Jobs and files
- Up to 20 input files and 8 steps per job; a call waits for its job up to 60 seconds.
- Files sent in the request body: up to 25 MB (larger ones use an upload URL).
- Files and results are deleted after 24 hours; download links last an hour.
metadataon a job: up to 20 string keys and values.
Assistants use your plan
When Claude, ChatGPT or another assistant signs in to your account through the MCP server, its work counts against your fynepdf.com plan (tasks and AI allowance), not your credits.
- Smart Edit follows the website's rules: its files a day, and its changes per file.
- AI calls (ask, summarize, extract) also have a fair-use limit of 200 a day on Free and 1,000 on paid plans, counted from 00:00 UTC. A person asking questions doesn't reach it.
- The Library (list, open, save) works only for an assistant signed in this way, never with an API key.
