That site is new to me... given the lineup, I'm skeptical. Several in the 'View Your Offers' lineup DO NOT provide (Riley Reid for one), while several in the 'Expired Offers' definitely do (Veronica Avluv).

Few red flags...
1-They list someone who has been very open for YEARS about her opposition to providing (Lisa Ann)
2-They list Brandi Love and post a lot pf PERSONAL info about her (Don't care to know her real name or her husbands name...TMI)
3-They list Diamond Jackson who has no prior history of providing (even UTR)

Mia Khalifa, Lisa Ann do not escort. Mia is long retired. Ava did provide under a different name.

They seem to make it clear -- well, as clear as I can tell -- that they do not do booking or make appointments. They are middlemen who let their "stars" -- who pay starinbed to advertise there -- know that someone is interested in meeting them.  
.
I'm not about to test it out but I'll guess that the client pays a small fee to starinbed to have their request forwarded to the Waste Basket -- I mean, forwarded to the STAR -- that they are interested. When the star fails to reply, that is not starinbed's fault so the client is out of luck and out of their payment.  
.
Or if it's like other scam services, maybe they charge per message and lure you into an exchange of several messages:  
Client: I'm interested in meeting X.  $$
Reply: She wants to know more about you: age, etc.
C: Here you go. $$
R: X travels. Where are you located?
C: Right here! $$
R: Are you available in late June?
C: Yes! $$
R: Too bad. X isn't. How about July in a different city?
C: Yes! $$
... Like a Nigerian 419 Scam.

If starinbed is legit, I apologize in advance. I am just the skeptical type.

Looks like a total scam to me. starinbed.com redirects you to another site pcngyh.com which asks for your credit card information to create a "dtf today" account. First, its asking for credit card info just to create an account that will charge you on a monthly basis but won't tell you the cost. Second, there is no "dtf today" provider site. So total scam as far as I'm concerned.
