Tools

• canon_batch ~338 tokens
  Run up to 50 computes in one call, for scenario grids and sensitivity tables. Each item returns its own receipt; the batch receipt id is sha256 over the sorted item receipt ids, so a whole table can be cited by one hash.
• canon_changes ~104 tokens
  Aggregated dated change events across every vertical, newest first. Poll this instead of re-crawling.
• canon_cite ~180 tokens
  Ready-to-paste citation strings (markdown, plain, apa, bibtex) for one entry, with the reviewed date. Use when writing a report that quotes the canon.
• canon_compute ~340 tokens
  Run one formula from the registry on validated inputs. Returns outputs, the convention used, citations, and a receipt whose id is sha256 over formula, version, canonical inputs and outputs. Invalid inputs return an explicit problem list and a working example instead of nulls.
• canon_contract ~152 tokens
  Fetch one Kalshi (ticker) or Polymarket (slug or condition id) contract and return rules text, close time, resolution source and status in one shape. For a paid cross-venue identity check with a snapshot receipt, call GET /v1/contracts/compare over REST.
• canon_describe_formula ~251 tokens
  Input schema with ranges and defaults, output names, stated convention, citations and test vectors for one formula.
• canon_entity ~142 tokens
  Map a ticker (AAPL, BRK.B), a CIK, or a company name to one issuer id with every ticker and exchange, plus EDGAR filing locations. Use before joining prices, filings and news so identifiers line up; source is the SEC public ticker file.
• canon_get_entry ~160 tokens
  Full definition and notes for one entry, by site and id (ids come from canon_search).
• canon_list_formulas ~78 tokens
  The deterministic formula registry: id, site, summary, input names and citations. Call canon_describe_formula for a schema.
• canon_search ~226 tokens
  Search defined terms and reference tables across all canon sites (options, fixed income, quants, PE, M&A, private credit, venture, hedge funds). Returns ranked hits with a citable url and the JSON source.
• canon_sites ~62 tokens
  The sites in the .wiki finance canon with live entry counts and review dates.
• canon_thresholds ~170 tokens
  Reference table of the regulatory figures agents get wrong: 13F, 13D and 13G, Form 4, Form PF tiers, adviser registration, 3(c)(1) and 3(c)(7), accredited investor, qualified client, Form D, CFTC 4.13(a)(3), ERISA 25 percent, AIFMD, HSR, Reg T. Each row carries the rule, authority, effective date, p
• canon_verify ~132 tokens
  Recompute a receipt from its inputs and confirm its id and outputs. Use it to check a number another agent or document claims came from this service.
