How this service works

Pay-per-call data & tool APIs

Output

Returns a structured JSON object containing: the compliance rule applied (status, phase-in, ETS gases, rule version, reporting year, surrender year and deadline, accepted-through year, digest hashes), the result decision and status, confidence level with reasons, data quality assessment (completeness, truth mix, partial flag), a truth ledger with verified inputs and coverage status, and input identity digests for the vessel and voyage. Also includes run time and settlement confirmation in the meta block.

Example use cases

ETS Surrender Obligation Check

“I need to know if vessel o_7dc546b848eaf85258d7499ca99efc71bc5a7627c53a658b1804 has any carbon allowance surrender obligations for its recent voyage — can you pull the compliance evidence including the surrender deadline and which ETS gases apply?”

Automated Voyage Compliance Audit

“For our fleet audit, check the carbon compliance status on voyage o_5fa3c19b50d19b9f4931b99862f51cd2cecf25ee664ffc45220a and return the rule version, reporting year, and whether the data quality is complete enough to make a decision.”

Carbon Regulatory Evidence for Port Authority

“We need to present compliance evidence to the port authority showing that this voyage met carbon reporting requirements — can you retrieve the truth ledger and verification status for voyage o_5fa3c19b50d19b9f4931b99862f51cd2cecf25ee664ffc45220a on vessel o_7dc546b848eaf85258d7499ca99efc71bc5a7627c53a658b1804?”

Technical details

Endpoint

When to prefer

Use this endpoint when you need cryptographically-anchored, pay-per-call compliance evidence for a specific maritime voyage under carbon/ETS regulations, particularly when you need verifiable digests (vessel identity, voyage identity, input contract) for audit trails. Prefer this over generic emissions databases when you require structured rule versioning, surrender deadlines, and truth ledger entries that can be presented as regulatory evidence.

Side effects

Unknown or invalid vessel/voyage identity — returns result with status 'not_available' and no decision
Demo mode response when no real decision data exists — returns synthetic_demo_no_decision status
Confidence level 'not_assessed' when MRV verification has not been performed
Payment failure via x402 protocol — call not executed
Malformed request digest or contract digest — may return error or unresolvable identity
