After some years of inactivity I'm updating BioSmalltalk (a bioinformatics library) for Pharo with the latests changes in NCBI services. One of these services, called QBlast, seems to be no longer accessible :

http://web.archive.org/web/20090125100600/http://www.ncbi.nlm.nih.gov/BLAST/Doc/urlapi.html

Clicking around, I've arrived to this (potentially) alternative service: https://ncbi.github.io/blast-cloud/dev/api.html but it seems to be "DEPRECATED".

Anyway I tried to send a request using the QBlast API, following recommendations in this biopython thread, which would be :

BioNCBIWebBlastWrapper new nucleotide
            query: 'CCCCATGCATATAAGCAAGTACATGACCTCTATAGCAGTACATAATACATATAATTATTGACTGTACATAGTACATTATGTCAAATTCATTCTTGATAGTATATCTATTATATATTCCTTACCATTAGATCACGAGCTTAATTACCATGCCGCGTGAAACCAGCAACCCGCTAGGCAGGGATCCCTCTTCTCGCTCCGGGCCCATAAACCGTGGGGGTCGCTATCCAATGAATTTTACCA';
            hitListSize: 10;
            filterLowComplexity;
            expectValue: 10;
            wordSize: 10;
            blastn;
            formatTypeXML;
            alignmentViewFlatQueryAnchoredNoIdentities;
            fetch.

This translates into:

Any idea what I should look to update?

This is the first bytes of the HTML page I get so far:
