How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
A JSON object containing: a boolean 'ok', the chain and address echoed back, a schema version, an array of 'reasons' each with a code, points, message, and severity (e.g. 'high'), an overall 'verdict' string, a 'risk_score' integer (0-100), the 'checked_at_block' number, latency in milliseconds, and a disclaimer noting it is heuristic only.
Example use cases
DeFi contract safety screen before swap
“I'm about to interact with 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base — can you run a txpeek pre-transaction check and tell me the risk verdict and any red flags like upgradeable admin keys?”
Agent wallet guardrail before token approval
“Before approving this Ethereum contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 to spend my tokens, run a risk check on it — I need to know if it has proxy risks or dangerous admin controls.”
New token listing risk triage
“We're considering listing this Base token at 0x4200000000000000000000000000000000000006 — can you pull a Tanod txpeek security report so I can see the risk score and any severity flags before we proceed?”
Technical details
Endpoint
POSThttps://tanod.dev/v1/check/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or developer needs a fast (~1 second), cheap ($0.005), heuristic pre-flight risk check on a specific contract or wallet address on Base or Ethereum before initiating a transaction or approval. It is not a full audit, but it surfaces critical signals (proxy upgradeability, admin EOA control, risky functions, verification) that a human or agent should weigh before committing funds.
Side effects
- Invalid address format (not 0x + 40 hex chars) returns a validation error
- Unsupported chain value returns an enum validation error
- Address not found on the specified chain may return empty reasons or an error
- Service timeout if on-chain data is slow to fetch (typical ~1.2s but may exceed)
- Payment failure (x402 micropayment not accepted) blocks the call
