Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • browse_marketplaceBrowse Marketplaceread-only

    Search and browse active listings on the Payaion marketplace. Filter by keyword, category, and paginate through results. Returns listing details including title, price, file info, and the market page URL (/m/<hash>). No API key required over stdio.

  • create_folderCreate Folder

    Create a storage folder. Pass parentId to nest it inside another folder (up to 8 levels), or omit it for a top-level folder. Names are unique among siblings and cannot contain slashes.

  • delete_folderDelete Folder

    Delete a folder and its subfolders. Files are NOT deleted — they move back to the storage root. Deleting the files themselves is a separate, explicit action.

  • delist_from_marketplaceDelist from Marketplace

    Take your listing off the public Payaion marketplace. The file itself is not deleted and its share link keeps working. Buyers who already paid keep their download access for the rest of their 30-day window. Requires the agent key owner to own the listing.

  • get_download_urlGet Download URLread-only

    Get a fresh shareable download URL for a previously uploaded file. The file must be in READY status. Share this URL with anyone — it works without authentication. Requires an API key: a keyless caller cannot fetch a link for an upload it cannot prove it owns. Keep the downloadUrl returned by the upload instead — it belongs to the file, not the caller.

  • get_payment_requirementsGet Payment Requirementsread-only

    Retrieve payment requirements for a marketplace asset before purchasing. Returns whether the asset is free or paid. For paid assets, includes the x402 payment requirements object that must be signed by the buyer's wallet and passed to the purchase_asset tool.

  • get_upload_statusGet Upload Statusread-only

    Check the processing status of a previously uploaded file. Returns the current status (PENDING_UPLOAD, UPLOADING, READY, FAILED) and whether the file is ready for download. Rarely needed — the 'transfer' tool handles polling automatically. Use this only to check on uploads that timed out or for manual status inspection.Over stdio no API key is required: without one you upload as a guest (100 MB, 24-hour link); a key raises the limits and lets you sell.

  • list_on_marketplaceList on Marketplace

    List an already-uploaded file on the public Payaion marketplace. The upload must be READY status and have a price set. Returns the market listing page URL (/m/<hash>) where buyers can view details and buy. Requires the agent key owner to own the upload.

  • list_storageList Storageread-only

    List the account's storage: every folder (with its full path and file count) plus the files inside one folder. Omit folderId to list files sitting at the root. Also returns bytes used against the plan limit. Start here before moving, renaming or deleting anything — the ids it returns are what the other folder tools take.

  • move_fileMove File to Folder

    Move an uploaded file into a folder, or pass folderId: null to move it back to the storage root. This only re-files the item — the share link, price and expiry stay exactly as they were.

  • purchase_assetPurchase Assetcan change or delete data

    Finalize the purchase of a paid marketplace asset. Requires a signed x402 payment payload from the buyer's wallet. First call get_payment_requirements to obtain the payment requirements, sign them with your EVM wallet, then pass the signed payload here. Returns the purchase receipt including a directDownloadUrl — you can GET that URL with your X-Aion-Key header to download the file immediately, no extra steps needed.

  • transferTransfer File

    One-shot file transfer with optional pricing and marketplace listing. Upload a file, set a per-download price, and list on the marketplace — all in a single call. Returns a shareable download URL. Supports free transfers, paid downloads, and marketplace listings. Provide EXACTLY ONE of: 'filePath' (local stdio — zero tokens), 'url' (remote fetch), or 'content' (base64 fallback).Over stdio no API key is required: without one you upload as a guest (100 MB, 24-hour link); a key raises the limits and lets you sell.

  • update_folderRename or Move Folder

    Rename a folder, move it under a different parent, or both. Pass parentId: null to move it back to the top level. A folder cannot be moved inside itself or its own subfolders.

  • upload_fileUpload File

    Low-level upload. Prefer the 'transfer' tool instead — it handles polling automatically. This tool returns immediately with PENDING_UPLOAD status; you must poll get_upload_status yourself. Max file size follows the account plan (Basic 500 MB / Pro 1 GB). Provide EITHER 'filePath' (local stdio only) OR 'content' (base64). Use only when you need explicit control over the upload lifecycle.Over stdio no API key is required: without one you upload as a guest (100 MB, 24-hour link); a key raises the limits and lets you sell.

  • upload_from_urlUpload from URL

    Low-level upload from URL. Prefer the 'transfer' tool instead — it handles polling automatically. This tool returns immediately with PENDING_UPLOAD status; you must poll get_upload_status yourself. Max file size follows the account plan (Basic 500 MB / Pro 1 GB). Private/internal URLs are blocked. Use only when you need explicit control over the upload lifecycle.Over stdio no API key is required: without one you upload as a guest (100 MB, 24-hour link); a key raises the limits and lets you sell.
