Peepeth's data is open to anyone. The contract is stateless, except for recording unique usernames, so you have to query each block and parse the input data of each transaction according to the following ABI.

For more about stateless contracts, check out this great post.

The ABI and address are all you really need to read and write from Peepeth, but actually implementing a front-end is pretty labor intensive as there are many moving parts. Peepeth.org will make it easier for others to start their own front-ends (by providing code examples).
