How this service works
Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data
Output
Returns a JSON object with four fields: finished_indexing (boolean, true if full indexing is complete), indexed_blocks_ratio (number 0–1 representing fraction of blocks indexed), finished_indexing_blocks (boolean, true if all blocks are indexed), and indexed_internal_transactions_ratio (number 0–1 for internal transaction indexing progress).
Example use cases
Monitor chain sync before querying
“Before I run a query against the Optimism chain on Blockscout, can you check if it's fully indexed? I need to know the indexed blocks ratio and whether internal transactions are done.”
Alert when indexing is complete
“Watch the Blockscout indexing status for chain ID 137 (Polygon) and let me know when finished_indexing flips to true.”
Debug missing transaction data
“I'm not seeing some transactions on the Blockscout explorer for Base — can you check the indexing status to see if it's still syncing blocks or internal transactions?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/main-page/indexing-statusWhen to prefer
Use this endpoint when you need to verify whether a specific blockchain's data on Blockscout is fully indexed before querying transactions, addresses, or tokens — especially useful to avoid incomplete results in newly added or re-syncing chains. Prefer this over general blockchain node status checks when you are specifically working within the Blockscout ecosystem.
Side effects
- Invalid or unsupported chain_id returns a 404 or error response
- Chain not yet onboarded to Blockscout returns empty or error
- Network timeout if Blockscout infrastructure is temporarily unavailable
- Ratio values may show 0 even when indexing is in early stages, which can be misleading
