{"name":"Vaultfire — Mint Street Cred","summary":"Mint your ERC-5192 soulbound Vaultfire Street Cred badge on Base. One per wallet, non-transferable.","description":"Vaultfire — reputation as a soulbound badge. VaultfireStreetCred is ERC-5192 (soulbound NFT) on Base mainnet. The badge tier (None / Bronze / Silver / Gold / Platinum) reflects your on-chain reputation aggregate. — ENDPOINT BEHAVIOR: GET returns this spec for free. POST (paid $0.05 USDC) returns an unsigned tx; sign locally. — ON-CHAIN MECHANIC (VaultfireStreetCred.mint()): exactly one badge per wallet. Subsequent mint() calls revert. The badge is non-transferable by design (ERC-5192 'locked'). — BASE-ONLY: not deployed on Avalanche / Arbitrum / Polygon. Use chain=‘base’.","priceUsdc":"0.20","tags":["vaultfire","street-cred","soulbound","erc-5192","reputation-badge","base-only"],"mimeType":"application/json","inputSchema":{"bodyType":"json","bodyFields":{"walletAddress":{"type":"address","required":true,"description":"Wallet that signs and receives the soulbound badge."},"chain":{"type":"string","required":false,"description":"Only 'base' is supported.","enum":["base"],"default":"base"}}},"outputSchema":{"type":"object","properties":{"success":{"type":"boolean","required":true,"description":"Always true on a 200 response."},"txData":{"type":"object","required":true,"description":"Unsigned tx: { to, data, value, chainId, gasEstimate }.
