The indicators endpoint returns the whole dashboard in one call: the Selic policy target rate set by the Copom, the CDI interbank rate, IPCA monthly and 12-month inflation, and the official USD/BRL and EUR/BRL PTAX exchange rates — in mid-2026 Selic sat at 14.50%, 12-month IPCA near 4.4% and the dollar around 5.17 reais.

Live crypto token prices by contract address — no key, nothing cached. Unlike price APIs keyed on a coin slug, this prices a token by its on-chain contract address on its chain, exactly what you have when a token comes out of a wallet, a DEX pair or a transaction. The price endpoint returns the current USD price, symbol, decimals, a confidence score and the timestamp for one or many tokens at once, addressed as chain:address (ethereum:0xA0b8…, a Solana mint, etc.) or as coingecko:slug — USD Coin resolves to about $1.00 and Wrapped Ether to its live price, in one batched call. The historical endpoint returns a token's price at any past moment by Unix timestamp. The chart endpoint returns a price series over a span and period, so you can plot or back-test. It spans every chain DefiLlama indexes — Ethereum, Solana, BSC, Base, Arbitrum and dozens more — including long-tail tokens a slug-based API will not have.

The rates endpoint returns the Bank's policy interest rate — the overnight target that sets the price of money in Canada — plus CORRA, the Canadian Overnight Repo Rate Average benchmark, with recent history so you can see the last moves.

Live blockchain transaction, receipt and block lookup, read straight from the chain's public JSON-RPC node — no key, nothing cached.

The receipt endpoint returns just the execution result (status, gas used, logs, contract address). The block endpoint takes a block number or "latest" and returns its timestamp, transaction count, gas used and limit with utilisation, base fee and miner.

The reverse endpoint does the opposite — give it any Ethereum address and it returns that address's primary ENS name and the same profile, so a bare 0x… becomes a human identity.

For each category it gives the total market capitalisation, the 24-hour market-cap change, the 24-hour trading volume and the three largest coins in that sector — so you can see, for example, that the Meme sector is roughly a $30B market led by Dogecoin and Shiba Inu, and which narratives are pumping or bleeding today. The categories endpoint ranks every sector and can be sorted by market cap, 24-hour change or volume; the category endpoint returns one sector by id or name with its market-cap rank and description; the movers endpoint surfaces the top gaining and losing narratives over the last 24 hours, filtered to real sectors so micro-cap dust does not distort the board.

Live ERC-20 token metadata, read straight off the blockchain. Give it any token contract address and it returns the token's name, symbol, decimals and total supply — both as the raw on-chain integer and as a human-formatted number — by calling the ERC-20 contract directly via the chain's public JSON-RPC node (eth_call), confirming first that the address is really a contract.
