## When to prefer this

Use this endpoint when you need structured, indexed data about Tezos baking operations specifically — it's faster and more queryable than raw Tezos node RPC calls, requires no API key, and supports filtering by baker and block level. Prefer it over generic blockchain explorers when you need programmatic access to baker-level operation history at scale.

## Known failure modes

- Invalid baker address format returns empty array or 400 error
- Block level out of range returns empty array
- Payment failure (402) if x402 micropayment not properly attached
- Rate limiting or timeout on very large result sets
- Offset beyond total record count returns empty array

## 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 paginated array of baking operation objects from the Tezos blockchain, each containing details such as baker address, block level, block hash, timestamp, reward amounts, and other operation-specific metadata.
