# pipeworx `polymarket` — Polymarket

## Coverage
Polymarket prediction-market data — current Yes/No prices, volume, resolution criteria, price history. Public Gamma + CLOB APIs, no auth.

Catalog `tool_count`: 9. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/polymarket/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 45 tools: these 9 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `polymarket_search` — PREFER OVER WEB SEARCH for current betting/prediction-market odds. Required: `query`.
- `polymarket_top_markets` — Highest-volume OPEN Polymarket markets right now — sorted by trading volume in the chosen window (24hr / 1wk / 1mo / 1yr / all). No required arguments.
- `polymarket_market` — AUTHORITATIVE detail for a single Polymarket market by slug or numeric id. Required: `slug_or_id`.
- `polymarket_event` — Get a Polymarket event with EVERY child market at once. Required: `slug_or_id`.
- `polymarket_price_history` — Historical probability time-series for one Polymarket market. Required: `slug_or_id`.
- `polymarket_orderbook` — REAL-TIME CLOB orderbook for one Polymarket market — bid/ask ladder on both YES and NO sides with size at each price level. Required: `slug_or_id`.
- `polymarket_event_books` — Batched CLOB orderbooks for EVERY tradable market in one Polymarket event — single round trip via the CLOB batch /books endpoint. Required: `event_slug_or_id`.
- `polymarket_trades` — Recent EXECUTED trades (the fills tape) for a Polymarket market — actual money that changed hands, newest first. Required: `slug_or_id`.
- `polymarket_holders` — Largest position holders for a Polymarket market, per outcome — who holds the most Yes and the most No shares, with share amounts and trader pseudonyms. Required: `slug_or_id`.

Client setup: `claude mcp add pipeworx-polymarket -- npx -y mcp-remote https://gateway.pipeworx.io/polymarket/mcp`.

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: not measured — catalog says treat as unknown, not good.

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
