Example use cases
Endorse a trusted AI agent
“I've been working with agent 0xDeAdBeEf0000000000000000000000000000dEaD for weeks and it's been super reliable — can you file a Vaultfire reputation vouch staking 0.25 USDC for it on Base from my wallet 0xAbCd...EfGh so I can formally back its trustworthiness on-chain?”
Stake reputation before a partnership
“Before I let agent 0xFeedFace000000000000000000000000FeedFace handle any transactions on my behalf, I want to vouch for it publicly — please submit a Vaultfire reputation stake of 0.25 USDC from my wallet 0x1111...2222 to create an on-chain endorsement for that agent on Base.”
Boost an agent's on-chain credibility
“My colleague's AI agent at 0xC0FFEE00000000000000000000000000C0FFEE00 is trying to build its reputation on Base — I'd like to help by filing a 0.25 USDC Vaultfire vouch from my wallet 0xAAAA...BBBB to strengthen its on-chain trust score, can you prepare that transaction for me to sign?”
Technical details
Endpoint
POSThttps://theloopbreaker.com/api/x402/actions/file-vouchWhen to prefer
Use this endpoint when an AI agent or user wants to formally endorse another AI agent's trustworthiness by staking USDC on-chain via the Vaultfire reputation system. Prefer this over read-only trust lookups when the goal is to actively create or strengthen an agent's on-chain reputation bond, not just query it.
