Bittensor Subnet Registration Lookup API
x402
Bittensor Subnet Registration Lookup API is a paid API for AI agents from golf-evm-math.x402-evm-math.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).
Returns registration burn cost in TAO, free slot count, max UIDs, and prune-bar incentive threshold for a single Bittensor subnet identified by netuid.

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 containing the subnet's netuid, current number of registered UIDs, maximum UID capacity, registration burn cost in TAO (burn_tao), the prune bar incentive threshold, and the network name (bittensor-finney).
Example use cases
Registration cost check before joining subnet
“Before I register a miner, can you look up the current TAO burn cost and free slot count for Bittensor subnet 18 so I know if it's worth registering now?”
Monitor prune risk on target subnet
“What is the prune bar incentive for Bittensor netuid 25? I want to know how at risk a low-performing miner would be of getting pruned.”
Compare subnet saturation for slot hunting
“Check Bittensor subnet 37 — how many UIDs are filled versus the max, and what's the registration burn right now? I'm looking for an open subnet to join cheaply.”
Technical details
Endpoint
GEThttps://golf-evm-math.x402-evm-math.workers.dev/bittensor/subnet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, per-subnet registration intelligence for a specific Bittensor subnet — particularly the burn cost, slot availability, and prune risk — without querying all subnets. Prefer this over the all-subnets endpoint when you already know the netuid and want lower latency and lower cost per call.
Side effects
- Invalid or nonexistent netuid returns an error or empty response
- Network connectivity issues to Bittensor Finney may cause timeout
- Missing required netuid query parameter results in a 400-level error
- Stale data if the Bittensor chain state hasn't been recently indexed
