Values you fill in

• DVERACITY_API_KEY secret required env
  dVeracity API key (dvrc_...). Required for the stdio package; metered calls are billed to it. Not used by the remote endpoint, which authenticates with OAuth.
• DVERACITY_API_URL env
  Optional. Override the API base URL; defaults to production.
• DVERACITY_KERI_AID env
  Optional. Agent AID enabling vLEI-verified identity mode.
• DVERACITY_KERI_PRESENTATION env
  Optional. Path to the CESR presentation used with the agent AID.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• semantic_query

  Use this when a user asks a specific question about verified oil-and-gas emissions data, for example methane emissions for a site, company or period (PPDM, OGMP 2.0). Call semantic_templates first to see what the data can answer. Do not use for general climate questions. On payme

• semantic_templates

  Use this when you want to see which kinds of questions the verified emissions data can answer, before calling semantic_query.

• credits_balance

  Deprecated: use billing_status, which also shows plan and free allowance. Removal planned for 0.9.

• list_standards

  Use this when you need to see which sustainability data standards and versions validate_data can check, before calling it.

• validate_data

  Use this when a user wants a payload checked against a standard other than Open Footprint; call list_standards first to see which are supported. For Open Footprint payloads use ofp_validate. Only masterData or referenceData; call list_standards first.

• keri_identity

  Use this when an organisation needs to confirm which verified legal entity and agent identity dVeracity is attributing calls to. Only relevant when vLEI identity is configured.

• ofp_models

  Use this when a user is building an app, database or integration on the Open Footprint standard and needs to know what the model covers. Start here before any other ofp_ tool. The response summary carries the served counts.

• ofp_search_entities

  Use this when you need the Open Footprint entity for a concept such as "Scope 3 emissions", "facility" or "product footprint". Do not use for emission factors or calculations. Matches entity names, descriptions and field names; use ofp_entity for the full definition.

• ofp_entity

  Use this when you need one entity's fields, types, keys and relationships, for example to design a table or an API payload. Pass domain when known: ambiguous names fail rather than guessing (ofp_models reports ambiguousNameCount).

• ofp_sectors

  Use this when a user asks which industries Open Footprint covers or whether a sector has a reference implementation. implemented means a reference implementation exists; planned or placeholder means nothing is published.

• ofp_sector

  Use this when you need one sector's classification, status and reference artifacts.

• ofp_policies

  Use this when a user asks which validation rules apply to a sector's emissions records. Do not use for regulations; use compliance_policies. inputs lists the e-ledger fields each policy reads (e.g. co2e_kg, direction), not canonical Open Footprint names. published:false means no

• compliance_policies

  Use this when a user needs data checked against a regulation, for example EU CBAM, to find the approved policy to run. Do not use for Open Footprint sector rules; use ofp_policies. Returns only APPROVED policies; drafts and rejected never appear. An empty list means none publishe

• compliance_policy

  Use this when you need the full rules, provenance and coverage of one approved regulatory policy. Returns Rego only when the source was retained; otherwise rego_unavailable: source_not_retained. A policy without Rego is not loaded into the engine; enforcement says whether its str

• compliance_evaluate

  Use this when a user wants an import record or an annual EU CBAM declaration (Reg. (EU) 2023/956) checked against an approved policy before filing. Do not use for carbon-footprint calculations or for regulations compliance_policies does not list. Runs the policy's regulation-deri

• compliance_evaluation

  Use this when a user wants to retrieve or audit a previous regulatory evaluation by its id. Only the caller who ran it can read it; another account's id answers not found. Requires compliance:read.

• compliance_policy_register

  Use this when a user asks which provisions of a regulation an evaluation actually checks and which it does not. Shows which provisions are encoded and which are not: a pass on the encoded checks is not compliance with excluded provisions. Requires the compliance:read scope.

• ofp_validate

  Use this when a user wants an emissions or footprint record (JSON) checked against the Open Footprint model or a sector's guardrails before storing, exchanging or reporting it. Do not use for general data-quality questions without a payload. Checks structure, declared constraints

• ofp_semantics

  Use this when mapping fields from SAP, another ERP or a supplier feed onto Open Footprint. A high fieldCount is a generic fallback; pass maxFieldCount (10 is a good start) for codes specific enough to align on.

• ofp_semantic_code

  Use this when you have a source-system field and need to find where it belongs in the Open Footprint model. Codes carried by more than ten fields are generic classifications; aligning to one asserts less than it appears.

• ofp_model_provenance

  Use this when a user asks which version of the Open Footprint standard they are designing against.

• billing_plans

  Use this when you need to know what each dVeracity plan includes or what the free allowance covers. Show dVeracity plans, what each plan includes and the free-tier allowance.

• billing_status

  Use this when a call was refused for credits or plan, to tell the user exactly what is missing. Use it after a 402 to tell your human exactly what is missing.
