Science And Education x402 offerings

Institution research-output benchmark for grant offices, research-strategy agents, and comparison shopping — works count, total citations, h-index/i10-index, a 10-year output/citation trend, and topic-strength breakdown (OpenAlex). Optionally benchmark two institutions side by side.

State-of-research synthesis for a specific question — grounded in top OpenAlex + Semantic Scholar results with full citations (DOIs). Built for AI research agents that need a citation-backed starting point fast; explicitly not a substitute for a full systematic review.

Academic paper search across 250M+ works (OpenAlex): title, authors, year, venue, DOI, open-access PDF link, citation count and abstract. Sort by relevance, most recent or most cited.

US college facts from the Department of Education College Scorecard: admission rate, tuition, average net price, graduation and retention rates, median earnings 10 years after entry and median debt.

Compare circuit durations with supplied T1/T2 values using an explicit relaxation/dephasing model. For scenario planning; not a measured device-fidelity guarantee.

Ranks college programs using AI based on criteria and fit.

Verify any US college by name or IPEDS UNITID. Returns tuition (in-state/out-of-state), selectivity (applicants, admit rate, yield), enrollment, and 150% graduation rate. Public-domain NCES IPEDS data.

The n-th Catalan number Cₙ = C(2n, n)/(n+1), counting balanced bracketings, binary trees, and many other structures. Requires n ≤ 10000.

Multinomial coefficient (k1+k2+…)! / (k1! k2! …) — the number of ways to partition n = Σki items into labelled groups of the given sizes. The sum must be ≤ 20000.

Binomial coefficient nCr = n!/(r!(n-r)!), the number of unordered r-subsets of n. Requires r ≤ n and min(r, n-r) ≤ 10000.

Number of ordered arrangements of r items from n, nPr = n!/(n-r)!. Requires r ≤ n and r ≤ 10000.

Exact factorial n! for 0 ≤ n ≤ 20000, returned as a decimal string with its digit count.

Reconcile molarity, mass concentration and fractions when required density and composition inputs exist. Flag missing assumptions; no invented material properties.

Breaks down complex concepts into simpler, easier-to-understand explanations.

Generates structured mappings of relationships between concepts—hierarchies, associations, and semantic links—for knowledge modeling and analysis.

Convert astronomical units to kilometres: send a number, get the converted value with the exact factor (or formula for temperature), the unit category and a rounded human-readable form. Deterministic, no network call. $0.01 per conversion.

Ranks training courses with AI based on relevance and quality.

Grants access to XYZ University course registration for the 2025/2026 academic session.

Classifies course descriptions or syllabi into difficulty levels (beginner, intermediate, advanced) using machine learning.

Propagate declared correlated measurement uncertainty for 1-8 sensitivities using c-transpose C c. Requires exact symmetric positive-semidefinite covariance; returns exact variance and a rational square-root enclosure. First-order only; no empirical covariance validation. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
