dVeracity Semantic API

Verified emissions data and the Open Footprint canonical model, for agents. Eighteen read-only tools over MCP (remote Streamable HTTP with OAuth 2.1, or the stdio npm package): natural-language queries over a verified emissions knowledge graph (metered), the Open Footprint model — entities, sectors, O-DEF semantics, sector guardrails (free) — validation of payloads against the model and published guardrails (metered), and approved regulatory compliance policies (paid plans). Credit-billed with machine-readable HTTP 402 semantics; optional vLEI-verified agent identity (GLEIF-rooted Agent Authorization credentials).

Skills

• semantic_query
  Ask a natural-language question about verified emissions data (Open Footprint / PPDM / OGMP-methane knowledge graphs). Cost: metered per credit.
  meteredread-only
• semantic_templates
  List the query templates the semantic layer supports (free). Cost: free.
  freeread-only
• credits_balance
  Show the remaining dVeracity API credit balance for this account (free). Cost: free.
  freeread-only
• list_standards
  List the sustainability data standards dVeracity can validate against (free). Cost: free.
  freeread-only
• validate_data
  Validate a data payload against a supported sustainability standard (Validation-as-a-Service). Cost: metered per credit.
  meteredread-only
• keri_identity
  Show this agent's verified vLEI identity (agent AID, Legal Entity LEI, authorized scopes) if KERI mode is configured — free. Cost: free.
  freeread-only
• ofp_models
  List the eight Open Footprint canonical model domains and which database dialects have published DDL (free). Cost: free.
  freeread-only
• ofp_search_entities
  Search the 239 canonical Open Footprint entities by concept (free). Cost: free.
  freeread-only
• ofp_entity
  Get one canonical entity in full (free): fields with types and required flags, primary key, relationships, and the physical database table implementing it. Cost: free.
  freeread-only
• ofp_sectors
  List industry sectors and their reference implementations (free). Cost: free.
  freeread-only
• ofp_sector
  Get one sector in full (free): its classification, status, reference artifacts and nested industries. Cost: free.
  freeread-only
• ofp_policies
  Get a sector's policy guardrails as Rego source (free), with policies[].inputs listing the record types and input fields each policy reads — e-ledger fields such as co2e_kg and direction, not canonical Open Footprint fie Cost: free.
  freeread-only
• compliance_policies
  List APPROVED regulatory compliance policies — rules AI-extracted from a regulation (for example EU Green Bonds, CSRD/ESRS) and approved by a dVeracity admin. Cost: paid plans (VaaS and above).
  paidread-only
• compliance_policy
  One APPROVED regulatory compliance policy in full: its Rego source, the structured rules the extractor produced, the record types and input fields the Rego reads, and provenance (source regulation document, extraction mo Cost: paid plans (VaaS and above).
  paidread-only
• ofp_validate
  Check a data payload against the canonical Open Footprint model and, when a sector is named, that sector's published Rego guardrails. Cost: metered per credit.
  meteredread-only
• ofp_semantics
  List the O-DEF semantic codes carried by the canonical model (free). Cost: free.
  freeread-only
• ofp_semantic_code
  Show which canonical fields carry one O-DEF semantic code (free). Cost: free.
  freeread-only
• ofp_model_provenance
  Show which snapshot of the Open Footprint standard this deployment serves (free): source commit, date, and entity/sector counts. Cost: free.
