## Services

- [ChemEq Limiting Reagent Calculator](https://www.zero.xyz/c/chemeq-limiting-reagent-calculator-5c6b056f/llms.txt): $0.004/call via x402. Given a chemical reaction equation and supplied amounts of all reactants, identifies the limiting reagent and computes leftover amounts of excess reactants plus theoretical product yields.
- [ChemEq Stoichiometry Calculator](https://www.zero.xyz/c/chemeq-stoichiometry-calculator-76cf2615/llms.txt): $0.004/call via x402. Given a chemical reaction equation and a known amount of one species, computes the amount of a target species using auto-balanced stoichiometry.
- [ChemEq Balance Equation](https://www.zero.xyz/c/chemeq-balance-equation-e308a432/llms.txt): $0.004/call via x402. Balances a chemical equation (e.g. 'H2 + O2 -> H2O') into the smallest whole-number coefficients using exact rational linear algebra.

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