ParameterTypeRequiredDescription
limit integer Maximum rows to return (1-1000). Defaults to 100 when omitted. The response reports the limit actually applied.
cursor string Opaque pagination token: pass back the `next_cursor` from the previous response verbatim. Its contents are not stable and must not be parsed or constructed. Sta
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.
offset integer Rows to skip before the first returned row (0-1000000). Defaults to 0; a non-numeric value resolves to 0 and the response reports it.
context string Optional: the user's goal, briefly. Analytics only; does not affect the result.
