Price — The closing price of the asset in USD, aggregated from both centralised and decentralised exchanges. Strictly immutable data points are available in the point-in-time variant of this metric. Data by Glassnode.

Accumulation Trend Score — Accumulation Trend Score is an indicator that reflects the relative size of entities actively accumulating coins on-chain in terms of their BTC holdings. The scale combines the size of an entity's balance (its participation score) with the amount of new coins it has acquired or sold over the last month (its balance change score). Data by Glassnode.

Total Supply Held by Long-Term Holders — The total amount of circulating supply held by long-term holders. Data by Glassnode.

Miner Net Position Change — The 30-day change of the supply held in miner addresses. Data by Glassnode.

Total Transfer Volume to Exchanges — The total amount of coins transferred to exchange addresses. Data by Glassnode.

Realized Loss — Realized Loss is the total USD loss across all moved coins whose price at their last movement was higher than the price at the current movement. Data by Glassnode.

Realized Price — Realized Price is Realized Cap divided by current supply. It represents the volume-weighted average price at which every unit of circulating supply last moved on-chain. Data by Glassnode.

US Spot ETF Balances — The most recent holdings of the leading U.S.-listed spot Crypto ETFs, typically reflecting balances at the end of the previous trading day (T+1).

Data by Glassnode.

Short Term Holder NUPL — Short Term Holder NUPL (STH-NUPL) is Net Unrealized Profit/Loss computed on UTXOs younger than 155 days, serving as an indicator of the behaviour of short-term investors. Data by Glassnode.

Assets Metadata — Lists all assets known to Glassnode and their metadata, including symbol, name, type, supported blockchains, external IDs, and semantic tags. Use the optional CEL filter to narrow results. Data by Glassnode.

US Spot ETF Flows — An estimate of the daily net fund flow of the leading U.S.-listed spot Crypto ETFs, reflecting day-to-day changes in each ETF's holdings. Covers major Bitcoin ETFs (e.g. IBIT, GBTC, FBTC, ARKB, BITB) and Ethereum ETFs (e.g. ETHA, ETHE, FETH, ETHV, QETH) from issuers such as BlackRock, Grayscale, Fidelity, Bitwise, and VanEck. Data by Glassnode.

Total Supply in Profit — The circulating supply in profit, i.e. the amount of coins whose price at the time they last moved was lower than the current price. Data by Glassnode.

Total Supply in Loss — The circulating supply in loss, i.e. the amount of coins whose price at the time they last moved was higher than the current price. Data by Glassnode.

Circulating Supply — The total amount of all coins ever created or issued, i.e. the circulating supply. Data by Glassnode.

Long Term Holder NUPL — Long Term Holder NUPL (LTH-NUPL) is Net Unrealized Profit/Loss computed on UTXOs with a lifespan of at least 155 days, serving as an indicator of the behaviour of long-term investors. Data by Glassnode.

Balance on Exchanges (Total) — The total amount of coins held on exchange addresses. Data by Glassnode.

Realized Cap — Realized Cap values different parts of the supply at different prices instead of using the current daily close. It represents the aggregate on-chain cost basis of the supply. Data by Glassnode.

Global DeFi snapshot: DeFi market cap (USD), ETH market cap, DeFi-to-ETH ratio, 24h DeFi trading volume, DeFi dominance % of the whole crypto market, and the top DeFi coin with its share of DeFi. The DeFi companion of crypto-global (whole-market caps and BTC/ETH dominance) and of defi-tvl (locked value, a different measure). Cached in-process for 5 minutes. Data provided by CoinGecko.

7 Google Play endpoints. Pay per call in USDC via x402.

Caps individual contributions when requested, computes each project’s raw quadratic match as (sum sqrt(contribution))² minus direct contributions, and allocates a fixed matching pool proportionally. It does not detect Sybil identities, move funds, or decide project eligibility.

One Snapshot proposal plus DETERMINISTIC governance semantics (no LLM): quorum progress and whether quorum is met, the leading choice and its margin, participation (votes and total voting power), seconds remaining, an honest outcome projection (current leader, not a final result), the top voters, and a structured digest.

List a DAO's governance proposals from Snapshot, normalized into one schema: id, title, state, choices, per-choice scores, scores_total, quorum, vote count, start/end, author, snapshot block, strategies and a link-back. Filter by state; pass a Snapshot space-id or a known protocol alias.

A Snapshot space's config and context so an agent understands the voting RULES: name, about, network, token symbol, strategies, admins/moderators, voting delay/period/quorum/type, proposal and follower counts, and a breakdown of active/pending/closed proposals.

Normalized votes on a Snapshot proposal, ordered by voting power: voter address, resolved choice label, voting power, reason and timestamp. Tracks delegate participation and voting behaviour.
