LION Trend Intent MCP

LION Adaptive Data Fabric: ONE typed x402 query endpoint that adapts to any agent request over live Base on-chain data, covering multiple verticals from one call. Query params: source (base_dex | token_risk | defi_yields), token (0x address; for token_risk / single-token base_dex), sort (activity|volume|liquidity|age), limit, min_liquidity, max_age_hours, fields (output projection), q (free-text intent). base_dex = ranked active Base tokens (liquidity, volume, price-change, pair-age, activity_score) via DexScreener; token_risk = token security card (honeypot, buy/sell tax, mintable, owner, holders + mechanical risk_flags) via GoPlus; defi_yields = Base DeFi pools ranked by TVL with APY via DefiLlama. Free self-describing capability manifest at the same URL with ?describe=1 (no payment). Returns typed JSON rows + freshness fields (as_of, data_age_seconds, confidence, source_provider). Public keyless data, no API key. Raw public market data only - not financial or investment advice. Pay 0.005 USDC on Base via x402; tools/call returns payment-required metadata only, settle at the paid route to fetch the live JSON.

Live Base (eip155:8453) DEX market-data feed for trading and research agents. Returns a fresh ranked snapshot of active Base tokens with raw on-chain metrics: price_usd, liquidity_usd, volume_h24, volume_m5, price_change_h1/h24, pair_age_hours, dex, and a transparent mechanical activity_score (volume + liquidity + recency). Source: public DexScreener data, no API key. Raw public market data only - not financial or investment advice, no buy/sell recommendation.

Pre-spend payment-term trust check for x402 endpoints. Before your agent signs a Payment-Signature, call this with a target x402/MCP service URL: LION extracts the target live 402 payment terms (payTo, amount, asset, network, scheme), cross-checks them for drift across public discovery surfaces, and returns payment_attempt_blockers, buyer_policy_fit, canonical_purchase_recipe, funnel_stage, a transparent readiness score, and risk_flags so the agent can decide whether to sign. 0.05 USDC on Base eip155:8453. Unpaid tools/call returns JSON-RPC error -32402 with the x402 paymentRequirement; wallet-capable MCP clients (e.g. Coinbase Payments MCP, AWS AgentCore Payments) auto-construct the EIP-3009 signature. LION does NOT perform payment inside MCP. Checks payment-term consistency only - not a smart-contract security audit, no settlement guarantee, no fund movement.

Hardware-wallet buyer-intent + self-custody onboarding-friction intelligence as JSON.
