RHLS — for agents & developers

Deterministic, offline-first services you can call from code or an agent loop. English-first. Everything below is live right now.

1. Lingua Mundi lexicon API

Base: https://quote-taking-lincoln-competing.trycloudflare.com (live public endpoint, key-gated — free key via https://quote-taking-lincoln-competing.trycloudflare.com/keys)

Endpoints: /analyze?text=cat&language=eng · /kanji?q=水 · /graph/sky (concept sky: 220 stars, edges, per-language words) · /openapi.json

Corpus: 561k+ lexemes, 810k+ senses, Japanese 283k / English 47k / Spanish + others (imports running).

Read-class (Observe-mode safe — no side effects, agent-friendly).

2. Deterministic drivers (MoreComp)

driver	what it does	class
retrieval	Obsidian KB grep (`kb <term>`)	read
ocr	`ocridx` FTS5 search over an OCR index	read
text-check	LanguageTool 6.6 grammar/typo	read
translate	Argos NMT — offline es↔en	read

Every driver returns a frozen {capability, args, context} contract — no prose, no surprises.

3. Pricing (English-first, launch)

Tier	Price	What you get
Free	$0	rate-limited API + openapi.json, 1 driver
Agent	paused	not for sale yet — the key gate is being wired (the previous button wrongly pointed at the Complete bundle). Free tier below stays open.
Fleet	custom	corporate: lexicon dumps, SLAs, self-host kits

Agent tier paused — no purchase button until the key gate is wired. Free key via the endpoint above.

4. Why agents trust it

Deterministic: drivers are read-class, output is schema-validated (no hallucinated tools).
Offline: the whole stack runs on a laptop — no vendor lock, no data exfiltration.
MIT core: the Rust core and this page's stack are open source (see the repo).
Verifiable: every release passes a dual adversarial audit (see the store).
Governance-ready: spend caps, human-approval mode and audit trails on every action (the approval gate) — built for enterprise agent security.
Machine-payable: the API speaks the x402 pattern — HTTP 402 with a payment requirement when quota is met (settlement providers: LemonCake fiat / x402 USDC on request).
