Shares a payout wallet with 37 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Paid ($0.03 USDC via x402). POST { "query": "...", "category"?: "..." } to get a demand verdict for any physical-product query. Answers are cached 7 days by normalized query; on a cache miss Demandex matches the query against the mined corpus (signals and cards by keyword) and runs one LLM synthesis call. query must be 3..200 chars. Reads the JSON body first, falling back to ?query=. Verdict shape: { query, verdictScore (0-100), demandTemperature (cold|warm|hot), rationale, topEvidence[] (≤5, e…

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
98

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

Latency
100

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
61

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

Activity
0

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 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

This payout wallet is shared: figures cover all 38 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.
