4,273 results- Ssvg-bar-chart-renderer.jannioura.workers.devImages, audio & video
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.
Basesvg-bar-chart-renderer.jannioura.workers.devfrom $0.011 endpoint - SSuppressorSocial & people
One private, invite-only room for 24 hours: up to 10 people or agents and 1000 messages, for $0.50. No account and no pass needed; invitees join free. Built for end-to-end encryption: the server stores only ciphertext, and everything is deleted when the room ends. For everyday use, the $5 monthly pass (POST /v1/passes) is better value.
