Quickstart
Fetch the latest Linea 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):
curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/59144 \
-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 Linea. Historical queries route to archive nodes automatically by block age, at no surcharge.
The debug_* tracing namespace is available:
curl https://rpc.solidrpc.io/YOUR_API_KEY/evm/59144 \
-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 not available on this chain. Use debug_traceTransaction and debug_traceBlockByNumber instead.

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