x402 Delivery Scores

The AgentPay Prober pays x402 services with real USDC and scores whether they actually deliver. Usage stats say what's popular — paying says what works.

Early data, growing fast: the Prober sweeps the marketplace every Monday & Thursday. Unprobed services rank neutral (factor 1.00) — absence of data never penalizes anyone. These scores feed verified_route ranking directly.

AgentPay's own tools

Excluded from probing by design — a trust oracle must not score itself. Our delivery evidence is the harder kind: real customers' paid calls, each with an on-chain receipt on the receipt ledger.

AgentPay's own tools are deliberately excluded — a trust oracle must not score itself (they're health-checked independently via x402scout). · Raw JSON: /scores.json · Methodology: paid probes over a 30-day window; delivered = payment settled ∧ HTTP 200 ∧ non-empty response ∧ advertised schema matched. Factor: ≥90% → 1.15 boost · 50–90% → sliding · <50% → 0.25 · took-payment-without-delivering → flagged, never recommended. Negative flags are backed by on-chain tx evidence. · Receipt ledger · About AgentPay
