Kleros IPFS Upload (x402)

Upload Kleros-ecosystem files to IPFS via https://kleros-ipfs-gateway.fly.dev/upload-to-ipfs, an x402-protected gateway that charges $0.01 USDC per upload on Base mainnet. The returned IPFS CID is content-addressable and dereferenceable through any IPFS gateway, and indexed by Kleros's Graph Node for subgraph discoverability.

The gateway is a thin reverse-proxy in front of a Filebase-backed pinning service operated by Kleros. Every upload is pinned to Filebase indefinitely as long as Kleros runs the gateway — a reasonable assumption for artifacts the Kleros ecosystem itself depends on (the team has a strong incentive to keep this live), but not a substitute for a general-purpose pinning provider if the content is unrelated to Kleros.

When to use this skill

Trigger this skill when the user is uploading Kleros-ecosystem content:

• Dispute evidence attachments — screenshots, documents, contracts, transcripts.
• Meta-evidence JSON — the policy/spec referenced by a court or arbitrator smart contract at dispute creation.
• Court / dispute / arbitrator policies — JSON describing rules, fees, juror counts, appeal mechanics.
• Kleros Curate item metadata — JSON for items submitted to a Curate list (e.g. tokens, badges).
• Juror / arbitrator justifications — rulings, dissents, deliberation rationale.
• Any artifact whose CID will end up in a Kleros smart contract event, transaction, or subgraph.
• The user explicitly names this gateway (kleros-ipfs-gateway.fly.dev etc.) or this skill.
• The user is asking the agent to test, validate, or sanity-check this gateway or this skill itself (e.g. "smoke-test the Kleros IPFS gateway" / "verify pay-and-upload works"). A deliberate end-to-end test is a legitimate trigger even if no Kleros artifact is being uploaded for real use.
