# Consul Intention Check
Command: `consul intention check`
Corresponding HTTP API Endpoint: [\[GET\] /v1/connect/intentions/check](/consul/api-docs/connect/intentions#check-intention-result)
The `intention check` command checks whether a connection attempt between
two services would be authorized given the current set of intentions and
Consul configuration.
This command requires less ACL permissions than other intention-related
tasks because no information about the intention is revealed. Therefore,
callers only need to have `service:read` access for the destination. Richer
commands like [match](/consul/commands/intention/match) require full
intention read permissions and don't evaluate the result.
-> **Note:** This command will always treat intentions with `Permissions`
defined as _deny_ intentions during evaluation, as this endpoint is only suited
for networking layer 4 (e.g. TCP) integration.
The table below shows this command's [required ACLs](/consul/api-docs/api-structure#authentication). Configuration of
[blocking queries](/consul/api-docs/features/blocking) and [agent caching](/consul/api-docs/features/caching)
are not supported from commands, but may be from the corresponding HTTP endpoint.
