dVeracity Semantic API
Registry code: e946a1fb57347558
Check sustainability data before you rely on it. Validate emissions records against the Open Footprint standard, evaluate EU CBAM records and declarations against approved regulatory policies, map ERP and supplier fields onto Open Footprint, and query verified oil-and-gas emissions data (PPDM, OGMP 2.0 methane). Model lookups are free; validation and queries cost 1 credit ($0.01). Every result lists which checks ran and which did not.

- Is dVeracity Semantic API live?
- Yes — it answered the hub's last check (checked 19h ago). It answered 100% of checks over the last 30 days.
- Is dVeracity Semantic API free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does dVeracity Semantic API have?
- 18 tools: semantic_templates, ofp_validate, list_standards, ofp_sector, ofp_semantics, credits_balance, ofp_policies, ofp_search_entities, ….
- Is dVeracity Semantic API safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
semantic_templates reads auth-required never probed
List the query templates the semantic layer supports (free). Cost: free.
ofp_validate reads auth-required never probed
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.
list_standards reads auth-required never probed
List the sustainability data standards dVeracity can validate against (free). Cost: free.
ofp_sector reads auth-required never probed
Get one sector in full (free): its classification, status, reference artifacts and nested industries. Cost: free.
ofp_semantics reads auth-required never probed
List the O-DEF semantic codes carried by the canonical model (free). Cost: free.
credits_balance reads auth-required never probed
Show the remaining dVeracity API credit balance for this account (free). Cost: free.
ofp_policies reads auth-required never probed
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.
ofp_search_entities reads auth-required never probed
Search the 239 canonical Open Footprint entities by concept (free). Cost: free.
ofp_sectors reads auth-required never probed
List industry sectors and their reference implementations (free). Cost: free.
ofp_model_provenance reads auth-required never probed
Show which snapshot of the Open Footprint standard this deployment serves (free): source commit, date, and entity/sector counts. Cost: free.
validate_data reads auth-required never probed
Validate a data payload against a supported sustainability standard (Validation-as-a-Service). Cost: metered per credit.
keri_identity reads auth-required never probed
Show this agent's verified vLEI identity (agent AID, Legal Entity LEI, authorized scopes) if KERI mode is configured — free. Cost: free.
ofp_models reads auth-required never probed
List the eight Open Footprint canonical model domains and which database dialects have published DDL (free). Cost: free.
ofp_entity reads auth-required never probed
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.
compliance_policies reads auth-required never probed
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).
compliance_policy reads auth-required never probed
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).
ofp_semantic_code reads auth-required never probed
Show which canonical fields carry one O-DEF semantic code (free). Cost: free.
semantic_query reads auth-required never probed
Ask a natural-language question about verified emissions data (Open Footprint / PPDM / OGMP-methane knowledge graphs). Cost: metered per credit.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's ide946a1fb57347558.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/e946a1fb57347558/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
