Songbird RPC endpoints: free public URLs by latency
HTTP round-trip latency for eth_getBlockByNumber against every free, no-key public Songbird EVM endpoint, audited every 60 seconds from 3 regions.
TL;DR. As of , Flare Foundation is the only free public Songbird RPC endpoint measured, at 145 ms (p50, 24h, 3 regions). Source: OpenChainBench, https://openchainbench.com/benchmarks/songbird-rpc.

Songbird (chain 19, SGB) is Flare Network's canary network, a production EVM-compatible chain used to test and validate Flare's FTSO oracle system before mainnet deployment. One keyless endpoint is probed continuously: the official Songbird gateway (songbird-api.flare.network/ext/C/rpc). The FTSO AU community node (songbird.rpc.ftso.au) was removed after DNS went dead.
Methodology
Songbird: 1 free public RPC endpoints answering `eth_getBlockByNumber` every 60 seconds from us-east, eu-west and Singapore, ranked by 24h median. Flare Foundation leads at 145 ms; the chain-official endpoint measures 145 ms. We measure the round-trip latency of a single, identical RPC call (`eth_getBlockByNumber`) against the no-key public Songbird endpoint that sustains continuous probing (1 provider: Flare Foundation official), every 60 seconds, from us-east, eu-west and Singapore. The cross-chain view lives on the parent `rpc-capabilities` benchmark; this page is the Songbird-scoped answer with per-region breakdowns as a first-class dimension.

Frequently asked
Which Songbird RPCs work without an API key?
1 endpoint sustains continuous keyless probing: Flare Foundation official (songbird-api.flare.network/ext/C/rpc). The FTSO AU community node was removed after its DNS went dead.
