Concurrent-failover Base JSON-RPC gateway — public good + paid quota via x402 (USDC on Base). Updated 2026-09-05T04:30:02Z

Live public Base RPC health

Every request to /rpc fans out to all upstreams in parallel — first healthy response wins. This board is the same probe the gateway trusts.

Upstream	Status	Latency	7d uptime
`https://mainnet.base.org`	UP	212 ms	100.0% (13 samples)
`https://base.llamarpc.com`	DOWN	88 ms	0.0% (13 samples)
`https://base-rpc.publicnode.com`	UP	56 ms	100.0% (13 samples)
`https://1rpc.io/base`	DOWN	114 ms	0.0% (13 samples)
`https://base.drpc.org`	UP	34 ms	100.0% (13 samples)

Free tier: 10 req/min IP — no key, no account, no cookies. Just call https://basebalance.cloud/rpc with standard JSON-RPC.

Paid: $0.50 USDC → 10,000 requests (or 24h, whichever first)
1. Send 0.50 USDC to 0xe51e284b6Fbd870F43A2B112d40e48b34F8a7963 on Base (chain 8453).
2. Retry your RPC call with header x-paywall-tx: <txhash>.
3. Done. Quota is per-IP in memory; every payment is public in the ledger and every response carries quota headers (x-quota-*).

Failure history documented, not hidden: incident postmortems. This gateway never charges for data freely available elsewhere — the free tier keeps that honest.
