Source methodology
MarketPulse uses an explicit registry rather than unrestricted web crawling. Every source has a trust tier, permitted host, cadence and terms record.
Allowlisted collection
The crawler accepts credential-free HTTPS endpoints only, validates redirects and resolved addresses, limits payload size, sanitizes text and honors conditional HTTP headers.
Confidence labels
Official means a government, regulator, filing, issuer or verified project source. Corroborated means at least two independent approved domains. Developing means one approved secondary report. Corrected and Withdrawn show source changes.
Deduplication and clustering
Canonical URL hashes, source identifiers, normalized titles, similarity rules and publication windows combine related reports into one timeline.
Relevance scoring
Fixed term groups score rates, inflation, currency, yields, geopolitics, regulation, ETFs, network security and current US30 constituent fundamentals.
