Export Chain Events
Last updated
Fetch up to 25,000 chain events in one call -- the same rows, filters and ordering as /api/v1/chain-events, without the 100-row page ceiling or the cursor bookkeeping that comes with it. ?pallet / ?method narrow by event id; ?before reads down from a block number, which is how a caller walks a large range in deliberate chunks; ?limit caps the call (<=25000, default 5000). REQUIRES PAYMENT: this route answers 402 with an x402 quote when no payment is presented, on Base or Solana -- see /.well-known/x402. It is the one family that does; every other route on this API serves an unpaid caller normally. Served live, no static file.
Query Parameters
Filter to events emitted by this pallet, e.g. SubtensorModule or Balances.
length <= 64Filter to events with this method name within the pallet, e.g. StakeAdded.
length <= 64Inclusive first block height of the range to read. Omit for an unbounded end. Must not be later than the range's upper bound.
0 <= valueMaximum number of rows to return in one page (at most 25000). A larger value, or a non-positive one, is rejected with 400 invalid_query -- so a short page means the result set is exhausted, not that the server quietly capped you (#9916). Omitted, the server applies 5000.
