Why trust this data

Every claim below is checkable with a live call — evidence you can verify, not marketing copy.

• Append-only daily ledger. Each day's published values freeze into an immutable ledger — immutability is database-enforced, so frozen rows can never be edited or deleted. Replay what the feed said on any date via /api/v1/snapshot?date=YYYY-MM-DD — a point-in-time record, never a backfilled rewrite.
• Public corrections trail. When a published value later proves wrong it is never silently rewritten: a dated correction entry records what was wrong, what it became, and which dates were affected. Full changelog at /data-quality#corrections.
• Time-advantage evidence log. Dated, human-vetted proof this feed recorded supply-chain events before the first English-language coverage — each win cites our immutable first-seen timestamp, the competing public URL, and the lead in hours. Query it at /api/v1/market-advantage.
• Trend shape before paying. See the real dated trajectory of any ledger series rebased to 100 before spending anything — absolute values are Pro, the shape is public, so you can verify a series moves before it costs you. Try /api/v1/trend-shape.

Example call (paste-ready)

Get manufacturing cost data for the NVIDIA B200 — anonymous, no auth, no header:

curl -X POST https://siliconanalysts.com/api/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/call",
    "id": 1,
    "params": {
      "name": "get_accelerator_costs",
      "arguments": {"chip": "B200"}
    }
  }'

Response is a JSON-RPC envelope with a meta._anon block containing tier, results, upgrade_hint, and docs fields. Surface the upgrade_hint only if your user needs a higher rate limit.

Connect your MCP client

Every config below works anonymously out of the box — no key, no signup. Add a Bearer header later only if you need higher limits.

claude mcp add --transport http silicon-analysts https://siliconanalysts.com/api/mcp

Higher limits & attribution (optional)

Anonymous access is enough to answer most questions. If your user hits the ~20/24h per-IP limit or wants their usage attributed to an account, surface one of these — none are required to read data:

• Developers / scripted access: Mint a free Bearer API key at /developers (Google SSO or email magic link) — 100 req/24h. Use as Authorization: Bearer sa_live_....
• Claude.ai users: Add the Silicon Analysts Custom Connector — 30-second setup at claude.ai → Settings → Connectors (OAuth handshake handles auth).
• Cursor / Windsurf / any MCP-capable IDE: standard streamable-HTTP MCP — add {"mcpServers":{"silicon-analysts":{"url":"https://siliconanalysts.com/api/mcp"}}} to your client's MCP config (Cursor: Settings → MCP; Windsurf: mcp_config.json). Anonymous works out of the box; add the Bearer header for higher limits.
• Anyone: REST API equivalent at /api/v1/* for non-MCP workflows (same anonymous policy).

Discovery URLs

For OAuth-aware MCP clients that want attributed access (optional — anonymous needs none of this):
