Science And Education x402 offerings

Synastry: Relationship comparison: cross-aspects, house overlays both ways, composite midpoints.

Nakshatras: Sidereal nakshatra, pada and lord of every graha; janma nakshatra with gana, yoni, nadi, varna.

Aspects: Aspects (with orb, exactness, applying/separating) for a moment, or for any longitudes you supply.

Planetary positions: Tropical (or sidereal) longitudes, latitudes, speeds and retrograde flags of Sun..Pluto, nodes, Lilith.

Western natal chart: Complete natal chart: planets in signs and houses, ascendant, MC, 11 house systems, aspects, summary.

Kundli with all 16 vargas: The kundli plus all Shodashavarga divisional charts D1..D60 (Parashara rules).

Compute the astronomical Julian Date (JD, fractional, epoch noon 1 Jan 4713 BC) and Modified Julian Date (MJD = JD − 2400000.5) of a UTC instant. Unlike `calendar`'s integer Julian Day Number, this c…

Determine the astronomical season for a date, based on the Sun's apparent ecliptic longitude (0°=March equinox, 90°=June solstice, …). Defaults to the northern hemisphere; pass `hemisphere` to flip.

Compute the Moon's phase name, age in days since the last new moon and illuminated fraction (0..1) for a UTC date/time. Uses the mean synodic month (29.53 days).

Check one structured public or synthetic low-stakes experiment plan for timing, comparator, outcome and analysis declarations. Returns deficiencies and an integrity receipt. No registration, trusted timestamp, prediction, power analysis or scientific validation. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check one structured public or synthetic low-stakes experiment plan for timing, comparator, outcome and analysis declarations. Returns deficiencies and an integrity receipt. No registration, trusted timestamp, prediction, power analysis or scientific validation.

Author and researcher profile search. An author name returns matching researchers with current affiliation, publication count, total citations, h-index and i10-index, and their most-cited papers — for author lookup, disambiguation, and citation-metrics. Keyless via OpenAlex.

Paid book chapter (x402): Automate the Boring Stuff with Python: What Is Programming. Unit of a larger practical-skills library; free catalog at /library/discovery.json. Book slug: automatetheboringstuffwithpythonnew. Response format: Markdown (.md) for agent parsing. USDC on Base via Coinbase CDP facilitator. Free teasers and discovery.json require no payment.

Uses the geometric AWG definition, so results are exact for solid round conductors. Mass per metre and resistance follow from the material density and resistivity at 20 degrees Celsius; stranded conductors carry roughly two to five percent more mass and resistance per metre than the same nominal size and are not modelled separately. Supply either awg or cross_section_mm2, not both. Sizes 4/0 through 40 AWG are covered.

Calculates beam stress and structural load metrics for engineering analysis.

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.

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.

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.

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.

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.

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.

Full species profile for naturalist and conservation agents. Returns taxonomy, range, IUCN status, behavior, and conservation detail from GBIF and IUCN.
