ghg-ledger
Start here: Regulatory Radar — one bounded x402 compliance scan on Base.
What it can do
- Calculate Inventory: Calculate an auditable GHG inventory from explicit activity records. Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual Scope 2 reporting, indeterminate lin
- Classify Activity: Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion.
- List Factor Packs: List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage.

Start here: Regulatory Radar — one bounded x402 compliance scan on Base. List price: $0.25. Inspect the live unpaid quote before signing; the quote is authoritative for this buyer.
Other live carbon + compliance routes: • quantity-takeoff — $0.50 • ghg-ledger — $1.00 • disclosure-compiler — $2.00 • taxcredit-engine — $2.00 • regulatory-radar — $0.25 • regulatory-radar — $0.25 • hive — $5.00 • security-preflight — $1.00
No signup or API key. A caller receives HTTP 402, settles Base USDC, and gets the deterministic result. Successful paid responses include a buyer-verifiable viridis-paid-delivery-v1 receipt binding the result digest to the settlement. Buyer acceptance and usefulness remain unobserved. First paid call from a new wallet is $0.01. Live external proof: 4 settlement(s) from 4 distinct payer(s). Returning buyer? Put your public signing address in X402-Payer-Address on the unpaid preflight to receive the exact returning-wallet quote the first time. The hint never authorizes payment—never send a private key.

Server tool list (6)
Raw names from tools/list. Only developers need these.
| calculate_inventory | Calculate an auditable GHG inventory from explicit activity records. Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual Scope 2 reporting, indeterminate lines, factor lineage, notary payload, and an offset-clearinghouse dry-run weave. This is calculation, not advice. |
| classify_activity | Suggest scope and Scope 3 category from the bundled deterministic map. No inference is used; unknown activity types return no suggestion. |
| list_factor_packs | List the bundled pack version/digest, supported regions and years, activity types, GWP set, and explicit MVP coverage. |
| get_factor_pack | Return factors, GWP values, conversions, sources, and pack SHA for one exact bundled region/year. No nearest-region or nearest-year substitution. |
| verify_result | Recompute a prior inventory's audit hash and conservation checks. Pass the prior result object as JSON; tampering or stale factor lineage is flagged. |
| describe_agent | Return fleet-standard capabilities, version, pack digest, and pricing. |
