x402
KushBitx AgentProof Quick Check is a paid API for AI agents from kushbitx.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).
Performs a deterministic Base chain identity and official USDC contract-presence check, returning a PASS/FAIL status with chain ID and contract code verification.

How this service works
A deterministic Base chain identity and official USDC contract-presence check. No request body. Not a token-risk report, transaction simulation, or payment proof.
Output
Returns a JSON object with a top-level 'status' field ('PASS' or 'FAIL'), the network identifier ('eip155:8453'), and a 'checks' object containing: a 'chainId' sub-object with expected (8453), observed value, and a boolean match flag; and a 'usdcContract' sub-object with the contract address and a boolean 'codePresent' flag indicating whether bytecode exists at that address on Base.
Example use cases
Pre-payment chain sanity check
“Before my agent sends any USDC on Base, verify that we're actually connected to the right chain — chain ID 8453 — and that the USDC contract address has real code on it.”
Agent startup environment validation
“When my AI agent boots up, I want it to confirm it's on the Base mainnet and that the official USDC contract is live and present before it does anything financial.”
Detecting misconfigured network in CI
“In my CI pipeline for my Base-deployed agent, run the AgentProof quick check to catch any cases where the RPC is pointing at the wrong chain or the USDC contract is missing.”
Technical details
Endpoint
GEThttps://kushbitx.com/api/agentproof-quick-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a cheap, fast, deterministic sanity check that it is operating on the correct Base chain (ID 8453) and that the canonical USDC contract has deployed bytecode — before initiating any payments or on-chain actions. Prefer this over a full transaction simulation or token-risk report when you only need a binary PASS/FAIL environment check, not risk analysis or spend authorization.
Side effects
- Chain ID mismatch — observed chain ID differs from expected 8453, status returns FAIL
- USDC contract code not present — no bytecode found at the expected address, codePresent returns false
- Upstream RPC or node unavailability — endpoint may return an error or timeout
- Payment not included — x402 payment of 0.001 USDC required per call; missing payment returns 402
