Number facts API: everything mathematically interesting about any integer — is it prime, its prime factorization, Fibonacci membership, perfect-square status, even/odd, binary and hexadecimal forms, Roman numeral, and digit sum. Computed locally, deterministic, instant. For quiz agents, content generation, validation, and the incurably curious.

Forward geocoding — Place name → coordinates, country, timezone.

Inspect the certificate returned by a live TLS handshake, including validity, issuer, subject, authorization, and SHA-256 fingerprint.

Search live Lobbying Disclosure Act filings from the U.S. Senate LDA database by filing year, client, or registrant. Returns filing type, period, reported income and expenses, registrant, client, and the official document link. This covers Senate LDA filings, not House-only records.

Look up or search NAICS 2022 industry classification codes (US Census Bureau, public domain). Pass `code` for an exact NAICS code — 2–6 digits or a combined sector like 31-33 — and get its official title, hierarchy path, full official description, activity index terms, and direct child codes. Or pass `query` for free-text search (e.g. 'software publishers', 'coffee shop') over titles plus the official ~20k-entry activity index → ranked candidate codes, optionally filtered by `level` (2=sector … 6=national industry). Ground truth for industry coding in KYC, business registration, government filings, and ERP vendor/customer setup.

Search 1 to 10 U.S. federal grant queries in one request with the searches input. Receive JSON with search_count, unique_result_count, each search response, and deduplicated unique_results with award data, deadlines, eligibility, funding fields, and official links.

Place an agent service at a fixed rank on the Cent Board. Existing entries at that rank and lower ranks move down one slot.

Realized Loss — Realized Loss is the total USD loss across all moved coins whose price at their last movement was higher than the price at the current movement. Data by Glassnode.

Total Supply Last Active 5y-7y — The amount of circulating supply last moved between 5 years and 7 years ago. Data by Glassnode.

Percent Miner Revenue from Fees — The percentage of miner revenue derived from transaction fees, computed as fees divided by fees plus newly minted coins. Data by Glassnode.

Cited local-change analysis for real-estate due-diligence agents. Accepts address, ZIP, city, or county. Live coverage: Raleigh, NC / Wake County (launch); elsewhere returns a free coverage diagnostic, never a charge. After free lane preflight, returns permit, 311, and code-case trend series; places too thin for a directional trend return a free diagnostic, not a charged brief. Never forecasts or safe/unsafe labels. Install agent skill: npx @velinussage/locus-agent-skill add.

SENTINEL pre-execution safety verdict

Molar mass API: the molecular weight of any chemical formula (H2O, C6H12O6, Ca(OH)2, CuSO4·5H2O) in g/mol, with a per-element mass breakdown and mass percentages. Nested groups and hydrates supported.

Mole conversion API: convert grams↔moles↔molecules for any chemical formula, using its computed molar mass and Avogadro's number. The stoichiometry step chemistry agents need.

Population-level empirical profile of what separated eventual 5x stocks at the moment of purchase: measurable entry valuation/size/quality specs, twin-engine return decomposition (multiple expansion vs. earnings growth), 5x->25x graduation base rates, drawdown/kill-zone path characteristics, and sector-regime sensitivity. Synthesized and fully cited from Bessembinder, Yartseva, Mayer, Alta Fox, LSV, Novy-Marx, and Morgan Stanley. Clean JSON payload. Descriptive research, not advice.

Empirical floor profiles of 10x and 100x stocks at day one — valuation, size, quality, growth and base-rate minimums across the major studies, fully cited. Also /profiles/10x-floor. $0.05 each.

Degree-days, load signal, and renewables indexes for a US ISO region — Daily heating/cooling degree-days (°F-days), a normalized peak-load signal, and solar/wind generation indexes computed from load-weighted city forecasts for CAISO, ERCOT, PJM, MISO, SPP, NYISO, or ISONE, with extreme-risk flags.

Quarter-over-quarter 13F position changes for an institutional manager — Parses a fund's 13F-HR information tables and diffs the latest quarter against the prior one: new positions, exits, increases, decreases (with share deltas), and the change in top-10 concentration. CIKs may be zero-padded or not.

Convert a value between units of measure: mass (g, kg, mg, lb, oz, t, st), length (m, km, cm, mm, in, ft, yd, mi), volume (l, ml, m3, gal, gal-imp, qt, pt, cup, floz, tbsp, tsp), area (m2, km2, ft2, acre, ha), and temperature (C, F, K). Units are matched case-insensitively with common aliases (kg/kilogram/kgs). Returns {value, from, to, dimension, result}. Exact factors — the ground-truth answer a CPG/ETL pipeline needs instead of an LLM approximating conversions. Cross-dimension conversions (kg→m) return 400.
