Chain data API

A read-only, public API indexing the whole chain. This is a Blockscout v2 instance, so if you have used Blockscout elsewhere the shapes will be familiar.

Base URL: https://api.testnet.kriptonyx.com/api/v2

No authentication, no key.

Endpoints

Chain

Endpoint	Returns
GET /stats	Totals — blocks, transactions, addresses, gas prices
GET /search?q=	Blocks, transactions, addresses and tokens by term

Blocks

Endpoint	Returns
GET /blocks	Recent blocks, paginated
GET /blocks/{number_or_hash}	One block
GET /blocks/{number_or_hash}/transactions	Its transactions

Transactions

Endpoint	Returns
GET /transactions	Recent transactions, paginated
GET /transactions/{hash}	One transaction
GET /transactions/{hash}/logs	Its event logs
GET /transactions/{hash}/token-transfers	Its token transfers

Addresses

Endpoint	Returns
GET /addresses/{hash}	Balance, contract flag, metadata
GET /addresses/{hash}/transactions	Transaction history
GET /addresses/{hash}/token-balances	All token balances
GET /addresses/{hash}/logs	Logs emitted by a contract

Tokens and contracts

Endpoint	Returns
GET /tokens	Token registry
GET /tokens/{hash}	One token
GET /tokens/{hash}/holders	Holder list
GET /smart-contracts/{hash}	Verified source and ABI

Examples

curl -s https://api.testnet.kriptonyx.com/api/v2/stats

{ "total_blocks": "6181577", "total_transactions": "415", "total_addresses": "144" }

curl -s https://api.testnet.kriptonyx.com/api/v2/transactions/0x3341c2aff0d8409c62f728ea8aef00f77cec5b1c32f91257ee930034876cc075

Pagination

List endpoints return next_page_params. Pass it back as a query string to get the next page; null means the end.

const base = 'https://api.testnet.kriptonyx.com/api/v2';
let url = `${base}/addresses/${pair}/logs`;
const all = [];

while (url) {
  const body = await fetch(url).then((r) => r.json());
  all.push(...body.items);
  url = body.next_page_params
    ? `${base}/addresses/${pair}/logs?` + new URLSearchParams(body.next_page_params)
    : null;
}

Bound your loops

History is long. Stop once you have passed the block or timestamp you care about rather than walking to genesis.

Why not eth_getLogs

The node caps a single log query at 10,000 blocks, and the chain is past six million. Reading a contract's full history over JSON-RPC means hundreds of calls with careful range management. The indexer has already done this — one paginated request gives you the same data.

This is exactly how the explorer's DeFi panel derives pool volume: it reads Swap events from each pair's logs through this API.
