How to use

HTTP API (Standby — recommended)

Base URL: https://synthetic-ia--coingecko-crypto.apify.actor with header Authorization: Bearer <APIFY_TOKEN>.

Endpoint	Body	Does
POST /price	{ ids: "bitcoin,ethereum", currencies?: "usd,eur" }	Prices + market cap + 24h change
POST /markets	{ currency?: usd, ids?, perPage?: 1-250, page? }	Ranked market table
POST /chart	{ id: "bitcoin", days?: 1-3650 | max, currency? }	Historical prices

GET /	—	Endpoint list

GET /price?ids=bitcoin,ethereum also works (query-string form).

# Prices for several coins
curl -X POST ".../price" -H "Authorization: Bearer $APIFY_TOKEN" \
  -d '{"ids":["bitcoin","ethereum","solana"],"currencies":"usd,eur"}'

# Top 50 coins by market cap
curl -X POST ".../markets" -H "Authorization: Bearer $APIFY_TOKEN" -d '{"currency":"usd","perPage":50}'

# 30-day chart
curl -X POST ".../chart" -H "Authorization: Bearer $APIFY_TOKEN" -d '{"id":"bitcoin","days":30}'

FAQ

Do I need a key? No. We wrap CoinGecko's public API for you.

How many coins? Thousands — pass CoinGecko coin ids (e.g. bitcoin, not BTC). Use /search to find an id from a name or symbol.

Rate limits? The upstream free API is rate-limited by IP; the Actor retries transient limits, but very high volume may need caching on your side.
