Bittensor Subnet Registration Cost History
x402
Bittensor Subnet Registration Cost History is a paid API for AI agents from api.carbon-cashmere.de, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Returns hourly NeuronRegistered event counts and current burn-cost per Bittensor subnet, enabling prediction of cheap-registration windows.
Price / call$0.01

StatusUnknown
How this service works
Hourly Bittensor subnet registration activity (NeuronRegistered event count per subnet) + current burn-cost per subnet. Useful for predicting cheap-registration windows.
Output
Returns hourly NeuronRegistered event counts per Bittensor subnet alongside the current burn cost (TAO) for each subnet, allowing identification of low-activity registration windows where costs are minimized.
Example use cases
Example prompt
“Show me the hourly NeuronRegistered event counts and current burn costs for all Bittensor subnets so I can figure out the cheapest window to register a new neuron.”
Technical details
Endpoint
GEThttps://api.carbon-cashmere.de/v1/bittensor-derivatives/registration-cost-historyWhen to prefer
Choose this endpoint when you need historical and current Bittensor subnet registration cost data to time a neuron registration cheaply, or when monitoring registration pressure across subnets over time. Prefer over general Bittensor metagraph snapshots when the specific goal is cost-timing for registration.
Side effects
- Invalid or unknown netuid returns 404 or empty data
- Subtensor node connectivity issues causing stale or missing data
- Rate limiting if called too frequently
- Malformed request parameters return 400 bad request
