Polymarket market detail

One Polymarket market: question, description and resolution source, outcomes with prices and token ids, volume, liquidity, open interest, best bid/ask, spread, last trade price, 1 h/24 h/1 w/1 m price change, tick size, minimum order, dates and resolution status. book=1 adds the live order book (bids and asks) of each outcome for open markets; holders=true adds each outcome's top holders.

Every response includes credits_used: the credits this call cost.

Parameters

Every endpoint also takes fresh, raw, fields (see lean responses and caching).

Example

curl "https://api.api.sh/polymarket/v1/market?slug=will-donald-trump-win-the-2024-us-presidential-election" \
  -H "x-api-key: $APISH_KEY"

import os, requests

res = requests.get(
    "https://api.api.sh/polymarket/v1/market",
    params={"slug": "will-donald-trump-win-the-2024-us-presidential-election"},
    headers={"x-api-key": os.environ["APISH_KEY"]},
    timeout=120,
)
res.raise_for_status()
data = res.json()

const url = new URL("https://api.api.sh/polymarket/v1/market");
url.searchParams.set("slug", "will-donald-trump-win-the-2024-us-presidential-election");

const res = await fetch(url, { headers: { "x-api-key": process.env.APISH_KEY } });
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const data = await res.json();

Response

A JSON object with the fields described above, plus raw (the source's own data), cached, fetched_at and credits_used. Errors return {"success": false, "error": "…"} with the HTTP status (see errors). A lookup that ran but found nothing (404) costs the price above; refused calls and errors on our side are free (what's charged).
