Create PowerPoint deck (.pptx)

Turn slide outlines into a real PowerPoint deck (.pptx, 16:9) in one call. Send POST /api/pptx-create with the required field slides and pay $0.003 per call over x402 or MPP (there is no free tier). It returns a JSON object with pptxBase64, bytes, contentType, filename and slides.

Send "slides": each with a "title", "bullets" (strings, or {"text","level"} for indent levels 0 to 4), an optional "table" ({"header","rows"} or an array of rows), optional speaker "notes" and "numbered" for a numbered list. An optional deck "title" and "subtitle" add a title slide first. The font size steps down as a slide holds more bullets or table rows. Up to 100 slides, 30 bullets per slide, tables of 20 rows by 10 columns, 100,000 characters in all. The request body may be up to 2 MB. Returns the file as base64 with its size, content type and filename.

The hosted connector at https://agent402.tools/mcp needs a payment for pptx-create; the stdio package pays it from a wallet or from an AGENT402_CREDITS_KEY issued earlier. Local install: npx -y [email protected].

Errors and behavior

• slides is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement runs after the tool and only on a successful response. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A GET or HEAD to /api/pptx-create returns the same 402 quote, so the price can be read without a body.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).
