sender or initiator address format returns an empty array or 400 error
- Invalid sort field name causes a 400 Bad Request
- Payment failure (x402) prevents access if USDC balance is insufficient
- Offset beyond total results returns empty array
- Timestamp format errors result in filter being ignored or 400 error
