Provides ERC-20 token risk analysis and swap route data for tokens on Ethereum (and Base), including contract owner-power checks, honeypot risk signals, quotes, approval targets, and unsigned swap transactions.
Enables purchasing prepaid API call packs by card through Stripe when an agent's free calls are exhausted.

ERC-20 honeypot check and swap route data — a single-purpose MCP server for AI agents. No install, no account: it runs as a remote server; this repo also has a zero-dependency stdio bridge.

| 3 free calls per agent, then 0.99 USDC | Reads 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 owner share of supply. Risk |

The first 3 paid calls per agent are free (identify your agent with the header X-API-Key, or set ANGEL_API_KEY for the stdio bridge). After that each call is paid per request in USDC on Base via x402 (params._meta["x402/payment"]), with a prepaid pack (bundle_token) or by card (buy_pack_with_card). The 402 answer names the exact amount and the pay-to address before anything is signed.
Angel is a technical data and risk-analysis service only: no custody, no execution or transmission of orders, no investment advice. The disclosed 0.5 % integrator fee is a technical API provisioning fee for computing the route data; the aggregator deducts it inside a swap you send yourself. Signals from on-chain code — sell restrictions that only trigger during a trade are not simulated.
