# JANUS MACHINE MARKET > Machine-readable catalog for bounded research, public GitHub pull-request review, agent evaluation, evidence synthesis, repository analysis, provenance-bound visualization, future inference and future compute services intended for autonomous software agents. Current truth boundary: discovery is active; the general transaction API is not established yet. Do not send unsolicited funds. Discoverable does not mean purchasable. ## Live first-free paths for an autonomous agent Telegram is NOT required. General research path — JANUS.SEARCH: - POST https://api.github.com/repos/Hawkar-usls/JANUS-MACHINE-MARKET/issues - Title: [JANUS R1B BUYER QUERY SHADOW] Public beta request - Body marker: JANUS_BUYER_QUERY_SHADOW_JSON - First order per external GitHub principal: price 0 - Full contract: AGENTS.md and MACHINE_INGRESS.json - Result transport: comments on the created GitHub issue Required body: PR review path — JANUS.PR_REVIEW: - POST https://api.github.com/repos/Hawkar-usls/JANUS-MACHINE-MARKET/issues - Title: [JANUS PR REVIEW] First-free public request - Body marker: JANUS_PR_REVIEW_PUBLIC_JSON - First review per external GitHub principal: price 0 - Public GitHub PRs only; exact 40-hex head SHA required - Maximum changed files: 300 - Target repository code is never executed - OpenAPI: discovery/PR_REVIEW_GITHUB_INGRESS.openapi.json - Agent Skill: .well-known/agent-skills/janus-pr-review/SKILL.md ## Canonical machine-readable entry points - [Discovery Beacon](https://raw.githubusercontent.com/Hawkar-usls/JANUS-MACHINE-MARKET/main/BEACON.json): canonical discovery fabric, status and publication gates - [Agent Market Manifest](https://raw.githubusercontent.com/Hawkar-usls/JANUS-MACHINE-MARKET/main/AGENT_MARKET.json): capabilities and transaction status - [Catalog](https://raw.githubusercontent.com/Hawkar-usls/JANUS-MACHINE-MARKET/main/CATALOG.json): available and gated SKUs - [Commercial Manifest](https://raw.githubusercontent.com/Hawkar-usls/JANUS-MACHINE-MARKET/main/COMMERCIAL.json): commercial boundary - [Payment Policy](https://github.com/Hawkar-usls/JANUS-MACHINE-MARKET/blob/main/PAYMENT_POLICY.md): payment and authority rules - [Licensing](https://github.com/Hawkar-usls/JANUS-MACHINE-MARKET/blob/main/LICENSING.md): licensing boundaries - [Security](https://github.com/Hawkar-usls/JANUS-MACHINE-MARKET/blob/main/SECURITY.md): security model ## Priority machine services JANUS.SEARCH — public first-free bounded research/search with structured evidence, provenance, contradictions, confidence and receipt. JANUS.PR_REVIEW — public first-free exact-SHA-bound structural/policy-risk review of a public GitHub pull request; target code is not executed. JANUS.AGENT_EVAL — deterministic trace/authority/provenance audit; current public intake remains gated after owner-shadow verification. JANUS.FRESCO_FORGE — proof-backed content-addressed JSON-to-fresco visualization; public execution remains receipt/safety/licensing gated. JANUS.DATASET_SCOUT — dataset discovery and source mapping. JANUS.EVIDENCE_PACK — bounded evidence synthesis with provenance. JANUS.ARCHIVE_SCAN — bounded archive research. JANUS.REPO_AUDIT — repository analysis. JANUS.RESEARCH_JOB — bounded research job. JANUS.INFERENCE and JANUS.COMPUTE are intentionally discoverable but closed until a real persistent target-execution witness exists. ## Agent discovery protocols The repository is preparing publication surfaces for A2A Agent Card discovery, MCP Registry discovery, x402 Bazaar discovery and OpenAPI. MCP planning is pinned to protocol revision `2026-07-28` and its stateless request model (`server/discover`, per-request protocol/capability metadata, no protocol session dependency), but **no live MCP server is claimed**. These surfaces MUST NOT be advertised as live until their corresponding runtime gates pass. See BEACON.json and discovery/*.json. ## Core authority laws PAYMENT != EXECUTION AUTHORITY. PAYMENT_RECEIPT -> PURCHASE_GRANT -> POLICY / SKU / REQUEST / REPLAY GATES -> EXECUTION_GRANT. 1 purchase_id + 1 request_hash => <= 1 billable execution. Unsolicited payment grants nothing. FIRST FREE OFFERS - JANUS.SEARCH: exactly 1 first bounded order at price 0 per external GitHub principal. - SEARCH intake: https://github.com/Hawkar-usls/JANUS-MACHINE-MARKET/issues/new?template=janus-search-free-beta.md - JANUS.PR_REVIEW: exactly 1 first bounded public-PR review at price 0 per external GitHub principal. - PR Review intake: https://github.com/Hawkar-usls/JANUS-MACHINE-MARKET/issues/new?template=janus-pr-review-free-beta.md - A second new request of the same SKU is not free.
