How this service works
One substance, with the cross-axis derivation: what every other jurisdiction (JP, EU, US, Codex, IARC, JECFA, EFSA) says about it, with per-cell sources, kept separate from what was derived
Output
A structured object with one entry per jurisdiction (JP, EU, US, Codex, IARC, JECFA, EFSA) describing the regulatory status of the substance in that jurisdiction, each cell annotated with its source(s). A separate 'derived' section flags any status, coverage, or confidence values that were inferred rather than directly sourced. If nothing can be concluded, the API returns a refusal rather than an empty or misleading result.
Example use cases
Regulatory clearance check for product launch
“We're launching a product with citric acid in both the EU and Japan — pull up the cross-jurisdiction regulatory diff for eu:e330 so I can see what each authority says and where there are any gaps or derived conclusions.”
Fact-checking a food safety claim
“Someone told me aspartame is banned in the US but approved in the EU — can you pull the Additive Atlas diff for jp:designated-aspartame and show me what the US, EU, JECFA, and EFSA each officially say, with sources?”
Ingredient audit for an imported product
“I need to audit whether the preservative with ID us:cfr-184-1033 is consistently approved across all the major food safety jurisdictions — show me the full cross-axis diff including which conclusions were derived versus directly cited.”
Technical details
Endpoint
GEThttps://api.additiveatlas.monon.space/v1/substances/:id/diff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single-substance, multi-jurisdiction regulatory comparison with explicit sourcing and a clear distinction between primary and derived data. It is preferable over general web search when you need structured, per-cell sourced regulatory data in a machine-readable format across JP, EU, US, Codex, IARC, JECFA, and EFSA simultaneously.
Side effects
- Unknown substance ID returns an error or refusal — IDs must be obtained from the free /v1/substances search endpoint first
- If cross-jurisdiction data is too sparse or ambiguous, the API returns a refusal rather than a low-confidence guess
- Derived conclusions may be incorrect — the response flags confidence and coverage to indicate reliability
- Network or payment (x402) failures may result in no response; caller must handle 402 Payment Required
