Replay a slot

GET/v1/replay/slot/{slot}🔑 API key required

Replay a historical block (“à un moment donné”) from the Ferno archive: every decoded swap in the slot, optionally filtered to one mint with ?mint=. Premium: requires a Scale or Enterprise plan.

Path parameters

Field	Type	Description
`slot`required	number	The slot to replay.

Query parameters

Field	Type	Description
`mint`optional	string	Filter to swaps that touch this mint (base or quote).

Response fields

Field	Type	Description
`slot / blockTime`	number	The block and its time.
`txCount`	number	Transactions in the block.
`swapCount / truncated`	number / boolean	Decoded swaps returned (capped at 1000).
`swaps[].signature`	string	The tx the swap came from (replay it with /replay/tx/:sig).
`swaps[].dex / side / baseMint / quoteMint / baseAmount / quoteAmount / poolAddress / signer`	string / number	Each decoded swap.

Premium (Scale+). The Ferno archive trails the chain head by ~26 days and has a finite depth, so very recent or very old slots may return slot_not_found. The ~8 MB block fetch is the main cost.
