Blockchain And Crypto x402 offerings

Hyperliquid vaults, two modes in one route: pass `vault` (an address) for a single vault overview — name, leader, TVL, APR, age, max drawdown, pnl trend and a deterministic 0-100 quality score; or omit it for a ranked discovery list of the top open vaults by `sort` (tvl or apr). public on-chain data, not financial advice.

Read a contract's recent event logs on an EVM network over a bounded block window and decode them. Logs are decoded from an event signature you supply, or from the contract's verified ABI, or by resolving the topic to a name via 4byte. Raw logs are always returned; decoded fields are added where possible.

Crypto Fear & Greed index with a market-timing trend: current value and classification, 7-day and 30-day deltas, streak in the current regime, 30-day min and max, and a contrarian flag on extreme fear or greed. Keyless.

Centralized-exchange (CEX) solvency / proof-of-reserves counterparty-risk verdict in one call: given an exchange name, returns reserve totals, own-token concentration (the FTX/FTT pattern), clean-asset ratio, netflow stress, leverage and a deterministic 0-100 solvency_score with a rating, risk flags and a peer rank. Fused from the keyless DefiLlama CEX Transparency reserve aggregate. Reserves are a PROXY: customer liabilities and PoR-attestation quality are not visible.

Live Bitcoin mempool snapshot: unconfirmed transaction count, total virtual size and total fees, a fee-rate histogram broken into buckets, and an estimated block backlog. Informational, not advice.

Composite crypto market sentiment: the Fear & Greed index (value, classification, trend) blended with aggregated news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.

Non-custodial yield deposit/redeem calldata for Base: give protocol (aave-v3, compound-v3 or erc4626), asset or vault, raw amount, action and recipient; we read the protocol on-chain state and return ready-to-sign transaction calldata plus the ERC-20 approval (deposit only) and the expected shares or assets. You sign with your own wallet — we never hold or move funds.

Flagship NFT collection intelligence: fuses identity, floor (native+USD), market cap, volume, total supply, holders and listed count into COMPUTED metrics — liquidity ratio (listed/supply + volume/mcap), holder/supply ratio, sales velocity and floor momentum — plus a normalized market-health verdict with confidence and rationale. EVM via CoinGecko, Solana + Bitcoin-Ordinals via Magic Eden. Keyless, attributed.

Diagnose why another x402 route does not settle or stays invisible in Bazaar. From the route URL: a verdict (ready / blocked / degraded) plus per-check findings each with a concrete fix, over the CDP settle-blockers (header size, WAF text, method honesty, canonical-USDC, real index membership, on-chain settle fact). Diagnostic indicators, not a guarantee.

ABI-encode a function call (selector + args) or encode/decode arbitrary ABI types — build and parse EVM calldata correctly.

Network health and token-economics verdict for a DePIN network from public data. Give network (helium) and get coverage size (IOT and MOBILE node counts), token supply for HNT, IOT, MOBILE and DC read on-chain, the emission and halving context, and a coverage-scale indicator. Each value is cited to its source.

Aggregated crypto news with sentiment: deduplicated headlines from many major crypto outlets (CoinDesk, Cointelegraph, Decrypt, Bitcoin Magazine, The Block, CryptoSlate), each scored bullish/bearish/neutral by a crypto-tuned lexicon, optionally filtered by coin or query. One call instead of polling a dozen feeds and running your own NLP.

The single next token unlock for one crypto token, cheapest actionable signal. Give a ticker, name or slug and get just the next scheduled unlock (date, token amount, USD value, percent of circulating supply, unlock type) plus the token's recent emission velocity over 24 hours, 7 days, 30 days and one year. Data from DeFiLlama, cited.

Reward economics and earnings trend for a DePIN entity or subnetwork. Give network (helium) with an entity key or a subnetwork (iot, mobile). This is a keyed enrichment: without the Relay key configured it returns available false with a note; the keyless network, hotspot and wallet routes do not need it.

Market-intelligence aggregate over a normalized RWA sub-category: total TVL, the top products ranked with their TVL share, issuer concentration and the leading product's growth trend. Called without a category it returns a market-wide roll-up of every sub-category's TVL and product count. Cited to the open-data source.

Lightweight swap quote for Base without calldata: give tokenIn, tokenOut and raw amountIn and get the max-output route across Aerodrome and Uniswap V3, the buy amount, amountOutMin, price impact and the venues compared. A cheap price check before you build the full transaction.

Corridor safety verdict: given a source chain, destination chain and optional asset/amount, returns every bridge covering that corridor, each with its deterministic risk score and safe/caution/avoid tier, sorted safe-first, plus the recommended bridge and the reasons. One call to pick the safest bridge for a hop.

Composite crypto market sentiment: the Fear & Greed index (value, classification, trend) blended with aggregated news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.

Bridge exploit track record: for one bridge, its hack history (incidents, total USD lost, funds returned, worst technique); with no bridge, a ranked leaderboard of every bridge hack by USD lost. Sourced from DefiLlama's hack dataset, joined and normalized by us.

Crypto Fear & Greed Index: the market Fear & Greed value, classification and trend, blended with aggregated crypto news-headline sentiment into one bullish/bearish/neutral score, optionally focused on a coin or query. Data by alternative.me (attributed) + curated RSS headlines.

Latest holdings for spot Bitcoin or Ethereum ETFs from issuer disclosures: per-fund coin units (or shares), market value and shares outstanding, plus total AUM across funds and the largest fund's AUM share. One normalized call.

Forward-looking token unlock and vesting calendar for one crypto token. Give a ticker, name or slug and get the next unlock (date, token amount, USD value, percent of circulating supply), the full list of upcoming cliff and linear unlocks in a window, the allocation split across team, investors, ecosystem and community, supply metrics and a deterministic 0-100 supply-overhang score. Data from DeFiLlama, cited.
