What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of singitai.app controls every word below.

Key spending limits

get_limits, get_allowance and get_receipts read key limits, what is left before a call and spend. On Solana, SingIt's server checks the daily and per-purchase limits; the chain only caps the total delegated. Caps apply only to calls with that key to SingIt MCP and its /v1 endpoint; they do not limit spending elsewhere or protect an agent’s own wallet.
