How this service works
Factual directory of x402 pay-per-call services run by MoneyTools for AI agents, plus referral/affiliate links we hold. Contains referral links.
Output
Returns a JSON object with a 'verdict' (e.g. 'ok'), a numeric 'riskScore', an array of 'reasons' explaining the assessment, an array of 'warnings' for potential concerns, and a 'recommendedOption' index pointing to the preferred payment option among those offered by the endpoint.
Example use cases
Safety check before autonomous agent payment
“I'm about to have my agent pay an x402 API at https://api.someservice.com/query — can you precheck the payment terms first and confirm the payTo address isn't on any sanctions list before we send any USDC?”
Validating unknown x402 endpoint config
“I found this x402-gated endpoint at https://api.newprovider.io/inference and I'm not sure if the payment config is legitimate — can you validate the scheme, network, amount, and asset details and give me a risk score?”
Compliance review before integrating x402 API
“Before we integrate this third-party x402 paid API into our product at https://partner.api.xyz/v2/data, please precheck its payment terms and flag any warnings or OFAC concerns with the payTo wallet address.”
Technical details
Endpoint
GEThttps://api.moneytools.dev/v1/precheck?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an AI agent or automated system is about to pay an x402-protected API and you want to validate the payment terms (scheme, network, payTo, amount, asset) and screen the recipient wallet against OFAC sanctions lists before committing funds. Prefer this over blindly calling the paid endpoint when operating autonomously with real USDC, integrating a new or unknown x402 provider, or when compliance and risk assessment are required. It is not charged on errors, making it low-risk to call defensively as a pre-flight check.
Side effects
- Missing or invalid 'url' query parameter — returns an error without charging
- Target URL is not an x402 endpoint or returns no 402 response — may return an error or low-confidence verdict
- Network connectivity issues reaching the target URL
- OFAC screening service unavailable — may delay or fail the check
- Malformed x402 payment header on target endpoint — verdict may reflect parse errors
