The Koios calls this client makes.

The Koios endpoint name of a call, as in its path.

Whether a request reads or submits.

HTTP method of a request.

Request body.

One Koios request, before paging. A paged request names the order its rows are read in; the client adds offset and limit.

tip: the chain tip.

address_utxos, extended, ordered by output reference.

asset_utxos, extended, ordered by output reference.

asset_txs with history: every transaction that included the asset. Koios lists them newest first; pages are read by block height then transaction id only so that pages are stable. That order is not the order in which the asset was passed on: Koios gives no index within a block, and a transaction that included the asset need not have spent it.

tx_info with inputs, assets, scripts and bytecode. Without _assets Koios answers every asset list empty.

tx_cbor: the raw transactions.

epoch_params of one epoch.

cli_protocol_params: the current protocol parameters in the node's own JSON form.

submittx: submit a signed transaction's CBOR.

tx_status: confirmations of transactions.

account_info of one stake address.

reference_script_utxos: every unspent output whose reference script is one of the hashes, ordered by output reference. Koios names each row's hash; a consumer computes it from the output instead.

utxo_info: whether each named output is spent.

asset_info of one asset: its latest minting transaction and supply.

The chain tip.

One transaction that included an asset.

One transaction's resolved outputs: the outputs it spent, the outputs it referenced and the outputs it created, each with its output reference, and whether it is valid.

One transaction's raw bytes, decoded as a Conway transaction whose id is the one Koios named.

One transaction's confirmations, or Nothing when not yet seen.

One stake address's registration status, as Koios states it.

One named output and whether Koios reports it spent.

One asset's latest minting transaction and its current total supply, as asset_info states them.

An answer that does not decode, with the position that failed.

Parse an answer body as one JSON document. A body that is not one, such as a body cut off mid-array, fails with the parser's reason.

Decode a tip answer: empty when Koios returned no row. Koios API 1.4.2, cardano-community/koios-artifacts revision 2e2eb57933e1e2528de5ca36ee961759841cf389, specsresultskoiosapi-preprod.yaml: #componentsschemastipitemspropertiesblock_time refers to #componentsschemasblocksitemspropertiesblock_time, UNIX seconds. Missing, fractional, negative or overflowing raw seconds refuse by name.

Decode the rows of an address_utxos or asset_utxos page.

Decode the rows of an asset_txs page.

Decode a tx_info answer. The same pinned schema's #componentsschemastx_infoitemspropertiesblock_height refers to #componentsschemasblocksitemspropertiesblock_height, a block height.

Decode a tx_cbor answer, each transaction checked against its id.

Decode an epoch_params answer: empty when Koios returned no row.

Decode a cli_protocol_params answer with the ledger's own reader.

Decode the transaction id a submittx accepted: a JSON string, or the bare hex text.

Decode a tx_status answer.

Decode an account_info answer.

Decode a reference_script_utxos page: each row's hash and reference.

Decode a utxo_info answer.

Decode an asset_info answer.

The bech32 rendering of a Shelley address.

Parse a bech32 address.

The bech32 stake address of a reward account.

Parse a bech32 stake address.

Hex of a transaction id.

Hex of a policy id.

Hex of an asset name.
