Why ALETHEIA

Chemical safety API comparison — what changes when regulatory data is an API call away

One API Call vs Hours of Manual Research

Manual Research

  • Search CAS number on PubChem
  • Cross-reference with EPA CompTox
  • Check EU ECHA registration dossiers
  • Look up California Prop 65 list
  • Read FDA guidance documents
  • Reconcile conflicting classifications

2-4 hours per compound

ALETHEIA API

  • One GET request
  • Synthesized risk data from 202 agencies
  • 19 exposure contexts included
  • Statistical consensus detection
  • Source weights disclosed
  • JSON response, ready to use

<200ms, 1 API credit

Coverage That Compounds

One API, one schema, one query pattern across the full chemical safety landscape:

What Count
Compounds 1,879 (organic, inorganic, mixtures)
Materials 959 (structural, surface, chemical, environmental, advanced)
Products 1,262 (8 consumer categories)
Exposure contexts 19 (human_adult, human_infant, dermal, oral, environmental...)
Regulatory agencies 202
Fragrance ingredients 2,325

Multi-Context Risk Synthesis

When agencies disagree, that disagreement is data

Other sources pick one agency and call it the answer. ALETHEIA shows the full distribution: mean, standard deviation, confidence interval, consensus strength. You see the shape of the evidence, not a collapsed point.

19 exposure contexts mean the same compound gets different risk profiles depending on who is exposed and how. Formaldehyde at workplace inhalation levels is a different question than formaldehyde in a baby shampoo at 0.1% concentration.

An adult dermal exposure, an infant oral exposure, and an aquatic environmental release are three fundamentally different risk scenarios. ALETHEIA models all of them from the same compound record.

No other chemical safety API provides context-dependent risk synthesis.

Real-Time Data, Not Static PDFs

Downloaded PDFs and spreadsheets go stale the moment you save them. ALETHEIA stays current:

Regulatory landscapes shift constantly. IARC reclassifies compounds. EPA updates IRIS assessments. EFSA revises ADIs. Your data layer should reflect that — automatically.
