How this service works
Recent Subtensor chain events, optionally filtered by pallet, event name, block range, or pagination. Requires TAOSTATS_API_KEY.
Output
Returns a paginated list of recent Subtensor chain events, each including the pallet name, event name, block number, and associated event data/metadata, filtered by any specified pallet, event name, or block range.
Example use cases
Monitor Bittensor staking activity
“Show me the latest SubtensorModule staking events on the Subtensor chain — get up to 50 events on page 1 so I can see what's happening with staking right now.”
Track ExtrinsicSuccess events for auditing
“Fetch recent ExtrinsicSuccess events from the System pallet on the Subtensor blockchain, page 1, limit 100, so I can audit which extrinsics completed successfully.”
Investigate recent token transfers
“Get me the most recent Transfer events from the Balances pallet on the Subtensor chain, up to 50 at a time, so I can track token movement on Bittensor.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/subtensor-events?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, filterable on-chain event data from the Bittensor/Subtensor blockchain, especially when you want to monitor specific pallets (SubtensorModule, Balances, System) or event types (Transfer, ExtrinsicSuccess) with pagination support. Prefer this over raw block explorers when you need programmatic access to event streams.
Side effects
- Missing or invalid TAOSTATS_API_KEY returns 401 Unauthorized
- Invalid pallet name returns empty result set or 400 error
- Page number out of range returns empty results
- limit exceeding 100 is rejected with validation error
- Subtensor node or TaoStats API downtime causes 502/503 errors
