Header + summary for a base block by number (or "latest"): hash, timestamp, tx count, gas used and base fee.

One call, several formats: rendered HTML content and a base64 screenshot (plus optional Markdown and accessibility tree), with the page's status and title.

Long-term rental listings in Da Nang, Vietnam: search by district, property type, bedrooms and monthly price in VND.

Score up to 50 x402 endpoints in a single paid call. Each found result carries the FULL trust report — identical to POST /v1/x402-trust: score, grade, scoreRange, recommendation, confidence breakdown, the component/subscore breakdown, explanations, flags + flagsDetailed, advertised price, and 30-day on-chain stats — not just the scalar verdict. Cache rows older than 15 minutes are recomputed on-demand from the latest stored probes and settlements, so scores typically reflect reality within minutes. No live network re-probe is performed — for a fresh live probe use /v1/x402-trust. Per-request recompute limits apply (time + count); results include `recomputed` and `computed_at` so you can see which rows used cached vs freshly computed scores. Resources not in our observation set return `found:false`; you still pay for the batch AS LONG AS at least one resource is tracked. If NONE of the supplied resources are in our observation set the request is rejected with HTTP 400 `notCharged:true` and you are NOT charged. Duplicates are ignored.

Semantically similar endpoints that currently out-score a given one on the trust score. Each carries score, grade, similarity, advertised price, and endpoint page; same-host siblings and avoid-flagged endpoints are excluded. An empty list means nothing beats the subject.

Raw observation history for one endpoint over 1-90 days: listing and delisting events, price and payTo changes, and probe results with status and latency. Excluded probes (rate limits, unresolved URL templates, our own resolver outages) never count as downtime. probeSummary aggregates the window.
