Measured tools (13)

• canon_sites read-only

  The sites in the .wiki finance canon with live entry counts and review dates.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• canon_search read-only

  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.

  Parameters:

  • q (required) — string — Search phrase, e.g. "modified duration" or "option pool shuffle"
  • site — string — Restrict to one site
  • limit — integer

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• canon_get_entry read-only

  Full definition and notes for one entry, by site and id (ids come from canon_search).

  Parameters:

  • site (required) — string
  • id (required) — string — Entry id or slug, e.g. "modified-duration"

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• canon_changes read-only

  Aggregated dated change events across every vertical, newest first. Poll this instead of re-crawling.

  Parameters:

  • since — string — ISO date; only events on or after this date

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• canon_list_formulas read-only

  The deterministic formula registry: id, site, summary, input names and citations. Call canon_describe_formula for a schema.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• canon_describe_formula read-only

  Input schema with ranges and defaults, output names, stated convention, citations and test vectors for one formula.

  Parameters:

  • formula (required) — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• canon_compute read-only

  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.

  Parameters:

  • formula (required) — string
  • inputs (required) — object — Inputs keyed by name; see canon_describe_formula

  Hints: read-only yes · destructive not declared · idempotent yes · open-world not declared

• canon_verify read-only

  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.

  Parameters:

  • receipt (required) — object — The receipt object returned by canon_compute

  Hints: read-only yes · destructive not declared · idempotent yes · open-world not declared

• canon_batch read-only

  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.

  Parameters:

  • items (required) — array

  Hints: read-only yes · destructive not declared · idempotent yes · open-world not declared

• canon_entity read-only

  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.

  Parameters:

  • q (required) — string
  • limit — integer

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• canon_thresholds read-only

  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, primary source and a confidence label. Filter by words or authority.

  Parameters:

  • q — string
  • authority — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• canon_contract read-only

  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.

  Parameters:

  • venue (required) — string
  • id (required) — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• canon_cite read-only

  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.

  Parameters:

  • site (required) — string
  • id (required) — string
  • format — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes
