What This Tool Does#

IPFS Content Gateway provides access to the InterPlanetary File System, a decentralized peer-to-peer network for storing and sharing content using content-addressed identifiers. The retrieval function fetches data from IPFS by CID (Content Identifier) with automatic failover across seven public gateways including ipfs.io, Cloudflare IPFS, and Pinata, ensuring high availability even when individual gateways are slow or unavailable. Content retrieval automatically detects whether the response is text or binary data and returns appropriate previews with full metadata including content type, size, and response headers. The upload function accepts base64-encoded files up to 10MB and pins them to IPFS through pinning services that ensure content remains available on the network. Users can provide their own API credentials for Pinata, Web3.Storage, or NFT.Storage, or use shared infrastructure for convenience. Each upload returns the permanent CID along with multiple gateway URLs for immediate access. The list function provides a complete history of uploads including filenames, sizes, upload dates, and ready-to-use gateway links, with aggregate statistics on total storage used.

Product Instructions#

IPFS Content Gateway#

Store and retrieve files on the InterPlanetary File System (IPFS) -- a decentralized, content-addressed storage network. Upload files up to 10MB, retrieve content by CID, and list your upload history.

Actions

retrieve

Fetch content from IPFS by its Content Identifier (CID). Supports both CIDv0 ( Qm...) and CIDv1 ( bafy...) formats. Multiple gateways are tried automatically for reliability.

Required fields:

• action — "retrieve"
• cid — The IPFS Content Identifier to retrieve

Example:

json

{
  "action": "retrieve",
  "cid": "QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG"
}

Response includes: content (text preview up to 10,000 chars or binary indicator), content_type, content_length, gateway_url, and ipfs_url.

---

upload

Upload a file to IPFS. The file is pinned so it remains available on the network. Maximum file size is 10MB.

Required fields:

• action — "upload"
• content — Base64-encoded file content
• filename — Original filename with extension (e.g., "report.pdf")

Optional fields:

• pinning_api_key — Your own pinning service API key for unlimited uploads
• pinning_service — Which service your API key is for. Required when pinning_api_key is provided. One of: "pinata", "web3storage", "nftstorage"

Example (using shared service):

json

{
  "action": "upload",
  "content": "SGVsbG8gV29ybGQh",
  "filename": "hello.txt"
}

Example (using your own Pinata key):

json

{
  "action": "upload",
  "content": "SGVsbG8gV29ybGQh",
  "filename": "hello.txt",
  "pinning_api_key": "your-pinata-jwt-token",
  "pinning_service": "pinata"
}

Response includes: cid, filename, file_size_bytes, file_size_mb, ipfs_url, and multiple gateway_urls for accessing the content.

---

list

List all files you have previously uploaded through this tool, sorted by most recent first.

Required fields:

• action — "list"

Example:

json

{
  "action": "list"
}

Response includes: array of uploads (each with cid, filename, file_size, upload_date, ipfs_url, gateway_url), plus totals for upload count and combined size.

---

Common Workflows

Store a document permanently

1. Base64-encode your file content
2. Use upload with the encoded content and filename
3. Save the returned CID -- this is the permanent address of your content

Retrieve previously stored content

1. Use retrieve with the CID you received from an upload or found elsewhere
2. Text content is returned directly; binary content is identified by type

Review your upload history

1. Use list to see all files you have uploaded
2. Each entry includes the CID and gateway URL for easy access

Important Notes

• File size limit: 10MB maximum per upload
• Content encoding: Files must be base64-encoded before uploading
• CID formats: Both CIDv0 ( Qm...) and CIDv1 ( bafy...) are supported for retrieval
• Persistence: Uploaded content is pinned to IPFS, meaning it will remain available as long as the pinning service maintains it
• Gateway fallback: Retrieval automatically tries multiple gateways if the first one fails
• Own credentials: For heavy usage, provide your own API key from Pinata, Web3.Storage, or NFT.Storage to avoid shared service limits

Actions And Schema#

Complete generated action schema: ./schema.md. Supported action count: 3. x402 availability: not enabled for this product.

• list (action slug: list): List all files previously uploaded through this tool, sorted by most recent first. Returns upload history with CIDs, filenames, sizes, dates, and gateway URLs. Price: 3 credits. Parameters: none.
• retrieve (action slug: retrieve): Fetch content from IPFS by its Content Identifier (CID). Supports both CIDv0 (Qm...) and CIDv1 (bafy...) formats. Multiple gateways are tried automatically for reliability. Price: 20 credits. Parameters: cid.
• upload (action slug: upload): Upload a file to IPFS. The file is pinned so it remains available on the network. Maximum file size is 10MB. Files must be base64-encoded before uploading. Price: 20 credits. Parameters: content, filename, pinning_api_key, pinning_service.

Live Schema And Examples#

Use the compact schema above for ordinary calls. Before a new production integration, or whenever parameters, enum values, nested objects, outputs, or examples are unclear, fetch live details first.

• Exact schema: call agentpmt-tool-search-and-execution with action: "get_schema", and tool_id: "ipfs-content-gateway".
• Detailed examples: call agentpmt-tool-search-and-execution with action: "get_instructions" and tool_id: "ipfs-content-gateway", or call this product with action: "get_instructions" when the product tool is already selected.
• Treat returned live schema and instructions as more specific than this generated summary.

MCP schema lookup through the main AgentPMT MCP server:

json

{
  "method": "tools/call",
  "params": {
    "name": "AgentPMT-Tool-Search-and-Execution",
    "arguments": {
      "action": "get_schema",
      "tool_id": "ipfs-content-gateway"
    }
  }
}

json

{
  "action": "get_instructions",
  "tool_id": "ipfs-content-gateway"
}
