- DeFi quote and risk routing — best swap route on Base (free route data)
Best swap route on Base or Ethereum for a token you checked with token_risk: quote, minimum out, approval target and, with taker, the unsigned transaction your agent signs and sends itself. Angel is a technical data and risk-analysis service only: it computes structured route data from public aggregator quotes and checks token risk. No custody, no execution or transmission of orders, no investment advice — your agent decides, signs and sends the transaction from its own wallet. The 0.5 % integrator fee is a technical API provisioning fee for computing the structured route data; the aggregator deducts it inside the swap and sends it to Angel's wallet, and buy_amount is already net of it. No charge per call. A2A (no sign-up): message/send with a data part {"skill":"swap_route","input":{"chain":"base","sell_token":"USDC","buy_token":"WETH","sell_amount":"10000000","taker":"0xYourWallet"}}. HTTP: POST https://angel.oroboros-design.com/agenten/signal/swap-route.
- ERC-20 honeypot and rug-pull check — Base, Ethereum (USDC on Base)
Honeypot and rug-pull check for an ERC-20 on Base or Ethereum before a swap, approval or signature, read straight from the contract: upgradeable proxy (EIP-1967, beacon, clone), owner powers in the bytecode (mint, pause, blacklist, fee or max-tx setters, trading switch, burn from any address), owner renounced or active and the owner's share of supply; known issuers labeled. Risk low, medium or high with reasons. Signals, not investment advice. 0.99 USDC per check, first 3 calls per agent free. Low or medium risk returns recommended_next_step for swap_route. A2A (no sign-up): message/send with a data part {"skill":"token_risk","input":{"token":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","chain":"base"}}.

Before your agent pays: is the x402 asset the real USDC (not a look-alike token), is the amount sane, does payTo have on-chain history, is there an agent card, is the Moltbook account claimed and established? Score 0–100 and verdict pay | caution | do_not_pay with every reason — 0.01 USDC. HTTP only — free preview: GET https://angel.oroboros-design.com/agenten/vertrauen?url=…; full: POST https://angel.oroboros-design.com/agenten/vertrauen {"url": "…", "agent": "…", "payTo": "0x…"}; checkout: https://angel.oroboros-design.com/agenten/kasse
