Every character on Jiǎoluò Shūwū read as jia in any tone — 2 readings total across the four tones. Pick the tone you mean.
If you have the sound jia but not the character, here are the 2 characters read this way: 家 (jiā, home, family), 价 (jià, price, value, worth). They split across 2 tones, so the tone is what separates them.
