Extrinsics Feed By Network

Last updated

GET
/api/v1/{network}/extrinsics

Network-addressed form of the route above. mainnet/finney return the same data as the unprefixed path; testnet/test return testnet data.

Path Parameters

network*string

Network to address. mainnet and finney are the same network, as are testnet and test.

Value in

  • "finney"
  • "mainnet"
  • "test"
  • "testnet"

Query Parameters

limit?integer

Maximum number of rows to return in one page (at most 100). Routes differ in how they handle a larger value: some reject it with 400 invalid_query, others clamp to the maximum and answer 200. Read the limit echoed in the response body rather than assuming the page is the size you asked for.

Range1 <= value <= 100
offset?integer

Number of rows to skip before the page begins. Correct only in combination with the page size the response actually returned -- prefer cursor for anything beyond the first few pages, since a row inserted mid-scan shifts every later offset.

Range0 <= value
cursor?string

Opaque keyset pagination token. Echo the next_cursor from the previous response back VERBATIM -- it encodes an internal sort position, not a row number, so it must never be constructed, incremented, parsed or compared. Omit it for the first page; a response with no next_cursor is the last page.

block?integer
Range0 <= value
signer?string
call_module?string
call_function?string
call_hash?string

Requires call_module so the decoded call-args JSON scan stays scoped.

Match^0x[0-9a-fA-F]{64}$
success?string

Value in

  • "true"
  • "false"
block_start?integer
Range0 <= value
block_end?integer
Range0 <= value
from?integer
Range0 <= value
to?integer
Range0 <= value
format?string

Response format override. Use csv to download the route rows as text/csv; json keeps the default response envelope.

Value in

  • "json"
  • "csv"
