Synapse Discovery: institutional US financial data — point-in-time and survivorship-free throughout. DATA: (1) Equities — daily OHLCV for the full US universe INCLUDING delisted/dead tickers (no survivorship bias), splits/dividends, quality flags. (2) Fundamentals — SEC as-reported statements (income/balance/cash-flow, quarterly+annual, deep history), point-in-time as filed. (3) Funds — ETFs + mutual funds: deep NAV history, FULL point-in-time holdings from SEC N-PORT (pass as_of; not a top-10 snapshot), sector allocations, SEC-sourced fees/AUM, computed ratings, categories and style boxes. (4) Macro — 200+ curated series sourced directly from the primary public publishers (Treasury, Fed releases, BLS, BEA, EIA; served under familiar codes like DGS10/CPIAUCSL — not the FRED API), with point-in-time vintages for major series, plus Treasury yield curves and market context. Any BLS series ID is also fetchable directly. (5) Insiders — SEC Forms 3/4/5 transactions + current beneficial ownership (person-centric across issuers, Rule 10b5-1-aware, amendments resolved, 2021-present) with an HQ-metro prospecting screener; Quant tier. (6) Earnings & estimates — reported-quarter EPS actual vs the consensus at the report (quarterly, as-reported basis, ~2004-present) and daily consensus snapshots captured from 2026-02-19 only (two floors, never conflated — read the tool descriptions); Quant tier. SEMANTICS: pass as_of=YYYY-MM-DD for backtest-safe point-in-time views (holdings, fundamentals, macro vintages). Ratios/weights are FRACTIONS (0.0045 = 0.45%); price and NAV series return oldest-first. Classifications named synapse_* (category, style_box, star_rating, sector) are computed in-house from SEC data — they are NOT an industry-standard classification. Fields we cannot source are null, never guessed. WORKFLOW: tools/list to discover tools. resolve_symbol for fuzzy name->ticker; screen_funds / compare_companies for cross-sectional work; search_economic_series("keywords") to find macro series by concept; get_insider_transactions / get_insider_ownership / screen_insiders for insider work; get_earnings_history / get_earnings_estimates for EPS actual-vs-consensus and estimate history; get_economic_series_batch for many at once; get_quota for remaining budget; submit_feedback to report data gaps or request datasets — it is read and acted on. COST: each tools/call spends 1 unit of your daily quota; every result carries a _quota field (used_today/daily_limit/remaining) so you can self-throttle without extra calls. You are connected on the anonymous free tier — resend the Mcp-Session-Id header on every request. To upgrade, call request_email_verification(email): the ONE human-in-the-loop step is that a HUMAN must read the emailed 8-digit code back to you. On success you get a durable API key in-band (shown once) — save it and reconnect with the X-API-Key header. Paid plans: send your X-API-Key directly.
