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. params: issuer*, project_id*, mass_g*, price_minor_per_kg*, verification_ref*, registry, vcs_project_id, vintage, serial_number, methodology |
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. params: credit_id*, reason* |
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. params: none |
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). params: purchase_id*, retirement_reason |
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. params: buyer*, purchase_id*, mass_g*, dry_run |
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. params: buyer*, purchase_id*, budget_minor*, dry_run |
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. params: buyer*, since |
net_position | Buyer's carbon position: emitted (from agent-compute-ledger) minus
retired. carbon_accountable == true when fully offset. params: buyer*, emitted_g* |
verify_certificate | Verify an offset certificate: recompute its hash and check the ledger. params: certificate* |
book | The full credit book with per-credit and book-wide mass conservation totals. params: none |
get_purchase | Fetch a past purchase / offset certificate by id. params: purchase_id* |
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. params: purchase_id*, required_g |
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. params: project_id*, verification_ref*, name, location, methodology, beneficiary, registry_ref |
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. params: project_id |
list_projects | List all registered restoration projects with their metadata. params: none |
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). params: project_id |
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. params: batch_id* |
verify_disbursement | Recompute the disbursement certificate hash chain and confirm whole-book
conservation of disbursed proceeds. Any party can audit disbursements. params: none |
describe_agent | Fleet-standard self-description. params: none |
