Uses the Kozeny-Carman relation with supplied porosity and pore diameter, then applies Darcy’s law with supplied thickness, viscosity and pressure drop. It is an idealized homogeneous porous-medium calculation, not scaffold design validation, cell-transport modeling, biocompatibility assessment or medical guidance.

▸ GET /v1/allergen-epitopex402 ! Unstable
Builds amino-acid k-mer sets, calculates Jaccard similarity, and finds the highest contiguous identity between each supplied epitope and any equal-length window of the query. It does not predict immune binding, allergenicity, cross-reactivity or clinical risk and cannot replace curated databases or laboratory testing. $0.004 · 12 ms · Base ▸ GET /v1/crispr-offtargetx402 ! Unstable
Compares one guide with caller-supplied candidate protospacers, weights mismatches in the guide’s final ten positions twice, applies a simple NGG PAM penalty, and ranks a transparent similarity score. It does not search a genome, model bulges, chromatin or nuclease-specific biology, and must not be used as a clinical or laboratory safety decision. $0.004 · 13 ms · Base ▸ GET /v1/phage-matchingx402 ! Unstable
Slides each caller-supplied spacer over a bounded phage sequence in both orientations, records its minimum Hamming distance and reports matches within a caller-selected mismatch threshold. It does not account for PAMs, phage taxonomy, infection biology, escape, host range or therapeutic suitability. $0.004 · 10 ms · Base ▸ GET /v1/protein-foldingx402 ! Unstable
Checks that a hydrophobic/polar sequence follows a self-avoiding unit-step lattice path, then counts non-consecutive hydrophobic contacts and assigns one negative energy unit per contact. It evaluates a supplied toy conformation only; it neither predicts a fold nor represents atomic chemistry, kinetics, solvent or biological function. $0.004 · 12 ms · Base ▸ GET /v1/biomarker-longevityx402 ! Unstable
Standardizes each supplied value against its supplied mean and standard deviation, flips markers whose favorable direction is lower, and computes a weighted composite mapped to a bounded 0–100 index. The references and weights come entirely from the caller; this is not a validated longevity score, diagnosis, prognosis or medical advice. $0.003 · 10 ms · Base ▸ GET /v1/dna-storage-encodex402 ! Unstable
Maps each two-bit group of caller-supplied UTF-8 bytes to A, C, G or T and reports a SHA-256 checksum of the original bytes. This reversible representation performs no biological synthesis, homopolymer balancing, GC optimization, addressing or error-correcting code. $0.003 · 31 ms · Base ▸ GET /v1/microbiome-diversityx402 ! Unstable
Normalizes non-negative caller-supplied taxon counts and computes observed richness, natural-log Shannon entropy, Simpson diversity and Pielou evenness. It does not perform sequence classification, compositional correction, rarefaction, cohort comparison or medical interpretation. $0.003 · 30 ms · Base ▸ GET /v1/pathogen-r0x402 ! Unstable
Multiplies per-contact transmission probability, effective contacts per day and infectious duration to obtain a simple basic reproduction number, then applies a susceptible fraction for an effective number. It is a classroom homogeneous-mixing calculation, not an outbreak estimate, fitted epidemiological model or public-health forecast. $0.003 · 395 ms · Base ▸ GET /v1/syn-yeast-yieldx402 ! Unstable
Divides each available substrate mass by its required mass per product mass, selects the limiting substrate, and applies a caller-supplied process efficiency. It does not model yeast metabolism, kinetics, oxygen transfer, toxicity, regulation or actual fermentation performance. $0.003 · 10 ms · Base ▸ GET /v1/tissue-scaffoldx402 ! Unstable
Uses the Kozeny-Carman relation with supplied porosity and pore diameter, then applies Darcy’s law with supplied thickness, viscosity and pressure drop. It is an idealized homogeneous porous-medium calculation, not scaffold design validation, cell-transport modeling, biocompatibility assessment or medical guidance. $0.003 · 10 ms · Base Same category, ranked by Trust score — switch to a more reliable or cheaper source.
