Parameter

Type

Description

jobs

array (1–20)

Array of job objects, each with type: "screenshot" or type: "pdf" plus the same fields as the individual tools

Returns a JSON object with credits_used, credits_remaining, and a results array containing index, result (base64), and any error per job.

check_balance

Check remaining API credits and plan details. No parameters.

Notes

  • All render calls use async mode internally and poll until the job completes (up to 5 minutes).

  • Screenshots return MCP image content — agents can display them inline.

  • PDFs return base64-encoded text; agents can save them to disk or pass them on.

  • Errors from the API (rate limits, credit exhaustion, invalid URLs) surface as MCP errors with the original error code.

Requirements

  • Node.js 18+
