x402
Invoket Chemical Substance Batch Classification is a paid API for AI agents from api.invoket.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Batch-classifies chemical substances by CAS number, EC number, or name against regulatory/hazard labels as of a specified date, returning provenance-backed results for each item.

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
An object containing per-item classification results for each substance submitted, including regulatory/hazard label, provenance information sourced from official databases, and any per-item INVALID_INPUT errors for malformed identifiers — without failing the rest of the batch.
Example use cases
Bill of materials compliance screening
“I have a list of 50 substances from our product BOM with their CAS numbers — can you classify all of them for regulatory hazard labels as of today and flag any that are restricted?”
Chemical name hazard lookup
“We have chemical names like 'benzene', 'acetone', and 'formaldehyde' — can you batch classify them to see their official hazard or regulatory status as of 2025-01-01?”
EC number regulatory verification
“Before we finalize our supplier order, can you check these EC numbers — 200-753-7, 231-791-2, and 203-625-9 — against the current classification lists to confirm none are restricted substances?”
Technical details
Endpoint
POSThttps://api.invoket.com/label/chem/classify/batchWhen to prefer
Choose this endpoint when you need to classify multiple chemical substances in a single API call, especially when working with bills of materials or supplier lists. It is ideal when you need point-in-time regulatory classification (specifying a date) with official provenance. Prefer it over single-item lookups when screening more than one substance to reduce cost and round-trips. Best suited for compliance workflows, pre-procurement checks, and EHS screening pipelines.
Side effects
- Batch exceeds 200 items → 400 error
- Empty batch submitted → 400 error
- Malformed CAS or EC checksum → INVALID_INPUT at that position, rest of batch continues
- Unknown substance identifier → no match result for that item
- Invalid date format for 'at' field → validation error
- Multiple keys provided per item (e.g. both cas and name) → validation error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| atrequired | string | Optional date (YYYY-MM-DD, default today) the whole batch is evaluated at - a BOM is assessed at a single date |
| 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 |
