+# 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.

+| `has_free_trial` | boolean or null | Whether CDP enrichment reports a free trial path. |
+| `generated_at` | ISO 8601 | Snapshot generation timestamp. |
+
+## 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](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.

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