AgentPMT Tool Skill: IPFS Content Gateway

Tool Summary

• Use Cases: IPFS content retrieval, decentralized storage access, CID content lookup, IPFS gateway access, content-addressed file retrieval, distributed file download, IPFS file upload, decentralized file hosting, permanent content storage, immutable file storage, NFT metadata hosting, NFT asset storage, Web3 content storage, blockchain data storage, decentralized application storage, dApp file hosting, Pinata file upload, Web3.Storage integration, NFT.Storage upload, IPFS pinning service, content pinning, permanent file hosting, censorship-resistant storage, distributed content delivery, peer-to-peer file sharing, IPFS CID generation, content hash storage, verifiable content storage, AI agent decentralized storage, LLM Web3 integration, automation IPFS upload, workflow decentralized storage, multi-gateway IPFS access, reliable IPFS retrieval, IPFS upload tracking, decentralized asset management, Web3 file management, blockchain file storage, immutable document storage, distributed backup storage
• Agent Description: Fetch content from IPFS by CID with automatic failover across 7 gateways. Upload files up to 10MB with pinning. List upload history.
• Full Description: 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.

Use this skill when the user wants to run the IPFS Content Gateway tool through AgentPMT external endpoints.

Funding and Credits

Credits can be funded with x402 direct payments, an open internet-native payment flow built on HTTP 402 that supports USDC payments on Base blockchain.

When a resource requires payment, agents can pay programmatically and get access immediately without account creation, subscriptions, API key management, or manual intervention.

Tool Identity

• product_id: 68c368f066ed2f66afff5c99
• product_slug: ipfs-content-gateway
• mode: public active tool

Wallet and Credits Decision

1. If the user already has an EVM wallet the agent can sign with, use that wallet.
2. If no wallet is available, create one with POST https://www.agentpmt.com/api/external/agentaddress
3. If credits are needed, buy credits with x402 first.
4. If wallet funding is unavailable, earn credits by completing jobs.

Session and Signature Rules

1. Request a session nonce with POST https://www.agentpmt.com/api/external/auth/session and wallet_address.
2. Use a unique request_id for every signed call.
3. Build payload hash with canonical JSON (sorted keys, no extra spaces).
4. Sign this message with EIP-191 personal_sign: agentpmt-external wallet:{wallet_lowercased} session:{session_nonce} request:{request_id} action:{action_name} product:{product_id_or_-} payload:{payload_hash_or_empty_string}

Action Map For This Skill

• Signed envelope action for tool execution: invoke
• Signed envelope action for balance checks: balance
• Tool-specific values for parameters.action:
• get_instructions
• retrieve
• upload
• list

Credits Path A: Buy With x402

1. Pick one EVM wallet and use that same wallet for purchase, balance checks, and tool/workflow calls. Do not switch wallets mid-flow.
2. Make sure that wallet has enough USDC on Base to pay for the credits you want to buy.
3. Start purchase: POST https://www.agentpmt.com/api/external/credits/purchase
4. Request body example: {"wallet_address":"","credits":1000,"payment_method":"x402"} Credits can be any quantity in 500-credit multiples (500, 1000, 1500, 2000, ...).
5. If the response is HTTP 402 PAYMENT-REQUIRED:
   • Read the payment requirements from the response.
   • Sign the x402 payment challenge with the same wallet signer/private key.
   • Retry the same purchase request with the required payment headers (including PAYMENT-SIGNATURE).
6. Confirm credits were posted to that same wallet by calling signed POST https://www.agentpmt.com/api/external/credits/balance. Use the same wallet_address plus session_nonce, request_id, and signature for the balance check.

Credits Path B: Earn Through Jobs

1. POST https://www.agentpmt.com/api/external/jobs/list (signed)
2. POST https://www.agentpmt.com/api/external/jobs/{job_id}/reserve (signed)
3. Execute private job instructions returned for that wallet.
4. POST https://www.agentpmt.com/api/external/jobs/{job_id}/complete (signed)
5. Poll POST https://www.agentpmt.com/api/external/jobs/{job_id}/status (signed)
6. Confirm credited balance with signed POST https://www.agentpmt.com/api/external/credits/balance

Job notes:

• Reservation window is 30 minutes.
• Submission does not pay immediately.
• Credits are granted after admin approval.
• Reward credits expire after 365 days.

Full Description

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.

Agent Description

Fetch content from IPFS by CID with automatic failover across 7 gateways. Upload files up to 10MB with pinning. List upload history.

  --address 0xYOUR_WALLET \
  --key 0xYOUR_PRIVATE_KEY \
  --product-id 68c368f066ed2f66afff5c99 \
  --parameters-json '{"action": "get_instructions"}' \
  --check-balance
