No, and that is deliberate. SnagRes watches Casa Mono on OpenTable around the clock and tells you the moment a table appears, by email or text. You book it yourself, in your own account, at the restaurant's own price. Nothing is reserved, held or resold on your behalf, which is the line New York's 2024 reservation law draws and the line we stay on the right side of.
Because you cannot say any of the above about a directory. SnagRes tracks 284 restaurants across New York, San Francisco, Los Angeles and Chicago, with 61,530,416 logged availability checks between the rooms with a full record. Nothing watching tens of thousands of restaurants can tell you that one Union Square Spanish room is 100% open on every night alike, because nothing is watching it closely enough to count.
