seo_intro: |
Canto is a permissionless EVM L1 (chain 7700) built around free public infrastructure; its DEX, lending market, and stablecoin are protocol primitives rather than third-party dApps. The official endpoint (`canto.gravitychain.io`) is maintained by Plex, with dRPC, PublicNode, and Ankr providing additional keyless alternatives probed every 60 seconds from three regions.

abstract: |
Per-chain member of the RPC latency cluster, extended to Canto.
We measure the round-trip latency of a single, identical RPC call
(`eth_getBlockByNumber`) against every no-key public Canto endpoint
that sustains continuous probing, 4 providers at launch,
every 60 seconds, from us-east, eu-west and Singapore. The harness
classifies every response (ok / http_err / jsonrpc_err / stale /
timeout) so the leaderboard rewards sustained availability rather than
fast error messages. The cross-chain view lives on the parent
`rpc-capabilities` benchmark; this page is the Canto-scoped answer
with per-region breakdowns as a first-class dimension.
(`eth_getBlockByNumber`) against the no-key public Canto endpoint
(Canto Official, canto.gravitychain.io), every 60 seconds, from
us-east, eu-west and Singapore. The harness classifies every response
(ok / http_err / jsonrpc_err / stale / timeout) so the leaderboard
rewards sustained availability rather than fast error messages.
The cross-chain view lives on the parent `rpc-capabilities` benchmark;
this page is the Canto-scoped answer with per-region breakdowns
as a first-class dimension.

methodology:
- "Cadence: every 60 seconds per provider, from each of 3 probe regions (us-east Virginia, eu-west Amsterdam, sgp Singapore). Headline p50/p90/p99 aggregate across all 3 regions via Prometheus `avg(quantile_over_time(...))`; per-region breakdowns are first-class on this page via the region tabs."
- "Payload: `{\"jsonrpc\":\"2.0\",\"id\":<rotating>,\"method\":\"eth_getBlockByNumber\",\"params\":[\"latest\",false]}`. Plain HTTP POST, identical for every endpoint, no API key in any request."
- "Latency: client-side round-trip delta in milliseconds, exposed as both a gauge and a histogram (buckets 50 ms → 10 s), so percentiles are computed via Prometheus `quantile_over_time` over the last 24 hours."
- "Call-result classification: `ok` (HTTP 200 + non-empty result), `http_err`, `jsonrpc_err` (HTTP 200 carrying an error body), `stale` (more than 20 blocks behind the cross-provider tip), `timeout`."
- "This page is part of the per-chain RPC cluster derived from the cross-chain [rpc-capabilities](https://openchainbench.com/benchmarks/rpc-capabilities) benchmark; the identical harness, cadence and exclusion rules apply on every chain."
- "Chain scope: every query on this page is pinned to `chain=\"canto\"`. Provider coverage at launch: 4 no-key endpoints (Canto Official, dRPC, PublicNode, Ankr)."
- "Chain scope: every query on this page is pinned to `chain=\"canto\"`. Provider coverage: 1 no-key endpoint (Canto Official). dRPC requires an API key; Ankr and PublicNode dropped free Canto support."

findings:
- "{{best_name}} currently leads free Canto RPC at {{best_p50}} (`eth_getBlockByNumber` p50, 24h) across 4 measured providers."
- "{{best_name}} currently leads free Canto RPC at {{best_p50}} (`eth_getBlockByNumber` p50, 24h)."

faq:
- q: "What is the fastest free Canto RPC right now?"
a: "{{best_name}} currently leads at {{best_p50}} (`eth_getBlockByNumber` p50 over the last 24h), measured against 4 no-key providers probed every 60 seconds from us-east, eu-west and Singapore. The leaderboard re-sorts continuously against fresh Prometheus samples."

- q: "Which Canto RPCs work without an API key?"
a: "4 endpoints sustain continuous keyless probing at launch: Canto Official, dRPC, PublicNode, Ankr. Every listed endpoint was live-verified before inclusion."
- q: "Does the fastest Canto RPC change by region?"
a: "Often. The region tabs at the top of the page re-scope every number to a single origin; pick the one closest to where your requests originate."
a: "The Canto Official endpoint (`canto.gravitychain.io`, operated by Plex) is the only keyless endpoint sustaining probes from all 3 regions. dRPC requires an API key; Ankr and PublicNode have dropped free Canto support."
- q: "Does the Canto RPC latency change by region?"
a: "Yes. The region tabs at the top of the page re-scope every number to a single origin; pick the one closest to where your requests originate."
- q: "How is Canto RPC latency measured here?"
a: "One identical JSON-RPC POST (`eth_getBlockByNumber`) every 60 seconds against each provider from each of 3 regions. Responses are classified so an endpoint stuck on an old head or returning errors is never ranked as fastest."
