How this service works
Professional crypto market intelligence. Real-time prices, signals, and market scoring.
Output
A JSON object containing an array of events (each with event_id, event_idx, and module_id), the total event_count, and the queried block_number — e.g. 120 events across System and other modules for block 8204514.
Example use cases
Example prompt
“Pull all the on-chain events from Subtensor block 8204514 — I want to see the event IDs, which modules they came from, and the total event count for that block.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/subtensor-derivatives/events/%7Bblock_number%7DWhen to prefer
Use this endpoint when you need raw on-chain event data for a specific Bittensor/Subtensor block, particularly for auditing extrinsic outcomes, monitoring module activity, or building analytics on top of Subtensor derivative events. Prefer this over generic blockchain explorers when you want a pay-per-call, programmatic JSON feed without scraping.
Side effects
- Block number not found or not yet finalized — may return empty events array or 404
- Invalid block_number format (non-integer) — likely 400 bad request
- Block number too far in the future — data unavailable
- Network connectivity issues to Subtensor node — 503 or timeout
- Payment not received — 402 Payment Required before data is returned
