STEM
Multi-domain computation service. Ask questions spanning chemistry (molecular properties, structure rendering), physics (constants, unit conversion), and math (symbolic integration, differentiation, equation solving, matrix operations, limits, series).
What is STEM?
Multi-domain STEM computation behind x402 micropayments. A single POST /stem/ask endpoint takes a natural-language question spanning chemistry, physics, and math. DeepSeek routes it to deterministic tools from a strict toolkit (RDKit for molecular properties/rendering, SymPy for symbolic math, Pint for dimensional analysis, scipy, CODATA physical constants) and returns a computed, verifiable answer with the list of tools used. The full deterministic tool set (JSON schemas) is exposed free at GET /stem/tools; a free /stem/diag reports service health.
Pay per call in USDC, EURC across Base, Arbitrum, Polygon, Avalanche, Ethereum, Robinhood and Arc via the x402 micropayment protocol — no subscriptions, no API keys, no wallets to configure for the caller.
