# get_subnet_validator_economics Answer what it costs to become a validator on one subnet and whether a permit there actually earns. Returns the permit floor (the stake needed to hold a validator permit) and the earning floor (where the smallest validator actually earning dividends sits) -- these differ by a median of ~7x, so a permit is NOT income. Also returns the TAO cost to reach each floor priced against the subnet's live AMM pool reserves plus the registration burn, how many validator slots are open, the commission (take) validators charge here and its full distribution, whether the emission gate is open, and the live StakeThreshold/TaoWeight the floors were computed against. Use it for 'how many validators does subnet N have', 'what is the validator floor', 'what does it cost to become a validator', 'is there room in the validator set', 'what commission do validators charge'. Note that permitted, active and earning are three DIFFERENT counts and all three are returned -- asking 'how many validators' has three defensible answers. Root stake counts toward the threshold on every subnet at once, so root_tao_to_clear_threshold is the cross-subnet alternative to the per-subnet alpha costs. Read-only.

From the tool's own definition: "Answer what it costs, Returns the permit floor, the earning floor, TAO cost, validator slots, commission, emission gate, live" Risk signals: Bulk/mass operation — affects multiple targets · Admin/system-level operation ## Use case AI agents call get_subnet_validator_economics to retrieve information from metagraphed — Bittensor subnet operational registry without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
