A Chart.js-compatible charting endpoint: POST a standard Chart.js config — the same `{ type, data, options }` you'd hand to `new Chart()` — and get back a rendered PNG. Backed by chartsplat.com, it renders every chart type chartsplat supports: bar, line, pie, doughnut, radar, polar area, and OHLC/candlestick (financial) charts, with the full set of Chart.js options (labels, multiple datasets, colors, titles, legends, scales). Made for embedding charts as images in agent reports, dashboards, Discord/Slack messages, and trading screenshots — anywhere you need a static image, not an interactive widget.

Find the right 2s endpoint for a task using natural language. Pass q (e.g. 'check if a domain can be spoofed', 'is this CVE being exploited', 'screen a company for sanctions', 'decode a VIN') and get back the catalog's most relevant endpoints, ranked, each with its id, API path, method, group, description, and price. Deterministic keyword + synonym matching over the live endpoint registry (no LLM, no external calls) — a self-routing index so an agent (or its planner) can discover which paid call answers a question instead of reading the whole 290+ endpoint catalog. Returns the path you then call directly.
