How this service works

Output
Returns a paginated list of blockchain transactions matching the specified filters, including transaction hashes, statuses, types, methods, block numbers, and timestamps for each transaction on the target chain.
Example use cases
Monitor pending transactions on a chain
“Show me all pending transactions on chain 137 (Polygon) right now — I want to see what's in the mempool.”
Audit failed transactions by block
“List the failed transactions from block 19500000 on chain 1 so I can investigate what went wrong in that block.”
Browse recent token transfer history
“Get me the last 10 token transfer transactions on chain 8453 (Base), filtered by type 'token_transfer', so I can track recent activity.”
Technical details
Endpoint
GEThttps://api.k8s-dev.blockscout.com/:chain_id/api/v2/transactionsWhen to prefer
Use this endpoint when you need to list, browse, or filter blockchain transactions on a specific EVM-compatible chain using the Blockscout explorer infrastructure. It is ideal for paginated transaction browsing, filtering by type or status, and querying by block number or hash. Prefer this over raw RPC calls when you want pre-indexed, human-readable transaction metadata without running your own node.
Side effects
- Invalid or unsupported chain_id returns 404 or empty result
- Invalid filter or type enum value may return 400 bad request
- Pagination parameters out of range may return empty list
- Network unavailability of the k8s-dev instance returns 503
- Missing required type or method parameters returns validation error
