How this service works
Pay-per-call data settled in USDC on Base. No account, no API key, no human in the loop. Measured 2026-10-05: p50 89-105 ms end-to-end over the public internet; our own handling cost is reported per response in the X-Kenward-Serve-Ms header. Safe by construction: the server holds no private key (/health reports holds_keys=false), a signed payment is delivered once, and an unmeasured market answers UNKNOWN instead of a guess. Launch price: 0.025 USD (50% off 0.05) for the first 100 unique paying wallets (excluding the operator's own wallet).
Output
Returns a JSON object containing the marketplace ID, a snapshot date (as_of), a verdict object with a label (e.g. NEVER_PAID) and an explanatory note, the boundary of the data (snapshot-derived), and a coverage percentage indicating how complete the analysis is.
Example use cases
Vetting a marketplace before onboarding
“Before I sign up as a seller on dealwork, can you check if that marketplace has any confirmed payment history or if it's never actually paid anyone?”
Due diligence for a marketplace integration
“We're considering integrating with a third-party marketplace called dealwork — can you pull their payability verdict so I know if real transactions have been observed on their platform?”
Fraud risk check on an unfamiliar platform
“I found a marketplace ID 'dealwork' mentioned in a contract — can you verify whether this marketplace has a legitimate payment record or if it's flagged as never having paid?”
Technical details
Endpoint
GEThttps://pay.kenwardai.my.id/v1/payability?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-use payability verdict on a specific marketplace without setting up an account or API key. It is ideal for one-off due diligence checks, automated trust-scoring pipelines, or fraud risk assessments where you need a snapshot-based answer about whether a marketplace has observed real payment activity. Prefer this over manual research or heavyweight data providers when cost-per-query efficiency and no-registration access matter.
Side effects
- Missing or invalid 'market' query parameter may return an error or empty result
- Unknown marketplace IDs may return a verdict with limited coverage or no data
- Stale snapshot data if the marketplace was recently active — boundary field clarifies this
- Payment failure (402) if the x402 micropayment is not correctly sent or USDC balance is insufficient
