Bittensor Subnet Registration API
x402
Bittensor Subnet Registration API is a paid API for AI agents from golf-evm-math.x402-evm-math.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-28).
Returns registration cost (burn in TAO), free slot counts, prune risk, and incentive thresholds for all Bittensor subnets, refreshed every 30 minutes.

How this service works
Exact EVM address, calldata, Uniswap V2/V3 and impermanent-loss math. Pay per call in USDC on Base via x402.
Output
Returns a JSON object with the network name (bittensor-finney), an array of subnet objects each containing: netuid, total UIDs, burn cost in TAO, max UIDs, number of protected slots, prune bar incentive threshold, blocks until next unprotect, and median miner incentive. Also includes age_seconds indicating how old the cached data is (refreshed every 30 minutes).
Example use cases
Cheapest subnet registration scouting
“Which Bittensor subnets currently have the lowest burn cost in TAO to register, and do any of them still have free slots available?”
Prune risk assessment for active miners
“I'm a miner on Bittensor subnet 18 — what incentive do I need to maintain to avoid being pruned, and how many protected slots are there?”
Automated registration cost monitoring
“Check all Bittensor subnet registration fees and alert me if any subnet's burn cost drops below 0.005 TAO or opens up free registration slots.”
Technical details
Endpoint
GEThttps://golf-evm-math.x402-evm-math.workers.dev/bittensor/subnets?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive, low-latency snapshot of registration economics across all Bittensor subnets simultaneously — burn costs, free slots, and prune thresholds in one call. Prefer this over on-chain queries when you don't need real-time precision and want to avoid RPC overhead. Ideal for agents making registration decisions, monitoring subnet health, or comparing subnet economics programmatically.
Side effects
- Stale data: cache may be up to 30 minutes old, real-time registration windows may differ
- Network outage: if Bittensor Finney network is unreachable, endpoint may return error or empty subnet list
- Payment failure: x402 payment of $0.015 USDC not fulfilled results in 402 response
- Missing subnet: newly created subnets may not appear until next cache refresh
- Rate limiting: excessive calls may be throttled by the Cloudflare Worker
