Pitch

Dayze is a pay-per-call people + life-in-days API for AI agents — notable packs with day-of-life numbers, similar people, and birthday peers. Public notable_* tools need no API key; USDC on Base via x402 after the free tier.

Quick try

# Streamable HTTP (JSON-RPC)
curl -X POST https://dayze.com/api/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"curl","version":"1.0"}}}'

curl -X POST https://dayze.com/api/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'

# REST (compat)
curl https://dayze.com/api/v1/mcp

curl -X POST https://dayze.com/api/v1/mcp \
  -H 'Content-Type: application/json' \
  -d '{"tool":"notable_pack","parameters":{"slug":"albert-einstein"}}'

Timeline events include day_number (e.g. Einstein’s Nobel = Day 15,580).

Auth

• Public notable_* tools: no login (x402 after free tier)
• Private life-graph tools: Bearer dayze_k_… or OAuth dayze_at_…
• OAuth 2.1 + PKCE + DCR for Claude / ChatGPT / Gemini agents — see https://dayze.com/docs/agents

Transport

• Streamable HTTP JSON-RPC at /api/mcp (initialize, tools/list, tools/call)
• REST MCP-compatible at /api/v1/mcp (GET capabilities, POST {tool, parameters})
• GET SSE on /api/mcp is stubbed (405) on Netlify serverless
