X-API-Key

string

header

required

Preferred for swaps-api endpoints (/swaps/*, /stats/*, /trending, /pool-events).

Path Parameters

signature

string

required

Response

Swap event

A single swap event from the raw swaps index. Same shape across /swaps, /swaps/range, /swaps/whale, /swaps/{signature}, /swaps/trader/{wallet}, /swaps/token/{mint}.

Note that the streaming feeds (WebSocket and gRPC) use a different shape — see WebSocket wire format — most notably swap_type (string) vs is_buy (bool) here, and dex as the string name vs dex as the integer ID here.

signature

string

Solana transaction signature (base58).

slot

integer<int64>

timestamp

integer<int64>

Unix epoch milliseconds.

token_address

string

Non-SOL side of the pool (the token being bought/sold).

pair_address

string

On-chain pool/LP account.

user

string

Trader wallet.

is_buy

boolean

true if SOL → token; false if token → SOL.

dex

enum<integer>

Integer DEX identifier used in raw swap rows. Mapping:

ID	DEX
1	`pumpfun`
2	`pumpswap`
3	`raydium_amm`
4	`raydium_clmm`
5	`raydium_cpmm`
6	`orca`
7	`meteora_damm_v2`
8	`meteora_dbc`
9	`meteora_dlmm`
10	`meteora_pools`

sol_amount

integer<int64>

Lamports (1 SOL = 1e9).

token_amount

integer<int64>

Token base units; divide by 10**quote_decimals for human-readable.

fee

integer<int64>

LP fee paid, in lamports.

fee_bps

integer

Effective LP fee, in basis points.

creator_fee

integer<int64>

Decimals of the base (SOL) side — typically 9.

quote_decimals

integer

Decimals of the quote (token) side.

virtual_sol_reserves

integer<int64>

Virtual SOL reserves (pump.fun bonding curve). 0 on non-pump pools.

virtual_token_reserves

integer<int64>

real_sol_reserves

integer<int64>

Actual reserves on the pool after the swap.

real_token_reserves
