How this service works
Pay-per-call logistics, shipping, trade and energy data tools for AI agents, from official and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.
Output
A JSON object containing: the number of matching paragraphs found (count), the eCFR source URL, the keyword used, the timestamp of the check, and an array of matching paragraph text strings from 49 CFR 173.185. Each paragraph is a verbatim excerpt from the official US federal regulation.
Example use cases
Air freight lithium battery compliance check
“What does 49 CFR 173.185 say about transporting lithium batteries on passenger aircraft? Search the US federal reg text for the keyword 'passenger aircraft' and give me up to 5 paragraphs.”
UN number rule lookup for dangerous goods
“Find all the paragraphs in 49 CFR 173.185 that mention 'UN3480' — I'm preparing a dangerous goods declaration and need to confirm what the US DOT rules say specifically about that UN number.”
State of charge requirement research
“Search the US lithium battery hazmat regulation 49 CFR 173.185 for mentions of 'state of charge' and return up to 4 paragraphs — I need to check if there's a charge limit required before shipping.”
Technical details
Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/logistics/lithium-battery-rules?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly find the specific text of US federal regulation 49 CFR 173.185 governing lithium battery transport without purchasing the IATA Dangerous Goods Regulations. Prefer this over general web search when you need verbatim official US DOT/PHMSA rule text for compliance research, dangerous goods documentation, or legal referencing. This is not a substitute for legal advice and does not cover IATA DGR (which requires a paid publication) or non-US regulations.
Side effects
- Keyword too short (under 3 characters) or too long (over 40 characters) returns validation error
- No matching paragraphs found returns count of 0 and empty array
- eCFR upstream API unavailable causes fetch failure
- Limit parameter outside 1–10 range may be rejected or clamped
- Stale regulation text if eCFR source has not been updated recently
