# #782 free RPC endpoints (10 Oct)
Measured sustained (eth_blockNumber, 60 req, 2 threads / 5 threads):
- drpc_public (in pool): 150 req/s burst, getLogs<=10k blocks
- public robinhood node (in pool): ~18 req/s then 429
- relay via picker-box (in pool, VPC only)
- solidrpc https://rpc.solidrpc.io/public/evm/4663: ~3.5 req/s at 2 threads, 429 at 5; getLogs <=5000 blocks; archive state ok
- nodeflare https://rpc.nodeflare.app/robinhood/public: ~1.5 req/s, 429 at 5 threads (useless)
- hypersync: needs key (401). orbitflare(10rps)/quicknode/chainstack need account signup = Ben.
Finding: no other keyless free endpoint exists; free throughput cannot double at $0 without signups. Only solidrpc adds ~3 req/s as last-resort fallback.
Proposed edit (blocked for me by permission check): /opt/common/rpcpool.py _eps(), before the `if alch:` line add
  out.append(("solidrpc", "https://rpc.solidrpc.io/public/evm/4663"))
Safe for live: live uses its own paid path; this only appends a last fallback; 429 cooldown (15s) already handled.
