Self-hosted discovery surfaces
Primitive402 publishes route, schema, pricing, x402, Bazaar-style, LLM-readable, and agent-manifest metadata from the same route catalog.
How agents discover tools
Agents can inspect stable machine names, descriptions, schemas, local routes, x402 routes, prices, tags, safety notes, MCP names, and SDK methods before deciding which Primitive402 tool to call.
safe_fetch_url, check_prompt_injection_risk, verify_claim_against_source, create_page_proof, extract_return_policy, extract_subscription_terms, check_product_fitx402 and Bazaar-style readiness
Unpaid /x402/v1/* requests should return HTTP 402 Payment Required with payment metadata including network, amount, asset, payTo, resource URL, resource description, MIME type, and Bazaar extension metadata when available.
The current production public beta uses Base mainnet USDC. Marketplace discovery may require successful settlement activity through the relevant production facilitator path and may not update immediately.

Run the readiness check
pnpm discovery:check --baseUrl https://primitive402.dev
The checker verifies all self-hosted discovery files, rich agent manifest entries, local and x402 OpenAPI paths, unpaid 402 responses, resource URLs, prices, and Bazaar categories.
External indexing status
- Current: Primitive402 self-hosted discovery surfaces are live and generated from the route catalog.
- Next: verify external Bazaar or Agentic.Market-style listing requirements with provider-specific tools or APIs.
- Important: external indexing can be asynchronous and may depend on successful settlement, facilitator support, metadata ingestion rules, or provider credentials.
