sigil_quoteDexSwapExactIn
Quote an exact-input swap.
Method
sigil_quoteDexSwapExactIn is registered in the canonical JSON-RPC catalog. Use POST /rpc, Content-Type: application/json, JSON-RPC 2.0 and a caller-controlled request id. Node RPC profile, build feature and runtime activation checks still apply.
Quote an exact-input swap.
Request binding
Source handler: rpc_dex::handle_quote_dex_swap_exact_in in sigil/node/sigil-node/src/rpc_dex.rs, line 111.
The handler uses no directly named params.get fields, or delegates input parsing to a typed helper. Use the request types below rather than assuming an empty parameter object.

Check HTTP status, parse the JSON-RPC envelope, reject error, and require result on success. Preserve large base-unit integers without floating-point rounding. A catalog method does not bypass authentication, capability, policy or activation requirements.
