x402
Base Intel API — Token Safety Check is a paid API for AI agents from base-intel-api.jakemaxsigal.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-09).
Returns an ALLOW/WARN/BLOCK risk decision for a Base network token contract, combining on-chain safety signals, DEX liquidity data, and activity heuristics into a single graded response.

How this service works
One-call ALLOW, WARN, or BLOCK trade-risk decisions for Base agents, combining contract safety with live DEX liquidity and activity. Paid per result in USDC over x402.
Output
A JSON object containing the token's name, symbol, decimals, total supply, contract address, a numeric safety score (0–100), a letter grade (e.g. A–F), a risk level string (low/medium/high), a list of human-readable risk flags (e.g. 'Upgradeable proxy'), boolean fields for isContract, isUpgradeableProxy, and ownershipRenounced, a timestamp, and a disclaimer note. Paid per call via x402 at $0.01 USDC.
Example use cases
Rug-check before memecoin buy
“I'm about to ape into this new Base memecoin at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — can you run a safety check on the contract first and tell me if it's an ALLOW, WARN, or BLOCK, and what the main risk flags are?”
Autonomous agent trade preflight
“Before my DeFi bot executes this swap on Base, check the token contract at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb for safety — I need a pass/fail decision along with the safety score and any contract red flags so the agent can decide whether to proceed.”
Portfolio token audit
“I hold a few tokens on Base and I'm not sure they're all legit — can you check the contract 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 and give me a risk grade, safety score, and any warnings like unrenounced ownership or upgradeable proxies?”
Technical details
Endpoint
GEThttps://base-intel-api.jakemaxsigal.workers.dev/token/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or DeFi bot needs a single-call, structured risk verdict before executing a token swap or DeFi interaction on Base. It is ideal when you want a combined signal — contract safety, upgradeability, ownership, and DEX liquidity — rather than querying separate data sources. Prefer this over general blockchain explorers when you need a machine-readable ALLOW/WARN/BLOCK style decision at low cost ($0.01 USDC per call) without building your own risk heuristics. Best suited for autonomous agents, trading bots, and portfolio screeners operating on the Base L2 network specifically.
Side effects
- Invalid or non-existent contract address returns an error or empty result
- Non-Base chain addresses may be misidentified or return no data
- Upgradeable proxies may receive a lower safety score even if the token is legitimate (e.g. USDC)
- Rate limiting or payment failure via x402 may block the request
- On-chain data lag may cause stale results for very recently deployed contracts
- Network timeouts from DEX liquidity lookups may delay or fail the response
