Emboss turns any PDF form into a fillable one, fills it from data or supporting documents, reads a filled form back, and faxes the result to a US, Canadian or Mexican fax number. It can make a flat PDF fillable, complete a form from data, fill a PDF form from data or from supporting context documents, batch fill forms from a spreadsheet, one row per output file, and send a finished PDF by fax and track its delivery. Use it whenever an agent needs to fill a PDF form, generate many filled copies of the same form, inspect a form's fields before filling it, or fax a document to an agency. Get a price quote for filling a PDF form before any paid work runs, free, then execute it once you have seen the price. Slower skills may answer working at first: check the task (GetTask) for the result. No account needed: pay per job with x402 (USDC on Base) for one-off, anonymous use, priced dynamically per page -- or sign in with an Emboss account for monthly invoice billing across every call. A pay-per-call API is also available at https://api.getemboss.ai/pay using MPP (Machine Payments Protocol, Stripe + Tempo), for agents that speak plain HTTP rather than A2A. Signed-in callers can also describe the job in plain language instead of naming a skill; Emboss picks the skill, asks when something is missing, and confirms a fax number before sending. It can also run several jobs in a row, such as fill then fax, after you confirm the plan.

Upload media, get back transcripts, summaries, ranked clip candidates, and ready-to-post short-form cuts — billed per call via [MPP](https://mpp.directory/) (Tempo USDC) or Stripe Checkout for browser MCP hosts. ## Tools - **`transcribe`** — SRT transcript from any audio/video file. _$0.50 audio · $1.00 video_ - **`summarize`** — long-form summary + transcript. _$0.75 audio · $1.25 video_ - **`find_clips`** — ranked clip candidates from a video, with timestamps, scores, and a free transcript byproduct. Optional `query` for needle-in-haystack mode. _$2.00_ - **`extract_clip`** — cut/compose one or more segments from a parent video job into a single .mp4 (with optional time-shifted transcript). _$0.50_ - **`extract_vertical_clip`** — 9:16 mobile-ready cut for TikTok / Reels / Shorts, loudness-normalized. _$0.50_ - **`complete_upload`** / **`get_job_status`** — finish the upload after the presigned PUT, then poll for results. *More coming soon* ## How it works 1. Call a paid tool with a filename → get back a `payment_required` response carrying an MPP challenge (and a Stripe Checkout URL for browser hosts without a wallet). 2. Sign the challenge with `mppx` (or pay via Checkout) and call the tool again with `payment_credential`. 3. Receive a presigned upload URL, `PUT` the bytes, call `complete_upload`, poll `get_job_status` until done. For derivative cuts, pass the parent `find_clips` job_id as `source_job_id` to `extract_clip` / `extract_vertical_clip` — within 72h there's no re-upload and no re-transcribe, just $0.50 per cut. ## Endpoints - MCP: `https://api.weftly.ai/mcp` (Streamable HTTP, JSON-RPC 2.0) - Web UI: `https://chat.weftly.ai` - Discovery: `/.well-known/mpp.json` · `/.well-known/openapi.json` · `/.well-known/cards/{tool}.md` Failed jobs auto-refund. Source media is purged after the job's TTL (4h ephemeral / 24h session / 72h for `find_clips` parents).
