Further guidance
Correct Form

Fast Test
If “sparked my curiosity” fits, use “piqued my interest.” If you mean “reached the highest point,” use “peaked.”
Word Boundary
“Peak” can be a noun, adjective, or verb connected with a high point, but that is a different meaning from the verb “pique” used with interest.

The established expression for an advance preview is “sneak peek.” “Peek” means a quick look; “peak” refers to a highest point or summit and does not form the standard preview expression.
The established expression is “bad rap,” referring to severe criticism, an unfavorable judgment, or an unfair accusation depending on context. “Bad wrap” is not the standard spelling of that expression; “wrap” has its own unrelated meanings.
The established expression is “with bated breath,” used for waiting in an anxious or excited way. Cambridge records “bated” in this fixed phrase. “Baited breath” is a sound-based spelling confusion, not the form supported by the reviewed dictionary evidence.
The established expression is “at someone’s beck and call,” meaning ready and willing to do whatever that person asks. “Beckon call” is a common mishearing or eggcorn, not the standard form of the idiom.
“Champing at the bit” and “chomping at the bit” are both used for being very eager or impatient to begin. Cambridge explicitly records champing/chomping as variants; “champing” reflects the older horse-related wording, while “chomping” is a widely accepted modern variant.
“Couldn’t care less” means not caring at all and is the clearest form across English varieties. Cambridge also records “could care less” as a US informal variant used with the same intended meaning, despite its literal wording appearing logically opposite.
The established adjective is “deep-seated,” meaning strongly rooted, firmly established, or difficult to change. “Deep-seeded” is a common reinterpretation when this meaning is intended, even though a literal seeded construction can occur in unrelated contexts.
The standard expression is “dog-eat-dog,” describing a situation in which people compete ruthlessly for their own advantage. “Doggy-dog” is a sound-based reinterpretation, not the standard form of the expression.
