How this service works
Procedure for evaluating whether a hot agent wallet should be wired to a per-request x402 endpoint before first payment. Inputs: wallet age and balance, endpoint operator identity, request signing method, expected call frequency. Outputs: exposure score 0-100, signing-fatigue risk when expected calls exceed 20 per hour per session, payment-request forgery checks (mutating a signed request body or amount must invalidate the signature), quota-drain detection rule (reject payees whose response
Output
Returns a JSON object with an exposure score from 0 to 100, a signing-fatigue risk flag triggered when expected calls exceed 20 per hour per session, a payment-request forgery check result verifying that mutating a signed request body or amount invalidates the signature, a quota-drain detection rule for rejecting high-risk payees, and a prose decision brief for the agent.
Example use cases
High-frequency session risk check
“My agent is about to start making 40 x402 payments per hour to a new data endpoint — can you run an exposure assessment on my hot wallet first? It's 7 days old, holds 200 USDC, the payee identity is unknown, and I'm signing with EIP-712.”
New wallet pre-payment due diligence
“I just provisioned a fresh agent wallet yesterday with 25 USDC and want to wire it to a per-request x402 endpoint run by an unverified operator — give me an exposure score and flag any forgery or quota-drain risks before I authorize the first payment.”
Signing fatigue risk for automated agent
“My automated agent will call an x402 endpoint roughly 25 times per hour using ECDSA request signing — assess the signing fatigue risk and tell me if the exposure score is acceptable before I connect the wallet.”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/agent-wallet-exposure-assessment-for-per-request?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to connect a live hot wallet to an unfamiliar or newly discovered x402 payment endpoint for the first time, especially when the wallet is young, the operator is unverified, or call frequency will be high. Prefer this over generic risk scoring tools when you need x402-specific checks such as signing-fatigue thresholds, payment-request forgery validation, and quota-drain detection rules tailored to per-request micropayment rails.
Side effects
- Missing required wallet age or balance inputs returns a 400 error
- Unrecognized signing method enum causes validation failure
- Expected call frequency not provided prevents signing-fatigue calculation
- Endpoint operator identity absent skips forgery-check portion of assessment
- Payment required (402) if x402 payment header not included in request
