debug_traceCall trace a read-only EVM call. The published signature and response shape come from the measured Robinhood OpenRPC contract.

Parameters

JSON-RPC params is a positional array.

callCallrequired

Positional OpenRPC parameter.

blockBlockTagrequired

Positional OpenRPC parameter.

optionsTraceOptionsrequired

Positional OpenRPC parameter.

Response

Representative envelope with the top-level shape of the accepted fixture:

Errors

See Robinhood errors. Invalid parameters return a JSON-RPC parameter error; authentication and quota failures use the shared client error contract. Unknown failures are returned without an implicit retry.

Examples

JavaScript

const response = await fetch("https://triport.io/rpc/robinhood", {
  method: "POST",
  headers: { "x-token": process.env.TRIPORT_API_KEY, "Content-Type": "application/json" },
  body: JSON.stringify({"jsonrpc":"2.0","id":1,"method":"debug_traceCall","params":[{"to":"0x0000000000000000000000000000000000000000","data":"0x"},"latest",{"tracer":"callTracer"}]}),
});
const payload = await response.json();

Notes

This is best-effort through one measured operator. Availability has no SLA.
Parity-style trace_* methods are not in the Robinhood catalog.
