More from Orcpin & similar services
Orcpin · Endpoint Reliability
orcpin.dev
x402 endpoint reliability pre-flight: factual service-delivery measurements of a target x402 endpoint before an agent pays it — reachability/uptime rate, valid-402 rate, response latency (p50/p95/p99), last status, and sampled paid delivery verification. Facts only (no trust score, no 'scam' label). Check whether an endpoint is live and delivers before spending on it.
Orcpin · Wash Sale Status
orcpin.dev
Wash-sale preflight for trading agents: evaluates a proposed buy against the operator's realized-loss sales across ALL accounts (caller-supplied) for the 61-day IRC §1091 window — would_trigger with the matched loss sales, an honest clear, or insufficient_data naming the gap. Tax status with the rule cited, never advisability; a disallowed loss defers, not forfeits. Exact-ticker v1; nothing stored. Agent account silos can't see the cross-account window — this check can.
Orcpin · Settlement Date
orcpin.dev
Single-trade T+1 settlement date, as a one-line GET: given a trade date and an as-of date, returns the settlement date and whether it has settled, on the versioned NYSE holiday calendar with SEC Rule 15c6-1 cited. The low-integration sibling of the batch settlement-dates route — no request body. A dates fact, never a violation determination. Nothing is stored.
