Policies & conditions

A policy is one provider plus one or more conditions. Base checks the user's credential against it before signing a verification. Operators: eq, gt, gte, lt, lte, in.

Provider	Condition	Type	Operators	Example
`x`	`followers`	int	`eq` `gt` `gte` `lt` `lte`	`followers gte 1000`
`x`	`verified`	bool	`eq`	`verified eq true`
`x`	`verified_type`	string	`eq`	`verified_type eq blue`
`coinbase`	`coinbase_one_active`	bool	`eq`	`coinbase_one_active eq true`
`coinbase`	`coinbase_one_billed`	bool	`eq`	`coinbase_one_billed eq true`
`instagram`	`followers_count`	int	`eq` `gt` `gte` `lt` `lte`	`followers_count gte 5000`
`instagram`	`username`	string	`eq`	`username eq base`
`tiktok`	`follower_count`	int	`eq` `gt` `gte` `lt` `lte`	`follower_count gte 10000`
`tiktok`	`following_count` / `likes_count` / `video_count`	int	`eq` `gt` `gte` `lt` `lte`	`video_count gte 50`

Declaring a policy

Return the policy from your contract's provider() and conditions(). Each Condition is { name, op, value } as strings:

function provider() external pure override returns (string memory) {
    return "coinbase";
}

function conditions() external pure override returns (Condition[] memory) {
    Condition[] memory c = new Condition[](1);
    c[0] = Condition("coinbase_one_active", "eq", "true");
    return c;
}

An unsupported provider, condition, or operator makes the API return 400 invalid_policy and no verification is issued.
