x402station.io Preflight Dataset v0.1

x402station.io Preflight Dataset v0.1 — aggregated probe data from the x402 agentic-commerce network.

This dataset is a weekly public snapshot of endpoint-level aggregate health and risk signals used by Preflight by x402station.io. It is designed for citation, reproducibility, ecosystem analysis, and lightweight agent-routing research without exposing the raw probe-by-probe time-series that powers the paid API.

Probe Methodology

x402station.io probes every indexed x402 endpoint on an approximately 10-minute cadence. A probe is an HTTP naked call: no PAYMENT-SIGNATURE, no paid settlement, and no attempt to consume protected paid content. The probe records aggregate availability evidence such as status class, network failure, and latency.

This public dataset contains endpoint-level aggregates only. It intentionally does not include raw probe-by-probe rows, raw response bodies, payment signatures, wallet identifiers, webhook payloads, or per-request time-series.

Classification Heuristics

The public classes mirror the x402station.io signal vocabulary documented at https://x402station.io/spec#signals.

Class	Heuristic
live	No v0.1 dataset class fired. Check total_probes_30d and last_probe_at before treating this as a guarantee.
decoy_price_extreme	Current price is at least $1,000 USDC.
zombie	At least 3 probes in the last hour and zero healthy responses.
dead	At least 3 unhealthy probes in the last 30 minutes.
dead_7d	At least 20 probes in 7 days and zero healthy responses.
mostly_dead	At least 20 probes in 7 days and uptime below 50%.
never_paid_zombie	CDP synced, zero 30-day settled calls, no historical last-called timestamp, endpoint older than 30 days.
new_provider	Service first seen less than 24 hours before export.
slow	Last-hour average latency at least 2,000 ms, or 30-day p99 latency at least 5,000 ms.
price_outlier_high	Current price is at least 10x the provider/domain group median.
high_concentration	Provider/domain group accounts for at least 5% of active catalog endpoints.

When multiple classes fire, classification is the highest-priority class and classification_reasons lists the complete set.

Refresh Cadence

The intended public cadence is weekly snapshot refresh. The paid Preflight API remains the fresh path for production agents that need current verdicts, batch checks, and SLA behavior.

Boundary Policy

Open: endpoint-level aggregate stats, public catalog metadata, classification labels, settlement count/recency aggregates when synced from CDP Bazaar.

Gated: raw probe-by-probe time-series, per-probe response detail, paid API freshness, bulk routing checks, webhook monitoring, and SLA surfaces.
