Token Unlocks & Vesting API

When locked crypto tokens vest into circulation, who they go to, and how much supply is still to come — live from DeFiLlama's open emissions dataset, no key. A token's price tells you what it costs today; its unlock schedule tells you the supply pressure ahead, the single biggest and most predictable overhang in crypto. When a large tranche of insider, private-sale or team tokens vests, it is fresh sell-side supply hitting a fixed amount of demand — and these dates are known in advance. A static "percent unlocked" number (which dilution APIs give) is only a snapshot; what a trader needs is the calendar: when is the next cliff, how many tokens, what share of total supply, and to whom. The protocols endpoint lists every token DeFiLlama tracks a schedule for (searchable). The next endpoint is the trading signal — the next upcoming cliff unlock for a token: its date, days away, token amount, the share of total supply it dilutes, the unlock type and the recipients (insiders, private sale, team, ecosystem), plus the unlocks after it. The schedule endpoint returns the fuller picture: total and max supply, the allocation by category with how much of each is already unlocked, the count of past and future events, the tokens still locked, and the upcoming events. The token-unlock / vesting-schedule cut — distinct from the tokenomics-and-dilution APIs (which give the static supply and FDV snapshot, not the dated unlock calendar) and from price and market-cap APIs. Amounts are in tokens and as a share of total supply; pair with any price API for the dollar value.

Greenhouse Gas Emissions API

Independent greenhouse-gas emissions data as an API — powered by Climate TRACE, the coalition (backed by Al Gore) that monitors global emissions from satellites, sensors and AI rather than self-reported figures. Get any country's emissions for a given year — CO2, methane (CH4) and nitrous oxide (N2O) in tonnes, plus CO2-equivalent over 100- and 20-year horizons — together with the country's global emissions rank and its share of total world emissions; pass several countries at once to compare them side by side. List the full set of sectors, subsectors and gases that Climate TRACE tracks (power, transportation, manufacturing, agriculture, fossil-fuel operations, waste and more). From China and the United States to any nation on Earth, with data from 2015 onward, it is ideal for climate, ESG, sustainability, policy, journalism and research applications. An independent emissions-inventory data source — distinct from electricity-grid carbon intensity, activity footprint calculators and climate classification. Open data from Climate TRACE (CC BY 4.0).

FuelEconomy.gov API

Official US vehicle fuel-economy data as an API, powered by FuelEconomy.gov — the joint US EPA and Department of Energy resource behind the fuel-economy window sticker on every car, SUV and truck sold in the United States since 1984. Browse the catalogue step by step — model years, then makes, then models, then the engine/transmission trims (each carrying the vehicle id you need for the detail call) — and pull a vehicle's complete fuel-economy record: city, highway and combined MPG, fuel type, engine (number of cylinders and displacement), transmission, EPA vehicle class and drivetrain, the estimated annual fuel cost, tailpipe CO2 emissions in grams per mile, the barrels of petroleum consumed per year and the estimated five-year fuel-cost saving (or extra spend) versus an average new vehicle. Ideal for car-shopping and comparison tools, total-cost-of-ownership and emissions calculators, fleet management and sustainability reporting. The data is authoritative, official EPA/DOE test data and is public domain; it covers US-market light-duty vehicles. Vehicle ids come from the trims endpoint, reached via the year -> make -> model -> trim chain.

Carbon Footprint API

Estimate CO2e emissions for everyday activities using the official DEFRA 2023 GHG conversion factors: road and rail travel (per kilometre by vehicle type, split across passengers), flights (by airport IATA pair with great-circle distance, or by distance, across cabin classes and round trips), grid electricity (by kilowatt-hour and country carbon intensity) and direct fuel combustion (by litres and fuel type). A factors endpoint exposes every emission factor, supported vehicle and fuel type, and the country grid-intensity table. Each result returns CO2e in kilograms, tonnes and grams. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side compute (no third-party upstream), so responses are instant and always available. Ideal for travel and booking flows, sustainability dashboards, ESG and Scope-3 reporting, and carbon-aware product features.
