How this service works
Real-time Tokyo train delays, line disruptions, route planning and delay-aware alternative routes (ODPT data). Pay per call with USDC via x402 — no API key.
Output
A JSON object containing the primary route's delay status and travel duration in minutes, followed by a ranked list of alternative routes each with their own delay status, duration, and rank number — allowing the agent to compare on-time probability and travel time across options.
Example use cases
Morning commute disruption workaround
“My train from 池袋 (Ikebukuro) to 東京 (Tokyo) station is delayed this morning — can you find me the top 2 alternative routes that are currently running normally?”
Meeting arrival time planning
“I need to get from 新宿 (Shinjuku) to 品川 (Shinagawa) by 14:00 today — can you check if the primary route is delayed and suggest alternatives so I'm not late?”
Real-time disruption comparison for tourists
“We're trying to get from 浅草 (Asakusa) to 原宿 (Harajuku) — are there any delays on the main route and what's the quickest unaffected alternative right now?”
Technical details
Endpoint
POSThttps://transit.agentic-jp.com/alternative-routesWhen to prefer
Choose this endpoint when you need real-time, delay-aware route comparison for Tokyo train travel specifically, and want pay-per-call access without API key registration. It is ideal for agents handling live commute disruptions or time-sensitive navigation in the Tokyo rail network. Prefer it over generic mapping APIs when ODPT-sourced accuracy and alternative ranking by delay status matter.
Side effects
- Missing required 'from' or 'to' fields returns a validation error
- Station names not in Japanese characters may fail to resolve to ODPT station identifiers
- Payment failure or insufficient USDC balance blocks the request via x402 protocol
- Stale or unavailable ODPT feed may return outdated delay information
- No alternatives found if only one viable route exists between stations
