book
The full credit book with per-credit and book-wide mass conservation totals.
入力スキーマ

出力スキーマ
{'type': 'object', 'title': 'bookOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
buy_offset
Retire mass_g of verified credits for a buyer: cheapest-first matching,
exactly-once (idempotent on purchase_id), returns a content-addressed
offset certificate with per-fill costs. Payment settles via escrow.
dry_run=true previews the exact fills/cost without mutating the book.
入力スキーマ
{'type': 'object', 'title': 'buy_offsetArguments', 'required': ['buyer', 'purchase_id', 'mass_g'], 'properties': {'buyer': {'type': 'string', 'title': 'Buyer'}, 'mass_g': {'type': 'integer', 'title': 'Mass G'}, 'dry_run': {'type': 'boolean', 'title': 'Dry Run', 'default': False}, 'purchase_id': {'type': 'string', 'title': 'Purchase Id'}}}
出力スキーマ
{'type': 'object', 'title': 'buy_offsetOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
buy_offset_budget
Money-denominated offset purchase: retire the maximum cheapest-first
verified mass whose exact cost fits inside budget_minor (never overspends).
Built for callers whose restoration obligation is a currency amount —
e.g. a revenue share accrued in a ledger. Idempotent on purchase_id;
dry_run=true previews without mutating.

certify_disbursement
Freeze the current disbursement schedule into a certified, tamper-evident
batch (content-addressed, hash-chained). Idempotent on batch_id; only
newly-accrued proceeds for verified projects are certified (never disbursed
twice). This is the certified investment record the CEO executes the actual
Stripe transfers against.

delist_credit
Admin operation: remove a credit from the active fill path while
retaining its listing and retirement history for audit. Idempotent for an
already-delisted credit. Gateway state-change authentication is required.

{'type': 'object', 'title': 'describe_agentOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
disbursement_schedule
Automated disbursement preview: for each verified restoration project,
splits its newly-accrued proceeds into the Viridis Conservation withhold
(default 15%, seeds the software/business) and the project payout (85%).
Read-only. Funded-but-unregistered projects are surfaced separately as
pending_registration (can't pay an unverified project).

出力スキーマ
{'type': 'object', 'title': 'get_purchaseOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
list_credit
List a conservation credit on the book. verification_ref (a D-Score /
land-verification attestation) is REQUIRED — unverified credits cannot
enter the book. To trade on the Verra network, pass registry="verra" with
the VCS provenance (vcs_project_id, serial_number, vintage, methodology) so
retirements are cross-referenceable on registry.verra.org.

出力スキーマ
{'type': 'object', 'title': 'list_projectsOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
net_position
Buyer's carbon position: emitted (from agent-compute-ledger) minus
retired. carbon_accountable == true when fully offset.
入力スキーマ
{'type': 'object', 'title': 'net_positionArguments', 'required': ['buyer', 'emitted_g'], 'properties': {'buyer': {'type': 'string', 'title': 'Buyer'}, 'emitted_g': {'type': 'number', 'title': 'Emitted G'}}}
出力スキーマ
{'type': 'object', 'title': 'net_positionOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
project_funding
Supply-side disbursement ledger: how much each restoration project has
earned from retirements and is owed (gross_proceeds_minor + retired_g).
Pass a project_id for one project, else all. Read-only — the CEO settles
the actual payout. This is what makes the clearinghouse fund restoration.

register_project
Register a VERIFIED restoration project so retirements against its
credits can be funded. verification_ref (D-Score / land-verification /
registry id) is required — only verified conservation is funded.
project_id is immutable once registered.
入力スキーマ
{'type': 'object', 'title': 'register_projectArguments', 'required': ['project_id', 'verification_ref'], 'properties': {'name': {'type': 'string', 'title': 'Name', 'default': ''}, 'location': {'type': 'string', 'title': 'Location', 'default': ''}, 'project_id': {'type': 'string', 'title': 'Project Id'}, 'beneficiary': {'type': 'string', 'title': 'Beneficiary', 'default': ''}, 'methodology': {'type': 'string', 'title': 'Methodology', 'default': ''}, 'registry_ref': {'type': 'string', 'title': 'Registry Ref', 'default': ''}, 'verification_ref': {'type': 'string', 'title': 'Verification Ref'}}}

settlement_batch
Read-only cash-settlement summary for a buyer: the list + exact sums
(purchases, mass_g, cost_minor) of their retirements, optionally since an
ISO-8601 timestamp — the statement a human settles in one transfer.
入力スキーマ

verify_retirement
x402-C C4 check: confirm a retirement (offset_ref = purchase_id)
actually retires at least required_g grams of verified conservation
credit — the check that lets a carbon receipt's neutrality claim be
honored. Returns covered / retired_g / shortfall_g and the backing
credits. Read-only.
入力スキーマ
{'type': 'object', 'title': 'verify_retirementArguments', 'required': ['purchase_id'], 'properties': {'required_g': {'type': 'integer', 'title': 'Required G', 'default': 0}, 'purchase_id': {'type': 'string', 'title': 'Purchase Id'}}}

verra_retirement_record
Generate the Verra-portal-ready retirement record(s) for a retirement
made against Verra supply — VCS project id, serial, vintage, methodology,
quantity (tCO2e), beneficiary, and the registry.verra.org cross-reference.
Read-only. Submit these under the Viridis Verra account to finalize the
on-registry retirement (portal today; auto-posts when Verra's transaction
API is live).
入力スキーマ
{'type': 'object', 'title': 'verra_retirement_recordArguments', 'required': ['purchase_id'], 'properties': {'purchase_id': {'type': 'string', 'title': 'Purchase Id'}, 'retirement_reason': {'type': 'string', 'title': 'Retirement Reason', 'default': ''}}}

verra_supply
The tradeable Verra VCS book: verified credits carrying genuine Verra
provenance (project id + serial + vintage), cross-referenceable on
registry.verra.org. Read-only. Every retirement nets the project 85% and
Viridis the 15% marketplace take.
