Bittensor Subnet Info API
x402
Bittensor Subnet Info API is a paid API for AI agents from dominion-data.x402-evm-math.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).
Returns current Bittensor subnet metadata including UID count, burn TAO, max UIDs, and prune bar incentive for a given subnet on the Bittensor Finney network.

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
A JSON object containing subnet metadata: the netuid, number of active UIDs, max UIDs allowed, burn TAO cost for registration, and the prune bar incentive threshold — all scoped to the Bittensor Finney mainnet.
Example use cases
Check subnet registration cost
“What is the current burn TAO required to register on Bittensor subnet 1 right now?”
Monitor subnet capacity utilization
“How many UIDs are currently active versus the maximum allowed on Bittensor Finney subnet 1? I want to see if it's near capacity.”
Evaluate subnet incentive structure
“Can you look up the prune bar incentive and other parameters for Bittensor netuid 1 so I can decide whether to register a miner there?”
Technical details
Endpoint
GEThttps://dominion-data.x402-evm-math.workers.dev/bittensor/subnet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live Bittensor subnet parameters such as burn cost, UID slot availability, or prune bar incentive for the Finney mainnet. Prefer this over scraping the Bittensor website or using Taostats when you need machine-readable subnet data in an agent workflow and are willing to pay micro-fees per call via x402/USDC on Base.
Side effects
- Invalid or non-existent netuid returns an error or empty response
- Payment failure (insufficient USDC balance on Base) results in 402 response blocking the call
- Network timeout if Bittensor Finney node is unreachable
- Rate limiting if too many requests are made without payment
