Blockchain And Crypto x402 offerings

Crypto trading signal (long/short) and market-regime signal in ONE call: LONG/SHORT/NEUTRAL with confidence, fusing the cross-exchange funding rate, crowding (long/short) bias, trend/chop market regime and BTC→altcoin lead-lag from Binance/Bybit/OKX/Hyperliquid — with declared data freshness. Should I go long or short on this coin? A fused directional trading signal where competitors sell the funding rate, regime and the four numbers separately. Derivatives trading signal for any altcoin.

Convert an amount between the main cryptocurrencies and ECB currencies (0.5 BTC to ETH, 100 USDT to EUR, 1000 EUR to SOL) with alternative.me prices (~190 largest coins) and ECB reference rates.

Current USD prices for any crypto asset: majors by ticker (BTC, ETH, SOL), anything else by CoinGecko id or chain + contract address — so long-tail meme tokens work too. Up to 25 assets per call with per-asset confidence scores and timestamps. Crypto only; no equities or ETFs. POST a JSON body like: {"symbols":["BTC","ETH","pepe"]}

Detect and validate a crypto address before sending funds: EVM (EIP-55 checksum), Solana, Bitcoin (legacy, P2SH, SegWit, Taproot), Litecoin, Dogecoin, Tron and Cosmos bech32, with its type and network. Computed locally.

Crypto address validator: identify which blockchain an address belongs to and validate its encoding: EVM EIP-55 checksum, Bitcoin base58check and bech32/bech32m with witness version, Solana base58 and on-curve check, Cosmos bech32 with its HRP, Tron, XRP, Litecoin, Dogecoin, Cardano, Polkadot SS58 and Algorand. Returns every chain the address is valid for (ambiguous when several match), the checksummed form for EVM addresses, and the reason a check failed, including unrecognised_format.

All 15 Blockchain IQ blockchain network dashboards sold here in a single call (section=networks), each with its activity charts and the analyst's read of every chart: Bitcoin, Ethereum, Solana, XRP Ledger, Base, Polygon, Avalanche, BNB, TON, Tezos and more. No price charts. JSON, no API key. $0.50 per call. Blockchain IQ.

One chart from a Blockchain IQ crypto analytics dashboard, with the analyst's read of that chart: a time series or ranked table with its unit, source view and refresh time. Pick a dashboard slug and a panel slug, e.g. bitcoin-network/active-addresses; an unknown panel returns the dashboard's panel list and is not charged. Covers per-chain activity on 15 blockchains and DeFi lending rates; price charts are not sold. JSON, no API key. $0.03 per call. Blockchain IQ.

Blockchain IQ analytics with an analyst read on each chart: 16 dashboards, 15 blockchain networks from Bitcoin to Solana (activity, fees, block space, active addresses; no price charts) plus defi-lending-rates (Aave v3 and Morpho rates read from the contracts). Pick one by slug; the live slugs are enumerated in the catalogue and OpenAPI schema, e.g. bitcoin-network, solana-network, xrp-ledger. $0.25 per call; defi-lending-rates is $0.10. Blockchain IQ.

Crypto and tokenized stock market signals, live: every covered asset ranked by trade-flow signal - buy/sell pressure from the exact taker side of on-chain swaps, momentum, activity and anomaly versus each asset's own baseline, confidence and a signal label. Windows 1m, 5m, 15m. Use for a ranked snapshot of what is moving right now.

Crypto buying pressure ranking: assets under aggressive buying, ranked by buy pressure from the exact taker side of every on-chain swap (arbitrage, MEV and bot trades excluded), plus volume, imbalance and price change. Use to find what buyers are chasing.

Coin categories (Layer 1, Meme, AI, DeFi, Stablecoins, RWA, ...) ranked by market cap, with 24h market cap change %, 24h volume and the top-3 coins per category. Order by market_cap_desc (default), market_cap_asc, market_cap_change_24h_desc/asc, name_asc/desc; optional `query` substring filter on category name/id; limit 1-100 (default 25). The sector-rotation view: which narratives are gaining or bleeding today. Cached in-process for 5 minutes. Data provided by CoinGecko.

Perpetual funding rate and open interest for up to 10 coins in a single call, across Binance, Bybit, OKX and Hyperliquid. Answers 'where is the leverage right now?' for a whole watchlist at once. Thin venues are excluded: averaging every venue that publishes a rate overstates BTC funding by ~30x, because a near-empty book printing 9% per 8h counts the same as a deep one. Funding comes per 8h and annualized, so 0.0067% reads as 7.3% a year.

Bitcoin network health: hashrate, difficulty, transaction count, estimated volume, miner revenue and the largest recent mempool transactions. A congested mempool carrying large transfers can front-run an exchange flow you will only see in price an hour later.

Funding rate and open interest for one coin, broken down venue by venue across Binance, Bybit, OKX and Hyperliquid, using each venue's largest-open-interest perpetual. Use it when venue divergence matters: one venue far more positive or negative than the rest is localised positioning, not market consensus — the setup that precedes a squeeze on that venue alone. Returns per-venue rows plus average funding, total open interest and the spread.

Real-time crypto & macro market data for AI agents, pay-per-call in USDC (no account or API key): Bitcoin (BTC) and Ethereum (ETH) prices, funding rates, open interest, Fear & Greed index, market dominance, macro rates (Fed, CPI, DXY), DeFi TVL, whale flows, on-chain stats, crypto news. 16 JSON tools. POST {tools:[…]} — up to 5 tools in one paid call.

BTC, ETH and USDT dominance as a share of total crypto market cap — the regime filter to check before sizing any altcoin position. Rising BTC dominance means capital rotating to relative safety; rising USDT dominance means capital leaving for stablecoins, a broader risk-off. Falling BTC dominance with rising ETH dominance is the classic rotation signal.

Crypto Fear & Greed Index: current and previous value with classification, plus recent history. A contrarian input — extreme fear has historically marked accumulation zones and extreme greed distribution zones — but it is a filter, never a trigger on its own. Pair it with funding to separate real capitulation from a crowded short.

AI crypto analyst, pay-per-call in USDC: ask any question on Bitcoin, Ethereum, altcoins or macro; the agent picks live market data tools (prices, funding rates, open interest, Fear & Greed, macro rates), runs them and returns one JSON object: regime, confidence, key_data with the numbers behind it, bull and bear scenarios, invalidation_level, summary. POST {question}.

Large ETH transfers (>100 ETH) to and from known exchange wallets in the last 2 hours. Inflows to exchanges are potential distribution pressure, outflows suggest accumulation or a move to cold storage — but read them as context, not instruction: a single large transfer is often internal rotation between wallets of the same desk.

Recent crypto headlines for narrative context and catalysts — the qualitative layer that explains why funding moved when no macro print did. Returns headlines with attribution for summarisation, not article text.

Total value locked across DeFi, the top chains by TVL, and aggregate stablecoin market cap. Stablecoin supply is the dry powder of the whole market: rising supply with rising TVL is risk appetite expanding, falling supply is capital genuinely leaving crypto rather than rotating inside it.

Whether the current reading is actually high or low, from a series captured every ~10 minutes: funding, open interest, Fear & Greed and BTC dominance, each as current, median, min, max and percentile over the window. A funding rate of 0.006% means nothing on its own; at the 89th percentile of the last 24 hours it means something. This is the question a snapshot endpoint cannot answer, whoever you buy it from.

Ethereum address activity: ETH balance plus recent large transfers in and out. Point it at an exchange wallet, a treasury or a wallet a headline just named, and get the movement behind the story rather than the story.

Spot price, market cap, 24h volume and 24h change for any coins by id (bitcoin, ethereum, solana and thousands more), in any quote currency. The reference leg for every other signal here: funding and open interest only mean something next to what price did.
