grade evidence: hourly probes of /api/filings/search. Availability, latency and protocol measure the operator's shared infrastructure and generalize across its products; the price check applies to the probed product. We now also probe one other product per hour, rotating; "live price we measured" shows what each answered.
SEC filing search / full-text EDGAR search with AI synthesis — find exactly what companies disclosed on any topic, risk, or keyword across 10-K, 10-Q, 8-K, S-1, and 13F filings, with cited extracts. Filter by form type and date, for research and investing …
What this grade does and doesn't measure: it scores the paid-request handshake — whether the service returns a spec-valid 402 payment challenge, how fast, and whether its price is honest. We do not pay these endpoints yet, so we do not verify that the paid response returns correct or complete content. Availability is a probe success rate measured hourly, corroborated by a second network path for this service.
