sigil_getMacaEpoch
Fetch a MACA epoch by ID.
Method
sigil_getMacaEpoch 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.
Fetch a MACA epoch by ID.
Request binding
Source handler: rpc_compute::handle_get_maca_epoch in sigil/node/sigil-node/src/rpc_compute.rs, line 576.
The handler directly reads these named fields: epoch_id. Additional typed parsing, aliases and nested validation are defined by its request types. Field presence alone does not establish optionality.
Parsing excerpt
These source excerpts show binding and validation; they are not runnable client code.
let epoch_id = match req.params.get("epoch_id").and_then(Value::as_u64) {
Some(v) => v,
None => {
return RpcResponse::error(req.id.clone(), -32602, "missing 'epoch_id' parameter");Responses and failures
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.
