How this service works
Decision procedure for agents that must prove real adoption of a service from its x402 payment ledger. Inputs: paid-call history with payer addresses, amounts, timestamps, rail identifiers, and the claim window. Outputs: adoption verdict (proven, partial, unproven) with thresholds: unique-payer floor per week, repeat-purchase rate minimum, self-pay and same-wallet dedup rules, cohort retention across the claim window, and settlement diversity across rails. Failure modes: one-off bulk buys
Output
A JSON object containing an adoption verdict (proven, partial, or unproven), a prose decision procedure brief explaining the reasoning, thresholds applied (unique-payer floor per week, repeat-purchase rate, self-pay/same-wallet dedup, cohort retention, rail diversity), the service slug, generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp.
Example use cases
Validate adoption before x402 marketplace listing
“Before I list this x402 service on the marketplace, can you run the adoption proof procedure on its payment ledger for the past 8 weeks and tell me if it comes back proven, partial, or unproven — including whether any self-pay or same-wallet transactions were deduplicated?”
Investor due diligence on x402 service traction
“I'm evaluating an x402 service that claims strong adoption — can you analyze its paid-call history for the last 6 weeks and check whether the unique-payer floor, repeat-purchase rate, and cohort retention thresholds are actually met, or if the numbers are inflated by bulk buys?”
Agent deciding whether to trust a high-volume payment rail
“I need to know if the x402 payment data for this service shows genuine multi-rail settlement diversity and recurring payers over the past 4 weeks, or if it's mostly one-off bulk purchases — give me an adoption verdict with the breakdown.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-adoption-proof-from-x402-payment-ledgerWhen to prefer
Use this endpoint when you need a structured, rule-based adoption verdict grounded in x402 on-chain payment data rather than self-reported metrics. Prefer it over generic analytics tools when the payment history is denominated in x402 settlements and you need dedup rules specific to agent-pay patterns (self-pay, same-wallet, bulk-buy detection). It is particularly valuable for marketplace listing gatekeeping, investor due diligence, or agent-side trust decisions about a service's real traction.
Side effects
- One-off bulk buys inflate apparent adoption but are deduplicated, potentially flipping verdict from proven to partial or unproven
- Same-wallet or self-pay transactions are flagged and removed, reducing unique-payer count
- Insufficient payment history within the claim window may result in an unproven verdict even for legitimate services
- Missing or incomplete rail identifiers prevent settlement diversity analysis
- Claim window too short to establish cohort retention, leading to inconclusive partial verdict
