How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a list of matching HTS entries, each with the full HTS number, tariff description, general duty rate (e.g. 'Free' or percentage), other duty rate (e.g. '30%'), and units of measure (e.g. 'No.'). The response is JSON with a 'query' echo and a 'results' array.
Example use cases
Import duty check for electronics
“What is the general duty rate and tariff description for HTS code 8517.12 — I'm importing wireless handsets and need to know the exact customs rate.”
Trade compliance classification audit
“Can you pull the US HTS tariff details for code 8456.11.70.00? I need the general rate, other rates, and units for our import documentation.”
Supply chain cost estimation
“Look up the US tariff schedule entry for HTS code 9403 — I need the duty rate and description so I can estimate landed costs for furniture imports.”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/hts-tariff-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, per-call HTS tariff lookups without signing up for an account or obtaining API keys — ideal for AI agents performing trade compliance checks, import cost estimation, or customs classification in automated workflows. Prefer this over full CBP or USITC APIs when low-latency, pay-per-use access via USDC micropayments (x402) is acceptable and you only need duty rates and descriptions for specific HTS codes.
Side effects
- Invalid or non-existent HTS code returns empty results array
- Malformed query string may return no matches
- Payment failure (x402) if insufficient USDC balance on Base
- Rate-limiting or server unavailability from dynamic DNS host
- Query too ambiguous may return multiple unrelated HTS entries
