Briefs API — generate, stream, export, and share briefs

Briefs transform completed research into a structured market analysis document — market map, incumbent analysis, emerging players, feature landscape, market gaps, positioning, and MVP angle. Sections are generated in parallel and streamed as they complete, so you can display partial content immediately rather than waiting for the full document. Each brief is revisioned, diffable, and exportable to PDF or as a shareable App Clip page.

Create a brief

project_id

string

required

UUID of the project to create the brief for. The server uses the project’s latest completed research to generate the brief.

research_id

string

UUID of a specific research run to use. When omitted, the server picks the most recent completed research for the project.

template

string

Optional template name to vary the brief structure or tone. Pass null for the default template.

curl -X POST https://api.manticscore.com/briefs \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{"project_id": "9f4e2a1b-..."}'

201 response

{
  "brief_id": "e3f8a1d2-...",
  "status": "generating"
}

Returns 404 if the specified research_id is not found or has not completed. Returns 422 if the project has no completed research at all.

Stream section progress immediately from GET /briefs/{brief_id}/events. You can also poll GET /briefs/{brief_id} — it returns whatever sections have been written so far, even during generation.

Briefs can also be created automatically. The first time a Forge run on a project opens a pull request, the server bootstraps a brief for that project (using the latest completed research with audience: "founder") if one does not already exist, then appends a progress section that summarizes the PR. Subsequent PRs upsert items into that same progress section keyed by pr_number and bump brief.revision. You will see these auto-created briefs in GET /briefs alongside ones you created explicitly.

List briefs

limit

number

default:"20"

revision

number

required

Increments each time a section is regenerated. Use with the diff endpoint.

quality_score

number

required

0–100 quality score computed from section completeness and source confidence.

Token for the public share link. Present once the brief has been shared.

Get a brief

Returns the full brief with all sections that have been written so far. During generation, sections complete progressively — poll this endpoint or stream events to track progress.

}

market_map

object

Structured map of the competitive landscape.

incumbents

array

Analysis of established competitors.

emerging

array

Analysis of newer entrants and challengers.

features

array

Feature comparison across competitors.

market_gaps

array

Identified opportunities not well-served by existing products.

positioning

object

Recommended positioning for your product.

mvp_angle

object

Suggested MVP scope and angle based on the market gaps.

progress

object

Optional auto-maintained section that tracks Forge pull requests opened against this project. Has shape {"title": "Progress", "items": [{"pr_number": 42, "pr_url": "...", "summary": "...", "appended_at": "..."}]}. Items are upserted on pr_number, so re-emitting the same PR is idempotent. Absent on briefs that have never had a PR auto-appended.

section_meta

object

Per-section metadata keyed by section name. Each value contains a quality_score and generated_at timestamp.

sources

object[]

Web sources consulted during generation. Each source includes a url, title, snippet, and a confidence score.

Stream brief generation events

Subscribe to the live NDJSON stream as the brief’s sections are written. Reconnect at any sequence number using the cursor.

cursor

number

default:"0"

Resume from this event sequence number.

curl -N "https://api.manticscore.com/briefs/e3f8a1d2-.../events?cursor=0" \
  -H "Authorization: Bearer <token>"

Each line is a JSON object with shape {"v": 1, "event": "<type>", "data": {...}}. The event types are:

Event	Description
`section_progress`	A section has been written. Data contains the section name and content.
`brief_ready`	All sections are complete. The brief is fully generated.
`error`	A fatal error occurred.
`done`	Stream is closed. Always the last event.

Regenerate a section

Re-runs generation for a single section of the brief. Increments the brief’s revision counter. Use the diff endpoint afterwards to compare what changed.

section_type

string

required

The section to regenerate. One of: market_map, incumbents, emerging, features, market_gaps, positioning, mvp_angle.

curl -X POST "https://api.manticscore.com/briefs/e3f8a1d2-.../sections/incumbents/regenerate" \
  -H "Authorization: Bearer <token>"

200 response

{
  "status": "regenerating",
  "section_type": "incumbents",
  "revision": 2
}

Diff brief revisions

Compare the current version of the brief against an earlier revision to see which sections changed.

from_revision

number

The earlier revision to compare from. Omit to compare against the immediately previous revision.

curl "https://api.manticscore.com/briefs/e3f8a1d2-.../diff?from_revision=1" \
  -H "Authorization: Bearer <token>"

200 response

{
  "from_revision": 1,
  "to_revision": 2,
  "changes": 3,
  "diff": [
    {
      "section_type": "incumbents",
      "change": "modified"
    }
  ]
}

Build a graph from a brief

Generates a build graph using the features in the brief. Returns immediately — the graph is built in the background.

  "features_selected": 5
}

format

string

default:"pdf"

Export format. Currently only pdf is supported.

curl "https://api.manticscore.com/briefs/e3f8a1d2-.../export?format=pdf" \
  -H "Authorization: Bearer <token>" \

  "slug": "brief-e3f8a1d2"
}
