Common questions

Is Prediction Market Friction Tracker safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Prediction market friction tracker

Structured KYC, fee, and withdrawal data across 12 prediction-market venues, plus a change feed for when those terms move and a natural-language "which venue is best for X" recommendation tool. Built for AI agents that need to check execution friction before routing a trade — not for humans clicking around a dashboard.

Live now: https://prediction-friction-tracker-production.up.railway.app

For agents: three ways in

Plain HTTP — GET /friction/venues, GET /friction/venue/{slug}, GET /friction/changes?since= . Full OpenAPI spec at /openapi.json, interactive docs at /docs, agent-readable summary at /llms.txt.
MCP — a streamable-HTTP MCP server mounted at /mcp/, exposing list_venues, get_venue, recommend_venue, and get_changes_info as tools. Point any MCP-compatible client at the /mcp/ URL directly.
x402 — /friction/changes (the time-sensitive change feed) is gated by the x402 protocol: unpaid requests get a real 402 with a payment challenge; pay $0.05 USDC on Base mainnet and retry to get the data. This is live, verified end-to-end with real money, not a demo — see api.py for the CDP-facilitator wiring.

Endpoints

Endpoint	Cost	What it returns
`GET /friction/venues`	Free	Current snapshot of every tracked venue. Optional `?confidence=verified\	stale\	unconfirmed` filter.
`GET /friction/venue/{slug}`	Free	One venue's current fee/KYC/withdrawal/API-access data, e.g. `/friction/venue/kalshi`.
`GET /friction/changes?since=`	$0.05 USDC (x402)	Append-only log of every detected change since a timestamp — the time-sensitive product.

Every record carries a confidence field: verified (spot-checked or high-confidence extraction), stale (source was unreachable, showing a cached value), or unconfirmed (LLM extraction was ambiguous). Treat unconfirmed as a lead to verify against the venue directly, not a fact to trade on.

MCP tools

list_venues(confidence) — browse/filter the current snapshot.
get_venue(slug) — one venue's full data.
recommend_venue(query) — free-text "which venue is best for lowest fees on high-frequency trading" / "I don't want to do KYC" / "API access without a wallet" style questions, reasoned over the current dataset. Says so explicitly rather than guessing when a query depends on data this tracker doesn't have (liquidity, volume, spread, uptime).
get_changes_info() — describes the paid change feed (URL, price) without reimplementing it for free.

What's here

File	What it does
`schema.py`	The data model — one `VenueFriction` record per venue, plus the `VenueRecommendation` response shape
`venues.py`	The 12 tracked venues and their policy-page source URLs
`scrapers/base.py`	Fetches and cleans raw policy-page text (requests + Playwright fallback for JS-rendered pages)
`extract.py`	Sends raw page text to Claude, gets back a structured `VenueFriction` matching the schema
`recommend.py`	Natural-language venue recommendation — reasons over the current dataset via Claude, structured-output constrained to real venue slugs
`reference_check.py`	Cross-checks scraped fees against a third-party source (TradeBlock), flags divergences for human review
`storage.py`	SQLite: `current_state` table (latest snapshot) + `change_log` table (append-only, the paid product)
`diff.py`	Compares a fresh extraction to the stored one, writes a `ChangeEvent` for anything that moved
`run_pipeline.py`	Orchestrates fetch → extract → diff → store, for all 12 venues
`api.py`	FastAPI server — the HTTP endpoints above, x402 payment gating, MCP mount
`mcp_server.py`	The MCP tool definitions, mounted into `api.py` at `/mcp/`
`test_pipeline_logic.py`, `test_recommend_logic.py`	Pure-logic tests, no API key needed

Running it locally

pip install -r requirements.txt

python test_pipeline_logic.py # no API key needed, proves storage/diff logic python test_recommend_logic.py # no API key needed, proves recommendation logic export ANTHROPIC_API_KEY=sk-ant-... python run_pipeline.py # real scrape -> extract -> store, all 12 venues uvicorn api:app --reload # boots the API on localhost:8000

Then in another terminal:

curl http://localhost:8000/friction/venues

curl http://localhost:8000/friction/venue/kalshi curl "http://localhost:8000/friction/changes?since=2020-01-01T00:00:00Z"

See CLAUDE.md for environment quirks, Claude API usage notes, and the data-quality/confidence model in more depth.

Informational only — not financial or legal advice. Verify directly with the venue before acting on any figure returned here.
