Quickstart

Fetch the latest Sonic block number. Replace YOUR_API_KEY with a key from the dashboard. New accounts start on the Free plan, no card required (see getting started):

Request example

curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/146 \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

Archive access and tracing

There is no separate archive endpoint for Sonic. Historical queries route to archive nodes automatically by block age, at no surcharge.

The debug_* tracing namespace is available:

Request example

curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/146 \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"debug_traceTransaction","params":["0xTRANSACTION_HASH",{"tracer":"callTracer"}],"id":1}'

Parity-style trace_* methods are also available.

Limits and errors

Quotas and rate limits are account-wide, not per-chain. Method calls to Sonic draw from the same response-unit quota and rate limit as every other network. Error bodies are identical everywhere. See the error reference.
