Use Case Recommendations
Best for: PreReason
PreReason is a market context API designed to be consumed by AI agents rather than by dashboards, and the design follows from that premise more rigorously than most 'AI-ready' data products. It pulls Bitcoin on-chain metrics, macro indicators, mining and liquidity data from six-plus sources and returns them pre-reasoned: trend direction as rising, falling or flat, 7/30/90-day momentum, percentile rankings, cross-asset correlations, regime classification and confidence scores, all in one structured response. The alternative an agent developer otherwise faces is integrating five data sources, parsing raw numbers and building an interpretation layer, which is where most agent projects lose their time. The delivery detail worth noting is the LLM-native markdown format: responses are formatted for how language models read rather than as JSON, which the vendor measures at roughly 60% fewer tokens for the same content. Given that agents pay per token on every call, that is a direct cost reduction, not a formatting preference. Distribution is agent-first throughout — REST API, an MCP server installable with npx @prereason/mcp, and llms.txt — working with Claude Desktop, Claude Code, Cursor and Windsurf. Eighteen market briefings are split six free, six on Basic and six on Pro, with the free tier allowing 60 requests an hour and 500 a day against 30 days of rolling data, no card required.
Ideal use cases:
- •Teams or individuals who need pre-reasoned trend direction, momentum, percentiles and regime classification
- •Teams or individuals who need llm-native markdown responses using ~60% fewer tokens than json
- •Teams or individuals who need mcp server installable with npx, plus rest api and llms.txt
- •Teams or individuals who need cross-asset correlations computed from 6+ sources
- •Anyone focused on mcp workflows
- •Anyone focused on api workflows
Best for: Szum
Szum is an opinionated chart design system rather than a charting library: you supply data and intent, and it produces a validated, publication-ready chart under a compact grammar with six curated themes that coordinate typography, color, axes, labels and spacing together. Change the theme and the entire chart moves as one, which is the thing hand-rolled Recharts or matplotlib output never manages across a document. The interesting engineering is the validation layer, and it is built with agents in mind. Every edit is checked before it commits: if a mark references a field that does not exist in the resolved data rows, the change is blocked, the last valid chart stays live, and the error names the offending channel, the missing field and the fields that are actually available. An agent that writes a broken chart definition gets a specific, machine-actionable correction instead of a silently wrong picture — and Szum offers an explicit fix when it can verify the repair. You can start wherever you already work: ask ChatGPT or Claude over MCP, use the browser editor, call the API and SDK for PNG and SVG rendering, or create on canvas through the Figma plugin. All four paths build the same chart definition, which can then be exported as an image, an editable Figma asset, a Slack or Notion share, or a responsive interactive embed with tooltips and legend controls behind one iframe. The vendor reports 40,000+ charts rendered.
Ideal use cases:
- •Teams or individuals who need validation blocks invalid edits and keeps the last valid chart live
- •Teams or individuals who need six curated themes that move typography, color and spacing together
- •Teams or individuals who need mcp, web editor, api/sdk and figma plugin all build one definition
- •Teams or individuals who need metered on renders, not views — cached cdn reads are free
- •Anyone focused on charts workflows
- •Anyone focused on data-visualization workflows
