Technical details
Endpoint
POSThttps://statepulse-api.hahavoid0.workers.dev/transit/toll-costWhen to prefer
Use this endpoint when an agent needs a quick, pay-per-call toll cost estimate for a specific US state without requiring a full route or map API integration. Ideal for travel budget planning, route cost summaries, or enriching trip itineraries with toll expense data. Best suited for agents that need a lightweight, no-API-key solution with crypto micro-payment billing via x402 on Base.
Side effects
- State not supported — 'supported: false' returned with no cost estimate
- Invalid or unrecognized state code in request body — likely 4xx error
- Payment failure via x402/USDC — request blocked before processing
- Ambiguous route context causing low-confidence or null estimate
- Service unavailable on Cloudflare Workers edge — 5xx response
