Shares a payout wallet with 1 other endpoint — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Evaluate a used car before purchase. Compares the asking price with up to 50 current dealer listings in Canada or the U.S., matched by year, make, model, mileage and optional trim/location. Returns robust median and quartile pricing, deal rating, confidence, sample size and risk flags. Use for used-car price checks, negotiation prep and market comparisons.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
35

How often it was reachable when we probed it (weight 35%).

Latency
99

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
55

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
5

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 34% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 2 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
