WHAT IT DOES

What get_stake_action_preview does on metagraphed — Bittensor subnet operational registry

AI agents call get_stake_action_preview 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.

Parameter	Type	Required	Description
`amount`	number	Yes	Amount to quote, in TAO when staking and in alpha when unstaking. Must be greater than 0.
`netuid`	integer	Yes	Subnet id (netuid), 0-65535. 0 is the root subnet, which is special: it has no AMM pool and is emission-ineligible.
`context`	string	—	Optional: the user's goal, briefly. Analytics only; does not affect the result.
`direction`	string	—	Restrict the result to this kind. Options are per-tool; see this parameter's enum.

Parameters from the server's own tool schema.

FAQ

Questions about get_stake_action_preview

What does the get_stake_action_preview tool do? +

Produce a clearly-labeled, human-readable PREVIEW of what a hypothetical stake or unstake against one subnet would look like: the estimated resulting amount out, the effective vs spot price, and the estimated price-impact/slippage -- computed from the same live AMM pool economics get_subnet_stake_quote reads (direction stake spends amount TAO for alpha; unstake spends amount alpha for TAO; root netuid 0 is 1:1). This is INFORMATIONAL ONLY and strictly READ-ONLY: it does NOT execute, build, prepare, or sign any transaction, produces no signable/extrinsic artifact, and never touches a wallet or key. Submitting a stake requires a separate signed extrinsic outside this tool. Use it to explain a prospective stake's outcome to a user, not to act on-chain.
