# Chemistry Reaction Conservation Checker

> Chemistry Reaction Conservation Checker is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.037001/call, status unknown (last checked 2026-10-21).

Validates atom and charge balance in supplied chemical reaction declarations for quality control purposes.

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 chemistry-reaction-conservation-checker-865b1c1b -d '<json body>'
```

Example prompt: Can you check whether this chemical reaction is properly balanced in terms of atoms and charge? Here are my reactants and products as a list — it's public data and I need to know if the conservation laws hold.

## When to prefer this

Choose this endpoint when you need automated, programmatic quality control on chemical reaction records to verify atom and charge conservation — particularly for database ingestion pipelines, lab data auditing, or cheminformatics workflows. It is not a synthesis planner, safety checker, or feasibility predictor; use it purely for stoichiometric and charge balance validation.

## Known failure modes

- Missing required fields (reactants, products, dataClass) returns validation error
- Reactant or product arrays exceeding 16 items rejected
- Invalid dataClass enum value (must be 'public' or 'synthetic') returns error
- Malformed species data in reactant/product arrays causes parse failure
- Payment not provided or insufficient USDC causes x402 payment required response

## How this service works

Check supplied reaction declarations for atom and charge accounting. For record quality control; no reaction feasibility, synthesis procedure or safety claim.

## Output

Returns a structured result object containing atom and charge conservation findings, a list of boundaries (flagged issues or violations), an input digest, a receipt digest, the offer ID, version, and the amount charged in base units. Does not assess reaction feasibility, safety, or synthesis routes — only mass and charge balance.
