HALOWERK kettenwerk — Token Authority Inspector
x402
HALOWERK kettenwerk — Token Authority Inspector is a paid API for AI agents from kette.netzhandwerker.de, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Analyzes a smart contract token's privileged authority addresses (owners, admins, minters, pausers, etc.) across major EVM chains, optionally simulating calls to dangerous functions to verify access control.

How this service works
HALOWERK kettenwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a structured breakdown of all privileged authority addresses found in the token contract (e.g. owner, admin, minter, pauser, blacklister), their roles, and — if probe_calls is enabled — the results of read-only simulated calls to potentially dangerous functions showing whether access is restricted or open.
Example use cases
Pre-investment rug-pull risk check
“Before I buy into this new Base token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefd4, can you check who holds authority over it and whether anyone can mint or pause it without restrictions?”
DeFi protocol centralization audit
“I need to audit the Arbitrum token at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC6 for centralization risk — pull all the privileged roles and simulate the dangerous functions to see if they're gated properly.”
Token security review before listing
“We're considering listing a Polygon token at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on our platform — can you inspect its authority addresses and probe whether the dangerous functions are actually access-controlled?”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/token/authoritiesWhen to prefer
Use this endpoint when you need to quickly surface centralization and rug-pull risks in an EVM token contract without running a full audit. It is especially valuable for pre-investment due diligence, exchange listing checks, or DeFi protocol risk scoring, where you need to know who can mint, pause, freeze, or upgrade a token. Prefer this over generic block explorers when you want structured authority data and active access-control simulation rather than raw ABI browsing.
Side effects
- Invalid or non-checksummed contract address returns a validation error
- Contract address exists but is not a token contract — may return empty or partial results
- Unsupported chain value returns an enum validation error
- Contract has no recognizable authority functions — returns empty authority list
- RPC or on-chain read failure for the specified chain may cause partial results or timeout
- probe_calls simulation may be inconclusive if contract uses non-standard access patterns
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| chain | string | Chain the token lives on. |
| token | string | Token contract address. |
| probe_calls | boolean | Simulate each dangerous function from a neutral address to test whether access is restricted. Read-only, nothing is sent. |
