Crypto Microdata for Agents

How much will I get, and what do I sign? Best-route swap quote on Base for any token pair: from=USDC|ETH|WETH|cbBTC|DAI|AERO|DEGEN|BRETT|VIRTUAL or 0x.. &to=..&amount=10 (human units) [&wallet=0x.. for ready-to-sign calldata + approval check] [&slippage_bps=50]. Aggregates 100+ Base DEX pools (KyberSwap meta-aggregator, OpenOcean fallback). Returns amount_out, min_out after slippage, effective price, USD in/out, total cost % (price impact + fees), gas + L1 fee in USD, net_out_usd, DEX route, router (with known-router label), verdict GOOD|OK|POOR|AVOID. With wallet=: tx {to,data,value} to broadcast, current allowance to the router, needs_approval + exact approve calldata, and balance check. When to call: before any agent swap or token buy on Base, instead of paying a flat $0.05 swap execution fee. Pair with /crypto/token-risk (is the token safe) and /crypto/decode-calldata (verify the tx). 4xx/no-route never charged.
