00 / SURFACES

Three ways in.

Pick the surface that matches your agent's appetite. The first two are public. The third needs a key but unlocks the live data feed.

00.01

llms.txt Public

A curated index of every page agents care about. Drop it into your system prompt for instant context, or let a crawler ingest /llms-full.txt for the concatenated body.

/llms.txt /llms-full.txt

00.02

Markdown views Public

Append .md to any page URL for clean, LLM‑ready markdown. No HTML parsing, no chrome, just the data your model can reason about.

/arbs.md /calendar.md /movers.md /volume.md

00.03

MCP server Key required

Streamable HTTP at predradar.com/mcp. Six tools, two resources, per‑key rate limits, free and Pro tiers. Live data, sub‑second latency, no SDK to install.

05 / FAQ

Questions, answered.

Q.01

Do I need an API key for llms.txt or .md pages?

No. Both /llms.txt and every .md page variant are fully public, no authentication required. Only the MCP server needs a key.

Q.02

What is the rate limit on the free tier?

100 requests per day, with a burst cap of 10 per minute. Free‑tier responses are served from a 60‑second cache so typical queries still feel fast.

Q.03

Where do I get an API key?

Sign up at /signup with your email. We send a magic link, no password needed. Keys are issued instantly on the account page.

Q.04

What MCP clients work with PredRadar?

Claude Desktop, Cursor, Cline, and any client that supports the Streamable HTTP MCP transport. The endpoint is a plain HTTPS URL, so integration is straightforward.

Q.05

Can I redistribute the data my agent fetches?

Aggregated insights and derivative analysis are fine. Bulk redistribution of raw market data is not. See terms for the full policy.
