Measured tools (6)

• calculate_inventory

  Calculate an auditable GHG inventory from explicit activity records. Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual Scope 2 reporting, indeterminate lines, factor lineage, notary payload, and an offset-clearinghouse dry-run weave. This is calculation, not advice. Price: $1.00 per call after 10 free calls/day. Pay at /x402/ghg-ledger/calculate_inventory with Base USDC, cash-fund payment_ref through escrow_checkout + confirm_escrow_funding, or use /seats.

  Parameters:

  • activities (required) — array
  • options
  • request_id
  • payment_ref

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

• classify_activity

  Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.

  Parameters:

  • activity (required) — object

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

• list_factor_packs

  List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.

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

• get_factor_pack

  Return factors, GWP values, conversions, sources, and pack SHA for one exact bundled region/year. No nearest-region or nearest-year substitution.

  Parameters:

  • region (required) — string
  • year (required) — integer

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

• verify_result

  Recompute a prior inventory's audit hash and conservation checks. Pass the prior result object as JSON; tampering or stale factor lineage is flagged.

  Parameters:

  • result_json (required) — string

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

• describe_agent

  Return fleet-standard capabilities, version, pack digest, and pricing.

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