How this service works
Independent measurement and scoring of the Sentinel dVPN network. Pay per call in USDC over x402 — no account, no API key, no signup.
Output
Returns a JSON object with two main sections: 'node' (current metrics including composite_score, uptime, speed_dl_mbps, speed_ul_mbps, sla_pass, reliability, peers, leases, price_gb, price_hr, jurisdiction_freedom, censorship_resistance, country, city, ASN, protocol, and asn_saturated flag) and 'history' (a compact timeline string, stability score, average price position, age, transaction count, and date range). Also returns network_rank and network_active_total for context within the broader Sentinel network.
Example use cases
Vetting a dVPN node before connecting
“I'm about to route traffic through Sentinel node sentnode1abc123xyz — can you check its scorecard and tell me the composite score, download speed, uptime, and jurisdiction freedom score so I know if it's trustworthy?”
Comparing node quality for a VPN app
“I'm building a list of top Sentinel dVPN nodes. Can you grab the scorecard for sentnode1nmse5z50klakvwuy68w4wdgdvwzfasl8ryu9wk and tell me its network rank out of all active nodes, reliability rating, and price per GB?”
Monitoring SLA compliance of a node
“Check whether Sentinel node sentnode1nmse5z50klakvwuy68w4wdgdvwzfasl8ryu9wk currently passes its SLA, and give me its uptime percentage and speed stats so I can decide whether to keep it in our approved node list.”
Technical details
Endpoint
GEThttps://nodescorecard.xyz/scorecard/node/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need independent, third-party quality measurements of a specific Sentinel dVPN node — especially composite scoring, SLA compliance, speed benchmarks, and jurisdiction/censorship data. Prefer it over self-reported node metrics or raw Sentinel RPC queries when you need a normalized, comparable score across the network. Ideal for node selection logic in VPN clients, node directory curation, or compliance checks.
Side effects
- Invalid or malformed Sentinel node address returns an error or empty result
- Node address not found in the network returns a 404 or empty node object
- Node has no recent samples, resulting in stale or incomplete scoring data
- Upstream Sentinel network data unavailable causes degraded or missing metrics
- Payment of $0.003 USDC via x402 fails if wallet is underfunded or x402 protocol handshake fails
