GET /sequence/region/{species}/{region}Fetch a specific slice of genomic sequence by chromosome coordinates. Returns the DNA sequence for any region you specify (e.g., '13:32315086-32400268' for BRCA2). Unlike the ID-based sequence endpoint, this lets you get arbitrary regions including intergenic areas, promoters, or custom windows around genes. Essential for sequence analysis when you know coordinates but not IDs.
Retrieve genomic sequence for a specific region.
- Region format is `chromosome:start-end` (1-based, inclusive coordinates) - Maximum region size is enforced - very large regions may be rejected - Use `?mask=soft` to get soft-masked repeats (lowercase) or `?mask=hard` for hard-masked (N's) - Strand is always returned as 1 (forward) - you need to reverse-complement yourself if you want the reverse strand
