Onchain & crypto

Validate and normalize an Ethereum or EVM wallet address, distinguish valid, absent, or invalid ERC-55 checksum casing, and identify the zero address without a network request.

Base latest block number + timestamp — a chain-head freshness probe. Pay-per-call via x402.

Run a transaction simulation and EVM safety preflight with gas, destination proxy evidence, and optional token security and allowance checks in one decision-ready report.

Trending DEX pools right now — Base, Ethereum, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, or network=all for cross-chain across those same 8. Top 10 hottest pools ranked by GeckoTerminal 24h trending: pool address, DEX, price USD, 24h price change, 24h volume, liquidity (TVL), FDV, 24h txns as flat JSON numbers. Trending pools, hot pools, top movers, momentum screener, what is pumping. $0.001 per call.

Use when a Solana-side agent needs a cheap operational context check at the start of a run or task, as often as it likes. Returns the current UTC time (ISO and unix) plus the latest x402 Bazaar pulse (resource, seller and 30-day call totals, top services, networks) with source evidence and whether this paying wallet has called before. $0.005 per call via MPP on Tempo, x402 on Solana or x402 on Base; no accounts.

Compress long documents and RAG inputs into token-budgeted, deduplicated context packs with source-linked provenance. Returns original and compiled token counts, so the saving is verifiable. Net-positive above N = fee / (r x p) tokens: r your reduction, p your input price. Extractive and budget-bound, so check includedPassages before relying on it. Ranks Latin, Cyrillic, Greek, Arabic and CJK; CJK coarser (bigrams). Not for tabular or heavily-structured payloads.

Net Unrealized Profit/Loss (NUPL) — Net Unrealized Profit/Loss (NUPL) is the difference between Relative Unrealized Profit and Relative Unrealized Loss. Data by Glassnode.

Detailed TVL + breakdown for a single protocol. Pass slug as `/v1/defillama/protocol/{slug}` (e.g. `aave`, `uniswap`).

Everything Agent402 knows about one x402 seller origin, in one read: identity and crawl history, the catalog with the provenance of every price (live-402 or manifest, when it was read, whether it is stale or disagrees with the seller's own declaration), advertised wallets against the wallets that were actually paid (own chain evidence, inherited wallets, shared claims), settlement evidence per source (our Base leaderboard, the x402 Bazaar discovery index, Solana SPL credits, MPP transfers), the.

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

Total Supply Held by Short-Term Holders — The total circulating supply held by short-term holders. 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.

Detailed TVL + breakdown for a single protocol. Pass slug as `/v1/defillama/protocol/{slug}` (e.g. `aave`, `uniswap`).

Coin Days Destroyed (CDD) — Coin Days Destroyed (CDD) measures the volume-weighted age of coins spent on a given day. Data by Glassnode.

Puell Multiple — Puell Multiple is the ratio of the daily issuance value of bitcoins (in USD) to the 365-day moving average of daily issuance value. Data by Glassnode.

Detailed TVL + breakdown for a single protocol. Pass slug as `/v1/defillama/protocol/{slug}` (e.g. `aave`, `uniswap`).

Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.

Everything about a cryptocurrency in one call: live price, 90-day history, trending status, global market context, news search, and top article extraction. Crypto dossier skill pack: one x402 payment runs 6 underlying tools (crypto-price, crypto-history, crypto-trending, crypto-global, search, extract); partial-success per step.

Your own purchase history, keyed to the wallet that pays for the call - no wallet parameter, no signup: the x402 payment IS the identity, so nobody can read another wallet's profile. Returns totals, per-tool counts, per-chain breakdown, recent receipts with settle tx hashes (independently verifiable on-chain), and this wallet's refunds: any payment that settled for a call that failed to deliver, with its status and our refund transaction once sent.

Long Term Holder MVRV — Long Term Holder MVRV (LTH-MVRV) is the MVRV ratio computed using only UTXOs with a lifespan of at least 155 days, serving as an indicator of long-term investor behaviour. Data by Glassnode.

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

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.

Top-holder concentration for a Solana token mint: the 20 largest holders with token account, owner wallet, balance, percent of supply, insider flag and a pool/locker label when the account is a known AMM vault or locker, plus top-1/5/10/20 share, top-10 share excluding labelled pool accounts, insider count, total holder count and supply. Use it to tell a whale-held launch from one whose largest holder is the liquidity pool.

Investor Capitalization — Investor Capitalization is the difference between Realized Cap and Thermocap, discounting the capital paid to miners from the market's general cost basis and serving as a bottom indicator in bear cycles. Data by Glassnode.

Percent Supply in Profit — The percentage of circulating supply in profit, meaning the share of existing coins whose price at the time they last moved was lower than the current price. Data by Glassnode.

Plexa /v1/quote — executable swap quote: the realizable fill price at your trade size, not a mid/spot price feed. Returns price impact (bps), worst-case slippage, depth and the per-leg route across Base/Polygon/Arbitrum liquidity, from canonical on-chain quoters. Call it before a swap to see what the fill actually costs. Informational data, not financial advice.

Solana mint risk preflight via x402: holder-concentration proxy, creator context when covered, coverage and freshness. Use for one mint before launch-dossier spend. Not a rug verdict, price feed, or Birdeye/Nansen substitute. Evidence only — beta.
