Keyless, pay-per-call crypto + DeFi data for autonomous agents on Base (x402 / gasless USDC, no signup, no API key). Most-used routes: DeFi pool yields across chains with APY base/reward split, TVL and sustainability prediction (/defi/yields); live spot prices by symbol or id (/crypto/prices); fear-and-greed (/crypto/fear-greed); and multi-venue perpetual futures funding rates reconciled across five venues -- Binance, Bybit, OKX, Hyperliquid and dYdX -- with the computed CEX-to-DEX arb spread (bps), cheapest-long/richest-short venue, annualized funding per venue and a LONGS_PAY/SHORTS_PAY signal returned in one call (/crypto/funding). Token safety and pre-trade checks: one call returns a SAFE | CAUTION | AVOID verdict with a 0-100 risk score for any Base token -- honeypot/sellability simulation, measured buy/sell tax, owner concentration, total holder count and largest-holder (whale) concentration -- the single biggest non-contract, non-locked, non-owner wallet that could dump its position, as a share of supply, so holder distribution and ownership concentration are visible without a separate indexer -- mint/pause/blacklist/upgradeable-proxy checks, Uniswap v3 WETH liquidity, and a Sourcify source-verified signal that confirms the contract's published source byte-matches the on-chain bytecode on Base chainId 8453 -- a positive transparency signal that never inflates the risk score (/chain/token-report, /chain/token-security, /gate/swap). The risk scorer is calibrated so blue-chip tokens (USDC, cbBTC) clear at a low score (26/100) instead of triggering false-positive 'review' alarms the way generic scanners do, while honeypot, high-tax and owner-concentration flags are never dampened. Prospective-transaction simulation predicts whether a transaction will revert before you send it, returning the decoded revert reason, gas, and asset-change estimates (/chain/simulate). Base RPC primitives (balance, nonce, gas, receipt, tx, token-balance, allowance) and a yield-entry verdict round it out. 60+ routes from $0.001. MCP security scanning: a free static scan of any MCP server's tools/list (/scan/mcp, /scan/mcp/preview) flags wallet-secret / wallet-drainer parameter harvesting (private-key, seed-phrase, mnemonic inputs), tool poisoning, prompt-injection and remote/dynamic instruction-injection (fetch-and-obey rug-pull) patterns, returning an A-F grade and an admit/block verdict. Free previews on every route; full manifest at /.well-known/x402, MCP at /mcp. Monitored MCP servers are re-scanned continuously: drift alerts flag any A-F security-grade regression (grade worsened between sweeps) so a supply-chain change that degrades a server's posture is caught over time, not just at one-off scan (/scan/verify/status, continuous monitoring from $9.99/mo at /pricing). Every scanned server also gets a public report page (/scan/report) showing an A-F security grade; for monitored servers it renders a dated grade-history timeline and the grade trend across recorded scans (e.g. 'A -> F over the last N scans, regressed 2 bands') plus the exact findings that appeared or resolved at each change -- an SSL-Labs-style public security scorecard for MCP. Agent-to-agent discovery: this API is also published as an ERC-8004 registration-v1 file (/.well-known/erc-8004.json, type eip-8004#registration-v1, x402Support:true) cross-linked to its A2A agent card and x402 manifest, so trustless-agent registries and ERC-8004 explorers discover its 64 x402-payable routes, per-task USDC pricing on Base (eip155:8453), supported-trust model and MCP endpoint in a single keyless fetch. Counterparty screening -- sanctioned OR scammer in one call: /chain/wallet-screen lets an agent check if a wallet address is sanctioned or a scammer before it sends, swaps or approves, returning a blocked | clear verdict plus independent 'sanctioned' and 'malicious' flags by exact match against TWO sources -- (1) the authoritative U.S. Treasury OFAC SDN crypto-address list and (2) merged community scam/phishing/wallet-drainer threat-intel (ScamSniffer scam-database + MyEtherWallet ethereum-lists darklist, 3,182 addresses) -- with the snapshot date on every answer, so the decision is reproducible and auditable. Unlike sanctions-only screens, it also catches known scammer/drainer/phishing addresses that are on no government sanctions list; 'clear' means absent from both snapshots, not a safety guarantee ($0.004, free live preview, also MCP tool chain_wallet_screen). Pre-payment endpoint check -- should an agent pay this x402 URL? Before it pays an unknown x402 endpoint, /x402/preflight fetches the URL once (never pays) and returns PAY | CAUTION | AVOID in one read-only call: it validates the 402 challenge and accepts[] (scheme/network/asset/payTo/amount and the top-level resource = will it settle) AND screens the payTo address against the OFAC + community scam/drainer lists and runs a static LLM01/LLM08 prompt-injection scan of the resource and any advertised MCP tools (safe to pay), with a per-check breakdown and fix hints. One call answers both 'will it settle' and 'is it safe to pay', where most preflight listings answer only one. Read-only, never pays, not a settlement guarantee ($0.001, free preview 3/IP/day, also MCP tool x402_preflight). The same preflight call also takes an optional &samples=N (N=1-5) to run a point-in-time RELIABILITY/PAYABILITY burst: it probes the 402 challenge N times in a single call and returns settle_consistency (e.g. 3/3), settle_rate, reachable_rate, a stable flag, and latency_ms min/median/max across the probes, downgrading a flapping endpoint from PAY to CAUTION -- so an agent sees whether an x402 endpoint settles consistently or only intermittently BEFORE paying, not just on a single probe. This is a burst sampled at call time, honestly scoped as such: it is not historical uptime data and not a signed continuous-monitoring alert (/x402/preflight?samples=N, $0.001, free preview). For a FAILING x402 payment path, the same per-check breakdown doubles as a debug/test tool: it names exactly WHY a given endpoint will not settle (malformed scheme/network/asset/payTo/amount, or a missing top-level resource field) so a builder can test and fix the seller endpoint before any agent pays it, and an agent can decide whether this x402 seller is safe to pay.
