TokenSniffer

TokenSniffer's Smell Test combines several checks into a token score. Read the individual findings beside that number: contract permissions, holder concentration and liquidity conditions answer different questions. The score can change when fees, ownership distribution or liquidity locks change. It is a screening signal, not a guarantee that a token will remain tradable or retain its value.

For developers, Get Token takes the blockchain identifier and token-contract address. The default response does not include the full metrics or test results. Request those with include_metrics and include_tests, and request contract comparisons separately with include_similar. Detailed metrics and tests are available only for the chains listed in that endpoint's documentation.

The response can be pending while analysis is prepared; block_until_ready changes whether the request waits for completion. Keep the API key on the server. The current endpoint authenticates with an X-API-Key header, and ordinary published limits include five requests per second and up to five pending token queries.

Sniffer Pack Pro costs $99 monthly or $1,128 annually, with 500 token requests per day. Repeat requests for the same token do not consume additional unique-token quota under the published rules. Enterprise starts at 5,000-plus daily token requests and uses a custom quote. A 14-day trial is available by request.
