Technical details
Endpoint
GEThttps://dutyfinch.cybermax-tools.workers.dev/x402/api/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, single-call access to both the baseline US HTS duty rate and the China Section 301 tariff surcharge for a product, especially when searching by product keyword rather than an exact HTS code. Prefer this over manual USITC lookups or separate tariff databases when building import cost calculators, trade compliance checks, or procurement tools that need real-time tariff data without sign-up friction.
Side effects
- No matching HTS codes found for vague or misspelled product descriptions
- Partial or ambiguous code prefix returns too many or irrelevant results
- Section 301 tariff data may lag behind recent executive actions or exclusions
- Limit parameter out of range (must be 1-25) returns validation error
- Missing required query parameter 'q' may return an error or empty result
