How this service works
The checks your agent runs before it acts: verify a bank account, a phone number, a law in force, the weather or a vehicle — computed from official sources, with provenance in every response. You only pay for answers.
Output
A per-item array of results indicating whether each queried substance (by CAS, EC number, or name) appears on the SVHC candidate list, along with its classification details and provenance information tracing back to official sources. Items with malformed identifiers return an INVALID_INPUT error at their position without failing the entire batch.
Example use cases
Pre-shipment REACH compliance check
“Before we ship this batch to Germany, screen all 15 chemicals in our formulation against the SVHC list — I'll give you their CAS numbers. Flag anything that's a substance of very high concern.”
Product formulation safety review
“We're reformulating our adhesive product. Can you check these EC numbers — 200-193-3, 231-198-9, and 204-617-8 — to see if any of them are SVHC candidates under REACH?”
Supplier material screening
“Our supplier sent us a list of 20 raw material names. Can you run them all through the SVHC candidate list at once and tell me which ones have regulatory concerns?”
Technical details
Endpoint
POSThttps://api.invoket.com/label/chem/svhc/batchWhen to prefer
Use this endpoint when you need to screen multiple chemicals at once against the EU SVHC candidate list as part of REACH compliance workflows, product safety reviews, or supply chain due diligence. It is ideal for batch operations (up to 200 substances per call) where you have CAS numbers, EC numbers, or substance names and need provenance-backed regulatory status. Prefer this over single-substance lookups when processing entire formulations or supplier lists in one settlement.
Side effects
- Empty batch array returns 400 error
- Batch exceeding 200 items returns 400 error
- Malformed CAS or EC checksum returns INVALID_INPUT at that position (partial failure, rest of batch succeeds)
- Unrecognized substance name may return a not-found or low-confidence result
- Payment failure or insufficient USDC balance blocks the request
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| itemsrequired | array | Array of substance keys screened in one settlement. Its length is priced per unit (base + N x unit), capped at 200; an empty or oversized batch = 400. Each item takes exactly ONE key among cas, ec, name (checksum-validated for cas/ec); a malformed item yields an INVALID_INPUT error at its position without failing the batch |
