Latest releases of the 10 main Ethereum clients as JSON: execution (go-ethereum, Nethermind, Besu, Erigon, Reth) and consensus (Lighthouse, Prysm, Teku, Nimbus, Lodestar). Version, date, days since release, link to notes, and a plain keyword flag when notes mention security or urgent upgrades.

Did this Base payment settle? Status, block, timestamp and confirmations for one transaction hash, with its ERC-20 Transfers decoded (token, from, to, amount; up to 100 listed, transfers_total gives the full count) and any EIP-3009 authorization used, plus match flags for an optional expected payTo and amount, so an x402 PAYMENT-RESPONSE can be checked. Required: hash. $0.002 USDC on Base. Transac

DeFi TVL from DefiLlama: top protocols filtered by category and chain (TVL, 1d/7d change, market cap, chains), chain TVL rankings with protocol counts, or one protocol with per-chain TVL split and 90 days of daily TVL history.

DeFi protocol detail by DefiLlama — full historical TVL plus per-chain and per-token breakdowns for one protocol by slug.

Query real-time stablecoin supply yield pools from Barker's index of 500+ DeFi protocols. Returns ranked rows with protocol_name, chain_name, asset_symbol, supply_apy_total (decimal — multiply by 100 for %), and supply_tvl (USD). Use for questions like 'best stablecoin yield', 'where to earn on USDC', 'compare lending rates', '稳定币利率'.

Find the best DeFi yields across 500+ protocols and all major chains: filter by token (USDC, ETH...), chain, protocol, stablecoin-only and minimum TVL; returns APY (base + reward), 30-day mean APY, 7-day change, TVL, impermanent-loss risk and outlook. Sort by APY or TVL.

Total value locked (USD) for one DeFi protocol by DefiLlama slug or name (e.g. "aave-v3", "lido", "uniswap-v3"): current TVL, per-chain TVL breakdown, 1h/1d/7d TVL change, category, chains, token symbol and market cap. Optional `chain` also returns that chain's TVL for the protocol. Unknown names return `found:false` with slug `suggestions`.

Retrieve a derived chain or protocol activity proxy. Include scope and a canonical target such as Ethereum or a protocol slug.

All Base protocol stats — TVL, categories, top protocols. Data from DeFiLlama.

Details for one on-chain DeFi lending pool (Aave v3, Compound v3, Moonwell, Morpho Blue) by pool id protocol:chain:token_address: supply APY, borrow APY, utilization, TVL and 0-100 risk score. Example: pool_id=aave-v3:base:0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 (Aave Base USDC). Pool ids come from /v1/lookup/yields results. Refreshed about every 30 min

Arithmetic comparison of a USDC settlement against comparator percentages YOU supply (bank_fee_pct, custodial_fee_pct) across 14 global fiat currencies. The comparators are assumptions, not measurements of any bank or provider; no protocol fee is deducted on this rail.

Use when you need callable agent services for a capability across protocols: x402 listings ranked by relevance weighted by 30-day paying wallets, plus hosted MCP servers from the Official MCP Registry (a capped subset, count in coverage; those naming x402, L402, MPP or pay-per-call first; that registry publishes no prices). L402 and MPP listings are not covered. ?q= required. $0.002 USDC per call.

Free proxy API: get one fast, verified-alive proxy (HTTP, SOCKS) filtered by country, protocol and anonymity, for scraping

Fetch a site's robots.txt and evaluate crawl permissions: given a URL (plus optional extra paths) and a user-agent, return whether each path is allowed or disallowed, the rule that matched, the user-agent group, the crawl-delay and any declared sitemaps. Implements the Robots Exclusion Protocol (RFC 9309) with longest-match-wins, Allow-over-Disallow tie-breaking and * / $ wildcards.

Smart contract security check before you approve or pay an address: reads the bytecode, behind proxies too, for privileged functions (mint, pause, blacklist, upgrade), dangerous opcodes and protocol type, and checks whether a single key holds those powers. Adds OFAC SDN screening, who funded the address, sybil-filtered ERC-8004 reputation for agents and a 0-100 score with proceed / hold / block. S

0-100 safety score with components (protocol trust, TVL depth, audits, track record), observed and risk-adjusted APR, and whether STB's Auto-Defense would exit — for every vetted stablecoin vault, or one by ?venue=<id|pool address>.

Library sources that are new or updated in an inclusive date window. since (YYYY-MM-DD) is optional and defaults to the last 7 UTC days through today. Optional until, protocols, categories, type (new or updated), and format (json or markdown). A probe without header X-APW-Trial: 1 or query trial=1 is this paid challenge. One request is 0.01 USDC.

DeFi position and wallet risk snapshot on Base: token balances, account flags, and live Aave v3 collateral, debt, borrowing power, and health factor read directly from the protocol at a specific block, plus derived risk metrics — net equity, LTV utilization, leverage multiplier, health-factor band, and collateral drawdown tolerance (how far collateral can fall before liquidation). For agents asses

Follow the money out of a wallet. Walks outflows hop by hop under a causal gate (each hop must post-date the last and carry continuous value) until it reaches an exchange deposit, a bridge, a swap venue, or runs out of trail. Returns every hop with its labelled destination, the token-leg outflows alongside the SOL leg, and whether the trail ended at an exchange or a privacy protocol.

Bitcoin protocol and software changes as JSON: Bitcoin Core merges and releases, BIP updates, Lightning spec and implementation changes. Each item has status (proposal, merged, released, activated), layer (consensus, policy, p2p, wallet), why it matters, what has not happened yet, and primary source links.
