Payment settles via escrow. dry_run=true previews the exact fills/cost without mutating the book. - `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. - `describe_agent`: Fleet-standard self-description. - `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). - `get_purchase`: Fetch a past purchase / offset certificate by id. - `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. - `list_projects`: List all registered restoration projects with their metadata. - `net_position`: Buyer's carbon position: emitted (from agent-compute-ledger) minus retired. carbon_accountable == true when fully offset. - `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. - `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. - `verify_certificate`: Verify an offset certificate: recompute its hash and check the ledger. - `verify_disbursement`: Recompute the disbursement certificate hash chain and confirm whole-book conservation of disbursed proceeds. Any party can audit disbursements. - `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. - `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). - `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.
