How this service works
Checks supplied preference-origin criteria and reports the applied threshold. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age. This is neither legal advice nor customs advice.
Output
Returns the applied origin threshold for the supplied criteria, disclosing whether values are derived (with method) or source-backed (with source URL, time window, and data age). Fields that could not be determined are returned as null and listed in an unavailable_fields array. Includes a disclaimer that results are not legal or customs advice.
Example use cases
USMCA regional value content check
“I'm shipping auto parts made in Mexico to the US — can you check the origin rules under USMCA with an origin country of MX, a minimum percent of 62.5, and a qualifying value percent of 60, and tell me whether that threshold applies and how it was calculated?”
EU GSP preferential origin verification
“We're sourcing textiles from Bangladesh and want to claim EU GSP preference — look up the origin criteria under the EU GSP agreement for origin country BD with a minimum percent of 50, and let me know the applied threshold and any fields that couldn't be determined.”
Trade compliance sourcing decision
“Before we finalize our supplier in South Korea, can you check the rules of origin under the EU-Korea FTA with origin country KR, minimum origin percent of 55, and qualifying value percent of 50, so I know the threshold we need to hit for preferential duty treatment?”
Technical details
Endpoint
POSThttps://zoll.halowerk.com/v1/origin-rules?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check whether a product meets the rules-of-origin percentage thresholds under a specific trade agreement, and you want transparency about how the threshold was derived and what data sources back it. It is particularly valuable when you already have a source document (e.g. a published official rule) and want structured threshold reporting with method disclosure. Prefer this over general tariff or duty endpoints when the specific question is about origin qualification criteria rather than duty rates or document requirements.
Side effects
- Missing required source fields (url, published_at, title) cause validation errors
- Invalid ISO 3166-1 alpha-2 origin_country code returns an error or null threshold
- Percent values outside 0–100 range are rejected by schema validation
- Unknown or unsupported trade agreement in the agreement field may result in null threshold and populated unavailable_fields
- Payment failure (x402) blocks access if USDC payment is not processed
- Source URL is unreachable or unparseable, leading to null source-backed values
