How this service works
Check supplied FASTA records for malformed headers, duplicate identifiers and invalid sequence characters before dataset ingestion. No functional or safety inference.
Output
Returns a structured result object indicating whether the FASTA records passed validation, along with boundary markers for each parsed record, an input digest for traceability, and a receipt digest for payment verification. Specific issues such as malformed headers, duplicate identifiers, or invalid sequence characters are reported in the result object.
Example use cases
Pre-ingestion genomic pipeline guard
“Before I load this batch of public DNA FASTA records into my database, run a quality check to catch any malformed headers, duplicate identifiers, or invalid nucleotide characters — here's the FASTA content: >sample_001\nATCGATCGATCG\n>sample_002\nGCTAGCTAGCTA”
Synthetic protein sequence QA
“I've generated some synthetic protein sequences and need to validate the FASTA formatting before submitting them — can you check for bad headers, duplicate IDs, and non-standard amino acid characters in this data: >prot_A\nMKLVFFAEDV\n>prot_B\nACDEFGHIKL”
RNA dataset pre-processing validation
“I'm about to ingest this public RNA FASTA file into a pipeline and want to make sure there are no formatting issues — please validate it for malformed headers, duplicate sequence identifiers, and invalid RNA characters: >rna_seq1\nAUGCUAGCUA\n>rna_seq2\nCGAUCGAUCG”
Technical details
Endpoint
POSThttps://www.mahastrategies.com/api/v1/micro/biology-fasta-quality?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, programmatic pre-ingestion check on FASTA data specifically for structural and formatting correctness — malformed headers, duplicate IDs, and invalid alphabet characters. It is not a functional or safety inference tool, so use it as a data quality gate before downstream bioinformatics processing rather than for sequence annotation, alignment, or biological analysis. Prefer it over manual inspection for automated pipeline integration where a per-call audit trail (input and receipt digests) is valuable.
Side effects
- FASTA string exceeds 12,000 character limit — request rejected
- Invalid alphabet enum value (must be DNA, RNA, or protein)
- Malformed JSON body or missing required fields returns an error
- Empty FASTA string (minLength 1 not met)
- Network timeout or service unavailability
