Polymarket event detail
One Polymarket event with every market: per market the question, outcomes with prices and token ids, volume (total, 24 h, 1 w, 1 m, 1 y), liquidity, best bid/ask, spread, last trade price, price changes, tick size, dates and resolution status; plus the event's description, tags, series, volume, liquidity and open interest.
Every response includes credits_used: the credits this call cost.

slug | string | Event slug as in polymarket.com/event/<slug>. Example: presidential-election-winner-2024 |

Every endpoint also takes fresh, raw, fields (see lean responses and caching).
Example
curl "https://api.api.sh/polymarket/v1/event?slug=presidential-election-winner-2024" \
-H "x-api-key: $APISH_KEY" import os, requests
res = requests.get(
"https://api.api.sh/polymarket/v1/event",
params={"slug": "presidential-election-winner-2024"},
headers={"x-api-key": os.environ["APISH_KEY"]},
timeout=120,
)
res.raise_for_status()
data = res.json() const url = new URL("https://api.api.sh/polymarket/v1/event");
url.searchParams.set("slug", "presidential-election-winner-2024");
const res = await fetch(url, { headers: { "x-api-key": process.env.APISH_KEY } });
if (!res.ok) throw new Error(`${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).
