How this service works
Generic on-chain read against any of the 134 Vaultfire Protocol contracts across Base, Avalanche, Arbitrum, and Polygon. Pass { chain, contract (name or address), function, args } and receive the decoded return value plus block provenance. Read-only (view/pure) calls only.
Output
Returns the decoded return value of the called contract function (e.g. a uint, address, struct, or array), along with block provenance including block number and chain identifier, wrapped in a JSON response.
Example use cases
Example prompt
“Call the getAgentScore function on the Vaultfire ReputationRegistry contract on Base, passing the address 0x0000000000000000000000000000000000000001, and give me the decoded result with block info.”
Technical details
Endpoint
POSThttps://theloopbreaker.com/api/x402/contract-call?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to read on-chain state from any of the 134 Vaultfire Protocol contracts across Base, Avalanche, Arbitrum, or Polygon and want a single unified interface that handles ABI lookup and decoding automatically. Prefer this over raw RPC calls when you don't want to manage ABIs or multi-chain RPC endpoints yourself. It's ideal for agent workflows that need to inspect Vaultfire reputation, bond, governance, or registry data programmatically.
Side effects
- Contract name not found in the 134-contract Vaultfire registry — returns an error identifying unknown contract
- Function name does not exist on the specified contract — returns ABI mismatch or revert error
- Wrong argument types or count passed — returns decoding or revert error
- Chain not supported (only Base, Avalanche, Arbitrum, Polygon) — returns unsupported chain error
- Missing X-PAYMENT header — returns 402 with payment requirements
- RPC node unavailable for the target chain — returns upstream connectivity error
- Function is not view/pure (write function attempted) — returns rejection since only read-only calls are supported
