FREE RPC Aggregator

Public blockchain RPC pools with automatic fallback.

Use tx.taxi as a no-auth JSON-RPC proxy for supported RPC chains. Non-JSON-RPC chains are listed with their public API/indexer pools so coverage stays visible across the full registry.

Chains listed

JSON-RPC pools

Public RPC endpoints

API-only pools

Dynamic routing

Each request is sent to the best public upstream currently known for that chain. The pool tracks recent success, failure cooldown, and latency, then falls through to the next public endpoint when an upstream times out, returns HTTP errors, or sends invalid JSON.

Only endpoints marked public in the tx.taxi registry are exposed or proxied.
Registry order remains the tie-breaker for untested endpoints.
Private or API-key endpoints are filtered out before metadata and proxy calls.
Live health routes probe each chain pool independently.

Ethereum example

POST /rpc/ethereum

curl -s https://tx.taxi/rpc/ethereum \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}'

Ethereum metadata Ethereum health

92 public RPC endpoints / 26 public API endpoints

Configured public pools

JSON-RPC rows can be called through /rpc/{chainId}. API-only rows are used by tx.taxi probes and listed for coverage, but they are not POST-compatible JSON-RPC proxies.
