x402 APIPassing, checked 3 h ago

Deterministic, paid-per-render SVG bar chart generator for LLM agents. Accepts labeled scalar data and layout options, performs exact geometry math (min/max normalization, nice-interval y-axis ticks, label spacing, bar-width distribution), and returns schema-valid, escape-correct SVG with identical input always yielding byte-identical output.
