Endpoints (63 live)

• GET /api/crypto/token-price-historical — USD price of up to 20 tokens at a specific Unix timestamp (seconds). Same coverage as the live price endpoint, for point-in-time valuation: cost basis, tax lots, historical portfolio snapshots, or auditing what a treasury was worth on a given day. (0.01 USDC on Base)
• GET /api/crypto/trending — What the market is searching for right now: the trending coin list plus trending search terms and non-fungible collections, exactly as the upstream search index reports it. Useful for content agents, news summarisation or meme-coin screening. (0.01 USDC on Base)
• GET /api/defi/tvl-history — Daily total value locked series, either aggregated across every chain or for the chain passed in the query. The macro backdrop for any DeFi narrative or risk dashboard. (0.01 USDC on Base)
• GET /api/chain/nonce — Transactions sent by an address, which is the next nonce to use for the pending or latest block. Used by any agent that signs its own transactions and needs the counter without running a node. (0.01 USDC on Base)
• GET /api/execution/check — One verdict on a concrete order before it is sent: effective price, slippage in bps and in USD, how much of the visible book the order eats, and the largest size that still fits your slippage budget. Walks the live order book level by level (you never download the book) and answers ok / ajustado / riesgo with the reasons. Use it to size an order, to compare venues, or before quoting a fill. (0.1 USDC on Base)
• GET /api/chain/info — Chain id, client version and current block height for Base, Ethereum, Arbitrum, Optimism or Polygon, in one call with no API key and no node to run. The cheapest liveness and identity probe for a chain before you build on it. (0.01 USDC on Base)
• GET /api/crypto/markets — Market table of the top coins by market capitalisation: price, market cap, volume, circulating supply, all-time high and 1h/24h/7d changes, up to 250 rows per call with pagination. Normalised into one flat row per coin; falls back to a second provider if the first one rate-limits. (0.01 USDC on Base)
• GET /api/fx/convert — Convert an amount from one currency to another using the ECB reference rate of the day, and return the rate, the converted amount, the date of the rate and a rounding hint. For invoices, expense reports and reports that must cite an official rate. (0.01 USDC on Base)
• GET /api/crypto/orderbook — Best bid and ask, absolute and relative spread, mid price, and the depth available within a configurable percentage of the mid, for a spot pair. Answers 'can I trade this size without moving the price' in one call, without pulling a full order book. (0.02 USDC on Base)
• GET /api/fx/rates — Official daily reference rates published by the European Central Bank, for the currencies traded against the euro. Not a market feed, the reference rate: what accounting, invoicing and reporting workflows are supposed to use. Keyless and cached. (0.01 USDC on Base)
• GET /api/crypto/klines — Exchange OHLCV candles for a spot pair: open, high, low, close, volume, quote volume and trade count, up to 200 candles per call at any interval from one minute to one month. Returns one flat object per candle and falls back to a second exchange if the first one rate-limits or blocks. (0.01 USDC on Base)
• GET /api/crypto/token-price — Spot price in USD for up to 20 tokens identified by contract address, on Base, Ethereum, Arbitrum, Optimism or Polygon, with decimals and confidence. No API key, no rate limit surprises: useful to value a wallet, a treasury or an invoice in tokens that an exchange price endpoint cannot resolve. (0.01 USDC on Base)
• GET /api/chain/logs — Event logs emitted by a contract between two block heights, with topics, data, block and transaction reference. This is how you read ERC-20 transfers, swaps or any custom event without an indexing service. The block range is capped so public nodes answer. (0.01 USDC on Base)
• GET /api/crypto/tickers — 24h statistics for up to 10 symbols: last price, price change and percent, weighted average, high, low, base volume and quote volume. Flattened from the exchange payload so the numbers are ready to compare or store. (0.01 USDC on Base)
• GET /api/chain/receipt — Just the receipt: status, gas used and cumulative gas, effective gas price, block, index and logs. Cheaper than the full transaction view when all the caller needs is 'did it land and what did it cost'. (0.01 USDC on Base)
• GET /api/crypto/ohlc — Open/high/low/close candles for one coin (timestamp, open, high, low, close) over 1 to 365 days. The candle granularity is chosen by the upstream provider for the requested window. Drop-in input for a trading or charting pipeline without a CoinGecko key. (0.01 USDC on Base)
• GET /api/chain/transaction — One call returns both the transaction and its receipt: status, from, to, value in native units and wei, gas price and gas used, effective fee in native units, block, nonce and the number of logs emitted. Saves the two round trips a payment verifier always needs. (0.02 USDC on Base)
• GET /api/crypto/history — Time series of price, market cap and total volume for one coin over 1 to 365 days, at the resolution CoinGecko serves (hourly up to 90 days, daily beyond). For charting, backtesting a strategy or computing volatility. (0.01 USDC on Base)
• GET /api/chain/token-info — Name, symbol, decimals and total supply of an ERC-20 contract, read straight from the chain. Use it to label an unknown token, validate a contract before paying it, or compute supply-based metrics without trusting a token list. (0.02 USDC on Base)
• GET /api/defi/stablecoins — Every tracked stablecoin with circulating supply, supply yesterday and a week ago, chain breakdown, peg type and mechanism. The supply table behind most stablecoin dashboards. Raw upstream payload, cached at the edge. (0.01 USDC on Base)
