# 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.

| `classification_reasons` | array or pipe-separated string | All classes that fired for the row. |
| `first_seen_at` | ISO 8601 or null | First time x402station.io saw the endpoint. |
| `last_probe_at` | ISO 8601 or null | Most recent probe included in the aggregate window. |
| `total_probes_30d` | integer | Count of HTTP-naked probes in the trailing 30-day window. |
| `uptime_30d_pct` | number or null | Percent of 30-day probes returning HTTP 200 or 402. |
| `latency_p50_ms` | integer or null | 30-day p50 latency across probes with an HTTP status. |
| `latency_p95_ms` | integer or null | 30-day p95 latency across probes with an HTTP status. |
| `latency_p99_ms` | integer or null | 30-day p99 latency across probes with an HTTP status. |
| `price_amount_usdc` | number or null | Current public catalog price amount, normalized as USDC where supplied. |
| `price_currency` | string or null | Current public catalog currency. |
| `cdp_l30d_calls` | integer or null | Coinbase CDP Bazaar 30-day settlement count when synced. |
| `cdp_l30d_unique_payers` | integer or null | Coinbase CDP Bazaar 30-day unique payer count when synced. |
| `cdp_last_called_at` | ISO 8601 or null | Last CDP-observed settled call timestamp when synced. |
| `cdp_last_synced_at` | ISO 8601 or null | Last CDP quality sync timestamp. |
| `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.

## 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.
