# Saylor Innovations Chemistry — Chemical Compound Lookup

> Saylor Innovations Chemistry — Chemical Compound Lookup is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Looks up chemical compound data from PubChem by name or identifier, returning properties, hazards, molecular formula, and standard identifiers

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-chemistry-chemical-compound-lookup-b66e1f83
```

Example prompt: Look up the chemical properties of caffeine — I need its molecular formula, molecular weight, PubChem CID, and any hazard information.

## When to prefer this

Use this endpoint when you need structured chemical compound data (formula, weight, CID, hazards) for a named compound without setting up direct PubChem API access. Ideal for agents needing quick, pay-per-use chemistry lookups with x402 micropayment support, especially when the compound is a well-known drug, industrial chemical, or common molecule indexed in PubChem.

## Known failure modes

- Compound name not recognized or misspelled — returns found: false with no additional data
- Ambiguous compound name matching multiple PubChem entries may return unexpected results
- Network or upstream PubChem API unavailability causing timeout or error
- Compounds with no hazard data in PubChem return an empty hazards object
- Very new or obscure compounds may not be indexed in PubChem

## How this service works

Chemical Compound Lookup (PubChem): properties, hazards, identifiers. Chemical compound lookup in PubChem by name, CAS number, CID, SMILES or InChIKey: formula, molecular weight, IUPAC name, identifiers, computed properties (XLogP, TPSA, H-bond donors/acceptors), GHS hazard signal, pictograms and H-statements, synonyms, description and structure image.

## Output

Returns a JSON object with a 'found' boolean, the PubChem CID (numeric), molecular formula string, molecular weight (number or null), and a hazards object containing safety classification data for the queried compound.
