{"ok":true,"host":"lavarnd.up.railway.app","status":"ready","manifest":{"positioning":"This host serves agents and applications that need unpredictable, hardware-sourced random values rather than software PRNG outputs. It is distinct from deterministic hash services because its outputs are derived from physical lava lamp pixel data, making them non-reproducible. It covers three use cases: measuring entropy quality, generating a ready-to-use password, and obtaining a random hash string for seeding or nonce purposes.","host_overview":"lavarnd.up.railway.app provides hardware-derived entropy and randomness primitives sourced from live lava lamp image pixel sampling. It exposes four endpoints: an entropy quality metric, a random password generator, and two random hash outputs (SHA3-256 and SHA256). All outputs are single-shot, pay-per-call, and require no input parameters.","routing_guidance":"Use this host when an agent requires non-deterministic, hardware-sourced random values — entropy scores, random hashes, or a single strong password — and software PRNG outputs are insufficient or undesirable. Do not use it for hashing caller-supplied data (use a standard cryptographic library instead), for bulk or streaming random number generation (this is single-shot per call), for passwords with custom length or charset requirements, or for cryptographic key generation where full entropy provenance audit trails are required. If high-throughput randomness is needed, a dedicated CSPRNG service or HSM-backed API is more appropriate.","capability_clusters":[{"skill_names":["fetch-lava-entropy-score"],"cluster_name":"Entropy Quality Measurement","cluster_summary":"Provides a quantitative measure of randomness quality by computing Shannon entropy over sampled lava lamp pixels, useful for auditing entropy sources or gating cryptographic operations."},{"skill_names":["fetch-lava-sha256-entropy","fetch-lava-sha3-256"],"cluster_name":"Hardware-Derived Random Hashes","cluster_summary":"Returns unpredictable hash strings (SHA256 or SHA3-256) sourced from physical lava lamp pixel sampling, suitable as random seeds, nonces, or entropy strings."},{"skill_names":["fetch-lava-password"],"cluster_name":"Random Password Generation","cluster_summary":"Generates a single 16-character high-entropy password derived from lava lamp pixel randomness, returning the password, its length, and the character set used."}],"cross_skill_workflows":[{"steps":[{"skill_name":"fetch-lava-entropy-score","description":"Measure current entropy quality; proceed only if the returned entropy score meets the agent's minimum threshold."},{"skill_name":"fetch-lava-sha3-256","description":"Retrieve a hardware-derived SHA3-256 hash to use as a seed or nonce, now that entropy quality has been confirmed."}],"when_to_use":"Use when an agent needs to verify that hardware entropy quality is sufficient before consuming a random hash as a seed or nonce.","workflow_name":"Entropy-Gated Seed Acquisition"},{"steps":[{"skill_name":"fetch-lava-entropy-score","description":"Check that the current entropy score is above an acceptable threshold before generating a password."},{"skill_name":"fetch-lava-password","description":"Generate a 16-character password from lava lamp entropy, confident that the underlying randomness quality is adequate."}],"when_to_use":"Use when an agent needs to confirm randomness quality before issuing a hardware-derived password to a user or system.","workflow_name":"Entropy-Gated Password Generation"}]},"model":"claude-sonnet-4-6","version_no":4,"generated_at":"2026-05-18T07:25:08.518Z","provenance":"ai_authored_unreviewed","ai_authored":true,"merchant_reviewed":false,"merchant_edited":false,"merchant_reviewed_at":null,"merchant_edited_at":null,"skill_md_url":"https://x402gle.com/servers/lavarnd.up.railway.app/SKILL.md","skills_url":"https://x402gle.com/servers/lavarnd.up.railway.app/skills.json"}
