How this service works
Brief to PDF. Send a short brief; returns a 400 to 900 word document written from it, laid out as an A4 PDF (base64 in JSON) plus the Markdown text. Use for a one-page explainer, memo or checklist. It uses only the facts in the brief and general knowledge; no web search. Typical response 5 to 15 s. Failed calls are not charged.
Output
A JSON object containing the PDF as a base64-encoded string (pdf_base64), the document's Markdown text, a suggested filename, file size in bytes, content type (application/pdf), and a creation timestamp. The PDF is formatted as an A4 page, 400–900 words, generated from the supplied brief.
Example use cases
Executive memo from bullet points
“Take these notes and turn them into a clean one-page PDF memo titled 'Product Launch Plan': 'We are launching our new analytics dashboard on November 1st. Key audiences are enterprise clients. Marketing will run a webinar series in October. Support team needs to be briefed by Oct 15th. Pricing starts at $299/month.'”
Onboarding checklist for new hires
“Generate a PDF checklist titled 'New Employee Onboarding Checklist' from this brief: 'New hires must complete HR paperwork on day 1, set up their laptop using IT instructions, join the company Slack, attend a 30-min orientation session, and meet their assigned buddy within the first week.'”
One-page explainer for a stakeholder
“Write a one-page PDF explainer titled 'What is Zero-Trust Security?' from this brief: 'Zero-trust is a cybersecurity model that assumes no user or device is trusted by default, even inside the corporate network. It requires continuous verification, least-privilege access, and micro-segmentation. Intended audience: non-technical board members.'”
Technical details
Endpoint
POSThttps://quantagentshop.com/v1/pdf/from-brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a short text brief and need a ready-to-deliver, professionally laid-out A4 PDF (and its Markdown source) without doing any web research — ideal for memos, one-page explainers, and checklists. Prefer the sibling Markdown-to-PDF endpoint if you already have structured Markdown, or the web-page-to-PDF endpoint if you need to capture an existing URL. This endpoint excels when the content needs to be drafted and formatted in a single call from raw notes.
Side effects
- Brief shorter than 20 characters returns a validation error
- Brief exceeds 2000 characters and is rejected
- Malformed JSON body causes a 400 error
- Service timeout on rare occasions beyond the 5–15s window; failed calls are not charged
- Title exceeding 120 characters is rejected
