Every change Wellknown observed on this MCP server, newest first, with what it was before and what it became. Tool-surface changes carry the definition diff. Nothing here is edited after the fact.
Changed the definition of "get_listing_kit", "list_indices" and "submit_forecast"
⟨62 unchanged words⟩ 70th and 90th percentiles of the last 30firstpublishedprintsnumbers, two significant digits, equal ones listed once, null under 14 prints), settle_time_utc (whenthethatfirstperiod'sofisthatexpectedperiodtoisbeexpected;published; null for the weekly index, where settle_rule gives the window), settle_rule (the number as first
⟨49 unchanged words⟩ number, unemployment rate, CPI or core CPI was when firstprintedpublished, before the Bureau of Labor Statistics revised it. ⟨249 unchanged words⟩
⟨120 unchanged words⟩ and stay hidden until then. Graded on the number as first
Added "name_a_number" (15 tools before, 16 now)
Name a number — Use when someone wants a number counted that Tickerz does not publish yet, or a market needs a number nobody sells. Send counts (what should be counted, one line, 3 to 160 characters), optionally source_url (where it can be read) and ticker (2 to 12 letters or digits). Tickerz reads the source's terms, then within 48 hours either builds it as a ticker (rule, source, a script that recounts it, the first reading on record) or posts the plain reason it cannot be built, at https://tickerz.com/x. What you send is never shown publicly; the answer is in Tickerz's own words. Returns the count of numb…
Changed the definition of "get_index"
⟨316 unchanged words⟩ and stays null until a proof holds it. forecast is Forecast v1 for the next period: p10, p50 and p90 (an 80% range and its middle), the model the daily run chose, backtest (periods walked forward, coverage_80, skill_vs_last_number: the share of error removed against repeating the last number, negative when worse) and the live record; display only, never a settled number, null when none. Same data as GET /api/indices/{ticker}, plus ⟨12 unchanged words⟩
Added "list_feeds"; changed the definition of "get_report" (14 tools before, 15 now)
⟨75 unchanged words⟩ ://tickerz.com/.well-known/tickerz-signer.json. Same data as GET /api/indices/{ticker}/report. Every signed print with its recount status: https://tickerz.com/signed.
Oracle feeds — Use when a contract, a venue or a person wants every Tickerz oracle feed at once, as on https://oracle.tickerz.com: per index the newest signed value and its period, status (signed, recounted, final, corrected or disputed), how often it is signed, whether a market may settle on it and why, how many reads must agree, the rule version and hash, and its feed account on Solana. live says whether the Solana program is written to yet; before it is, read the signed reports (get_report). Read from a stored copy; read_at says when.
Added "get_report" and "get_rule" (12 tools before, 14 now)
Signed report — Use when a contract, a venue or a person needs the signed Tickerz print for an index: the report (ticker, period, value as a scaled integer with decimals, status provisional, final or corrected, rule version and hash, the provider reads with their snapshot hashes, settleable), its hash, the publisher's Ed25519 signature, the independent recount's co-signatures, and the Solana feed account that holds it. Optional period (YYYY-MM-DD; a month as YYYY-MM-01). How to verify: https://tickerz.com/.well-known/tickerz-signer.json. Same data as GET /api/indices/{ticker}/report.
Index rule — Use when someone needs to know exactly how a Tickerz index is counted before relying on it: the machine-readable rule (source, query, transform, aggregation, cadence, unit, decimals, precision, revision policy, grade, and settlement rights with the terms page and the quoted clause), its version, and its hash (sha256 of the canonical JSON). settleable says whether a market may settle on it: the source's terms allow it and the grade is not display. Same data as GET /api/indices/{ticker}/rule.
