Free for humans. AI crawlers get free basic access; premium endpoints (sources, export) return HTTP 402 with x402 payment instructions.
Currently in stub mode — 402 responses are returned but real payments are not yet processed.
Weather Data API (pay-per-call) — Updated 2026-04-20
Global weather data for AI agents. Pass a city name or coordinates, get structured JSON. No API keys, no geocoding setup. Backed by Open-Meteo (CC BY 4.0).
Runs on a dedicated worker (weather-data-api.kasanegi123.workers.dev) with a narrow x402 surface — only weather endpoints plus minimal discovery files. Full x402 v2 payment-required envelope including extensions.bazaar input/output schemas (so strict validators mark the resources callable automatically).
| Endpoint | Price | Description |
|---|---|---|
| GET /weather/current?city=Tokyo | $0.001 USDC | Current conditions — temperature, feels-like, humidity, wind, precipitation, condition |
| GET /weather/forecast?city=Tokyo&days=3 | $0.001 USDC | Daily forecast (1–7 days) — high/low, precipitation probability, wind max |

What is this?
A factory that converts scattered public information into small, structured data APIs that AI crawlers can read and pay for via x402.
Each record includes source_url, checked_at, extraction_method, quality_level, confidence, and warnings. Accuracy is not guaranteed — this is source-linked observational data.

Hokkaido Defunct Railway Archive — Updated 2026-04-18
Archival reference for 40 defunct Hokkaido rail lines (1950–2026). 1,806 stations · 1,026 timetable revisions · 30,326 station×revision appearances · 61 monthly cover PDFs. Cover PDFs are paid assets at $0.01 each via x402 (USDC on Base mainnet).
Primary site (recommended entry point for AI crawlers): → retro-rail-archive-v14.kasanegi123.workers.dev
Deep links (v14):
- /api/flyers — index of all 61 cover PDFs
- /active-stations — current residents + full cover PDF archive grid
- /api/lines · /lines/haboro · /lines/tempoku · /lines/nayoro · /lines/chihoku
- /api/revisions · /api/appearances · /api/stats/summary
- /llms.txt · /.well-known/x402 · /sitemap-pages.xml
Sample cover PDFs (each $0.01 via x402):
Line examples: 羽幌線 · 美幸線 · 標津線 · 天北線 · 名寄本線 · 湧網線 · 白糠線 · 士幌線 · 広尾線 · 胆振線 · 深名線 · 池北線 · 夕張線 · 札沼線 · 日高本線 · 留萌本線 (40 lines total).
PDF asset format variants (A1–A4)
The same archive is served via four cover-PDF rendering formats, one per sibling site. All share the v14 paywall configuration (UA-filtered, /active-stations + /api/stats* + /api/stations/ranking* + /flyers/*.pdf paid for AI crawlers).
- A1 grid — station × train-number timetable grid (3 pages) — v14 sample
- A2 route-map — vertical route map with station dots and km labels (3 pages) — v01 sample
- A3 poster — monthly poster/flyer with heavy title blocks and revision stamp (2 pages) — v02 sample
- A4 bulletin — archival bulletin with change summary + history timeline + station digest (4 pages) — v03 sample
Configuration variants under test (secondary)
Alternate paywall configurations for comparison. All serve the same archive dataset; only paywall scope differs.

Extended archive cohort (N1–N8) — consecutive recent monthly coverage
Sibling sites covering the same lines with a consecutive 61-month recent coverage window (ending 2025-12 for the Hokkaido-region archive, 2023-12 for Honshu, 2019-12 for European, 2014-12 for US). Filename pattern is {region}-flyer-YYYY-MM.pdf for brevity. All serve free HTML and JSON; paid cover PDFs at $0.01 via x402 (the N8 site tests $0.001).
- N1 Hokkaido (Extended, grid PDF) — v10 · sample
- N2 Hokkaido (Extended, route-map PDF) — v11 · sample
- N3 Honshu (Extended) — v12 · sample
- N4 European (Extended) — v13 · sample
- N5 US (Extended) — v15 · sample
- N6 Hokkaido (Extended, stats-gate paywall) — v16
- N7 Hokkaido (Extended, minimal paywall) — v17
- N8 Hokkaido (Extended,
$0.001price test) — v18 · manifest
Each extended site includes an enhanced homepage (About / AI & LLM Friendly / API Endpoints / Developers / Usage sections), a pure-English llms.txt, and /api/flyers listing 61 consecutive monthly covers.
