Predictable paths for agents and tools.

Vercel developer resources

• OpenAPI spec — typed API contract with operation IDs, request schemas, response schemas, and rate-limit headers.
• llms.txt — agent guidance, use cases, limitations, and canonical links.
• sitemap.xml — indexable URL inventory with last modification dates.
• MCP manifest — read-only Streamable HTTP metadata.
• Versioned MCP endpoint — canonical JSON-RPC tools for public portfolio and project discovery.

Named project resources

Use the case studies when you need evidence about a named product or implementation context. Each project has a stable case-study route and a linked live preview where available:

• CashLift — Personal product · Read-only demo; live preview.
• MyDears — Synthetic prototype · Human review; live preview.
• DevBrief — Personal experiment · In progress; live preview.

These previews are hosted on Vercel. They are not a public API, OpenAPI document, authentication flow, or webhook service.

API versioning and rate limits

PaRi Portfolio is deployed on Vercel. The canonical read-only MCP API is /api/v1/mcp. The unversioned /api/mcp path remains a compatibility alias and sends RFC 9745 Deprecation and successor Link headers.

API responses publish RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, and RateLimit-Policy for a 60-request, 60-second advisory window. Clients receiving 429 should honor Retry-After. The MCP endpoint is intentionally read-only and only describes public portfolio content. For identity and contact verification, use the about page, contact page, and privacy page.
