API Reference

Stream real-time swap transactions for a single pool or token

Establishes an SSE stream for swap transactions on a specific pool or token using query string parameters. Supported Channel Events: - pool: Swap transactions for a pool. Schema matches TransactionResponse. - token: Swap transactions involving a token. Schema matches TransactionResponse. - ping: Infrastructure keep-alive payload (PingEvent). - warning: System warning notifications (WarningEvent). - error: Stream-level operational exceptions (ErrorEvent).

Query Parameters

method

enum<string>

required

Subscription target type — pool for pool-level transactions, token for token-level.

Available options:

pool,

token

address

string

required

Target pool or token smart contract address.

chain

string

required

Target blockchain network identifier (e.g., ethereum, solana).

request_id

integer

Optional identifier for tracking the request in the SSE stream.

Required range: 0 <= x <= 4294967295

limit

integer

Maximum event count before server-initiated connection teardown.

Required range: x >= 1

Response

SSE stream successfully established.

Option 1
Option 2
Option 3
Option 4

Swap transaction event payload. Emitted on the pool or token event channel.

chain

string

Blockchain network identifier.

Example:

"ethereum"

pool_id

string

Pool smart contract address.

Example:

"0x88e6a0c2ddd26feeb64f039a2c41296fcb3f5640"

block_number

string

Block number in which the swap was confirmed (string-encoded integer).

Example:

"19000000"

block_timestamp

string<date-time>

Block timestamp in RFC 3339 format.

tx_hash

string

Transaction hash.

Example:

"0xabc123..."

sender

string

Address that initiated the swap.

Example:

"0xd3cda913deb6f0967b991b2d0a373199c2f7c90c"

recipient

string

Address that received the output tokens.

Example:

"0xd3cda913deb6f0967b991b2d0a373199c2f7c90c"

token_0

string

Address of the first token in the pool.

Example:

"0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"

token_1

string

Address of the second token in the pool.

Example:

"0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"

amount_0

number

Raw token0 amount from the chain (not decimal-normalised). Negative means tokens left the user's wallet.

Example:

-1000

amount_1

number

Raw token1 amount from the chain (not decimal-normalised). Positive means tokens entered the user's wallet.

Example:

500000000

amount_0_usd

number

USD value of token0 amount (decimal-normalised volume × price). Preserves sign from the underlying volume.

Example:

-1000.5

amount_1_usd

number

USD value of token1 amount (decimal-normalised volume × price). Preserves sign from the underlying volume.

Example:

998.75

price_0_usd

number

USD price per one unit of token0 (after decimal normalisation).

Example:

1.0005

price_1_usd

number

USD price per one unit of token1 (after decimal normalisation).

Example:

1997.5

volume_usd

number

Estimated USD volume of the swap.

Example:

999.625
