Firi Nordic Exchange API

healthy 4,791 Subscribers

Live order-book exchange data from Firi, the regulated Norwegian crypto venue and the largest in the Nordics, over its public API — no key, nothing stored. This is the regional venue view for the Norwegian krone (NOK) and Danish krone (DKK) order books: Nordic on-exchange price discovery, distinct from the global-aggregate and the other regional-exchange APIs in the catalogue. The ticker endpoint returns a pair full market summary — last traded price, 24h high/low, the 24h change percent, day volume and the live best bid, best ask and spread. The orderbook endpoint returns the live limit-order book — top bids and asks with cumulative depth and the bid/ask spread — so you can read on-venue liquidity. The trades endpoint returns the most recent executed trades with price, amount, side and time. The markets endpoint lists every NOK and DKK pair the venue trades with its last price and day volume. Coins traded include BTC, ETH, XRP, SOL, ADA, LTC, BNB, DOT and USDC, quoted in NOK and DKK, updated live. Build a pair from coin plus fiat (coin=btc, fiat=nok) or pass it directly (pair=ETHDKK).

Frax Finance Pools & Yield API

Live liquidity-pool and yield data for the Frax Finance ecosystem — the FRAX stablecoin, frxETH and FXS — from the public Frax API, no key, nothing stored. This is the Frax-yield view: every incentivised Frax liquidity pool across every chain and DEX, with its locked liquidity and APY, distinct from the generic DeFi-yield and protocol APIs in the catalogue. The pools endpoint lists Frax pools — optionally filtered by chain or DEX platform — with the trading pair, the pool tokens, the value locked and the base and maximum APY. The pool endpoint returns one pool in full, including the reward breakdown across swap fees and incentive rewards. The summary endpoint aggregates the ecosystem: total value locked, the pool count and the distribution across chains and DEX platforms, plus the highest-yielding pools. Build DeFi yield dashboards, Frax-farming optimisers, APY trackers and treasury tools on top of real Frax Finance data. Filter by chain (ethereum, arbitrum, fraxtal, optimism, polygon and more) or platform (uniswap_v3, curve, convex, balancer); pool APYs are returned as percentages.

Sky (MakerDAO) Savings Rate & Protocol API

Live protocol stats from Sky, the decentralized stablecoin protocol formerly known as MakerDAO and the issuer of the USDS and DAI stablecoins — no key, nothing stored. This is the Sky-protocol view: the Sky Savings Rate (SSR) and DAI Savings Rate (DSR), the value locked in savings, the SKY staking yield and the overall ecosystem size, distinct from the generic DeFi-TVL, yields and lending APIs in the catalogue. The overview endpoint returns the latest ecosystem snapshot — the Sky Savings Rate APY, the savings TVL, the SKY staking APY, the farm APY, the total reward TVL, the whole-ecosystem TVL, the wallet count and the number of savings depositors. The savings endpoint returns the current savings rates: the live SSR and DSR and the dollar value deposited in each. The history endpoint returns the savings-rate timeline — per-day SSR, DSR and deposited totals — so you can chart how the on-chain risk-free rate has moved. Build DeFi yield dashboards, stablecoin-savings widgets, rate-comparison tools and treasury bots on top of the dominant decentralized stablecoin protocol. SSR and DSR are the on-chain savings benchmarks for USDS and DAI; rates are returned as percentages.

L2BEAT Rollup Risk & TVS API

Live Ethereum layer-2 / rollup risk and value-secured data from L2BEAT — no key, nothing stored. L2BEAT's signature is its independent risk framework: every rollup is rated by maturity Stage (Stage 0 / 1 / 2) and assessed across the canonical risk dimensions — sequencer failure, state validation, data availability, exit window and proposer failure — each carrying a good / warning / bad sentiment and a plain-language explanation. This is the rollup-risk and total-value-secured (TVS) view, distinct from the L2 economics/fundamentals and the on-chain per-chain APIs in the catalogue. The projects endpoint lists every tracked L2 with its type (Optimistic Rollup, ZK Rollup, Validium, layer3…), category, host chain, maturity Stage, TVS and 7-day change. The project endpoint returns one rollup in full — the TVS breakdown (native / canonical / external, and ether / stablecoin / btc / other), the Stage, providers, purposes and the complete risk assessment. The risks endpoint returns just the risk rosette for a rollup with a sentiment tally. The summary endpoint aggregates the whole ecosystem — total TVS, project count and the distribution by Stage and by type. More than a hundred rollups tracked, updated live. Project lookup is by slug (arbitrum, base, optimism, zksync-era, scroll, linea, starknet).

Independent Reserve Exchange API

Live order-book exchange data from Independent Reserve, the regulated Australian / New Zealand crypto venue, over its public API — no key, nothing stored. This is the regional venue view for the AUD, USD, NZD and SGD order books: Australasian and Singapore on-exchange price discovery, distinct from the global-aggregate and the other regional-exchange APIs in the catalogue. The ticker endpoint returns a pair market summary — last traded price, 24h high/low, day volume, the live best bid and offer and the implied spread. The orderbook endpoint returns the live limit-order book — top bids and asks with cumulative depth and the bid/ask spread — so you can read on-venue liquidity. The trades endpoint returns the most recent executed trades. The history endpoint returns the hourly trade-history summary for the last N hours (per-hour open/high/low/close, volume and trade count). The markets endpoint lists every supported coin and the four fiat quote currencies. Forty-one cryptos (BTC, ETH, SOL, XRP and more) quoted against AUD, USD, NZD and SGD, updated live. Currency codes are case-insensitive and BTC is accepted either as btc or its upstream code xbt.
