What you’ll build: Scripts that fetch and display trade history from Bebop.Time required: 5 minutesPrerequisites: None for public wallet lookups. To fetch trades attributed to your own integration, authenticate with your API key.
1. Look up trades for a wallet
Retrieve all trades for a given wallet address. The API returns trades across all Bebop-supported chains in a single response.GET /history/v2/trades
| Parameter | Required | Type | Description |
|---|---|---|---|
wallet_address | Yes | string | Wallet address to look up |
start | No | integer | Start of time range (UNIX timestamp in nanoseconds) |
end | No | integer | End of time range (UNIX timestamp in nanoseconds) |
size | No | integer | Maximum number of trade objects to return |
NOW_NS=$(date +%s)000000000
THIRTY_DAYS_NS=$((30 * 24 * 60 * 60))000000000
START_NS=$((NOW_NS - THIRTY_DAYS_NS))

12M | One token in, multiple tokens out (exact amounts per token) |
M21 | Multiple tokens in, one token out (exact amounts per token) |

Filtering by time range
Narrow results to a specific window usingstart and end parameters.
Timestamps are in nanoseconds, not seconds or milliseconds. For example,
1680303600000000000 corresponds to 2023-03-31T21:00:00Z. Passing a millisecond timestamp will return no results.import time
import httpx
# Last 30 days
now_ns = int(time.time() * 1_000_000_000)
thirty_days_ns = 30 * 24 * 60 * 60 * 1_000_000_000
resp = httpx.get(
"https://api.bebop.xyz/history/v2/trades",
params={
"wallet_address": "0xcaBD7845e4E51069E87a62d0A29064782134124C",
"start": now_ns - thirty_days_ns,
"end": now_ns,
"size": 100,
},
)
data = resp.json()
print(f'Fetched {len(data.get("results", []))} trades in last 30 days')
Pagination
IfnextAvailableTimestamp is not null, repeat the request using that value as your new end parameter:
import time
import httpx
now_ns = int(time.time() * 1_000_000_000)
thirty_days_ns = 30 * 24 * 60 * 60 * 1_000_000_000
all_trades = []
end = now_ns
while True:
resp = httpx.get(
"https://api.bebop.xyz/history/v2/trades",
params={
"wallet_address": "0xcaBD7845e4E51069E87a62d0A29064782134124C",
"start": now_ns - thirty_days_ns,
"end": end,
"size": 100,
},
)
data = resp.json()
all_trades.extend(data.get("results", []))
next_ts = data.get("nextAvailableTimestamp")
if next_ts is None:
break
end = next_ts
print(f"Fetched {len(all_trades)} trades")
2. Look up a specific transaction
Retrieve details for a single transaction hash. The API searches across all chains automatically.GET /history/v2/tx/{tx_hash}
| Parameter | Required | Type | Description |
|---|---|---|---|
tx_hash | Yes | string | Transaction hash (66-character hex string starting with 0x) |
curl "https://api.bebop.xyz/history/v2/tx/0x8f4adfc8aa60711c464194a2d297f823e7f54fadc3995ea1844d6731fdaf38ee"

tx_hash = "0x8f4adfc8aa60711c464194a2d297f823e7f54fadc3995ea1844d6731fdaf38ee"
resp = httpx.get(f"https://api.bebop.xyz/history/v2/tx/{tx_hash}")
data = resp.json()
# The response wraps results in a list
results = data.get("results", [data])
trade = results[0] if results else data
sell = (
list(trade.get("sellTokens", {}).values())[0] if trade.get("sellTokens") else {}
)
buy = list(trade.get("buyTokens", {}).values())[0] if trade.get("buyTokens") else {}
print(
f'Chain {trade.get("chain_id", "?")}: {sell.get("symbol", "?")} -> {buy.get("symbol", "?")}'
)
print(
f'Volume: ${trade.get("volumeUsd", 0):.2f} Gas: ${trade.get("gasFeeUsd", 0):.4f}'
