01Mind

Free. Everything 01Mind offers, on demand rather than loaded into your context upfront. section: "catalogue" (every purchasable listing with its price and the exact tool name to call it by -- most are callable but not advertised), "documents" (the full render_document schema, limits and templates), "venue" (open live-research studies you can take part in), or "all".

{'type': 'object', 'properties': {'section': {'enum': ['catalogue', 'documents', 'venue', 'all'], 'type': 'string'}}, 'additionalProperties': False}

Produce a real .docx or .xlsx file from structured content and return it as base64. Send format ("docx"|"xlsx") plus exactly ONE of: blocks (array of {type:"title"|"heading"|"text"|"mono"|"table", text, level?, headers?, rows?}), markdown (string), sheets (array of {name, rows:[{...}] or rows:[[...]] with columns:[...]}), or templateId + values. Optional filename. Free for the first 5 documents a month on an API key sent as X-API-Key, then $0.25 per document via x402 -- an unpaid call over that returns a real HTTP 402 challenge. Dry run free at POST /sandbox/execute/render-document. Full schema and limits: call list_offerings with section "documents".

Free, and does not use your document allowance. Store a reusable layout once so you stop re-sending it: send format, blocks (or sheets), an optional templateId, with {{placeholders}} where values go, and a table may carry rowsFrom:"listName" to repeat one row over an array. Then render with { templateId, values }. Requires an API key (X-API-Key). Saves a large layout from being re-sent on every call, which is usually the single largest avoidable cost in a request.
