# Market symbols

For example, `'BTC'` is the expected form in requests, whereas requests with symbol field `'Btc'` or`'btc'` will fail.\
\
All markets symbols are capitalized, except for markets with abbreviated numerical prefixes such as `'kBONK'` and `'kPEPE'` , which have the prefix in lower-case. Requests containing symbol fields such as `'KBONK'`, `'kbonk'`, or `'kBonk'` will fail.
