Всё для интеграции цен в реальном времени и исторических данных: интерактивный справочник, SDK для Python и JavaScript, спецификация OpenAPI и коллекция Postman.

Быстрый старт

Python

# one file, standard library only (Python 3.9+)
curl -O https://app.marketapi.app/sdk/marketapi.py
pip install websockets          # only if you use the live stream

from marketapi import MarketAPI
api = MarketAPI("YOUR_API_KEY")
print(api.latest(["EURUSD", "XAUUSD"]))

JavaScript

// one ES module, no dependencies (Node 18+ and browsers)
curl -O https://app.marketapi.app/sdk/marketapi.mjs
npm install ws                  # only for the live stream in Node.js

import { MarketAPI } from "./marketapi.mjs";
const api = new MarketAPI({ apiKey: process.env.API_KEY });
console.log(await api.latest(["EURUSD"]));

Клиенты — это одиночные файлы, которые вы храните в своём проекте, поэтому ничего не нужно устанавливать из реестра пакетов и не нужно доверять стороннему коду. Положите файл рядом со скриптом или в любую папку из пути импорта.

marketapi.py marketapi.mjs Спецификация OpenAPI 3.1 · Коллекция Postman · Руководства · Журнал изменений · Оракул (смарт-контракты)

Создаёте смарт-контракт?

On-chain оракул цен передаёт вашему контракту те же цены в виде подписанных отчётов, которые он может проверить on-chain: GET https://api.marketapi.app/v1/oracle/report?symbols=XAUUSD&chain_id=10, затем submit(report, signature) и getPriceNoOlderThan(feedId, maxAge). Примеры на Solidity и ethers v6, адреса контрактов и ID фидов — в документации оракула.

HTTP код Значение Что делать

400 invalid_parameter A parameter is missing or malformed. Check the parameter named in detail.

400 too_many_symbols Too many symbols in one request. Split the request (up to 100 symbols).

400 range_too_large The time range is too long for this endpoint. Request shorter ranges and page.

400 credentials_in_query The API key was sent in the URL. Send it in the Authorization header.

401 unauthenticated No or an invalid API key. Send Authorization: Bearer <key>.

401 key_revoked The API key was revoked. Create a new key in the dashboard.

401 key_expired The API key has expired. Create a new key or extend it.

402 insufficient_balance No credits left. Top up or choose a plan.

402 plan_credits_used_up The plan's credits for this month are used up (your balance is never used while a plan runs). Add credits to the month or upgrade on the billing page.

402 plan_ended The API plan has ended; the balance is not used until you choose. Renew, pick a plan, or choose pay as you go on the billing page.

403 insufficient_scope The key lacks the scope this endpoint needs. Create a key with that scope.

403 ip_not_allowed The request came from an IP the key does not allow. Update the key's IP list.

403 account_inactive The account is suspended or not verified. Verify your email or contact support.

403 sandbox_not_billable Test keys cannot call billable endpoints. Use a live key.

404 not_found Resource not available. Check the URL; some features may be switched off.

404 unknown_symbol The symbol does not exist. Search /symbols or the ticker list.

404 free_tier_disabled The free tier is switched off. Use an API key.

405 method_not_allowed Wrong HTTP method. Use GET.

409 idempotency_mismatch Same Idempotency-Key reused with different parameters. Use a new key.

409 idempotency_key_used The Idempotency-Key was used and its answer is no longer kept (24 h, 2 MB). Send a new key for current data.

429 rate_limited Too many requests per minute or hour. Wait for Retry-After; batch symbols.

429 too_many_concurrent_requests Too many requests in parallel. Limit concurrency.

429 daily_limit Free-tier daily limit reached. Retry tomorrow or use an API key.

503 oracle_unavailable The oracle signing service is temporarily unavailable. Retry with back-off.

503 free_tier_unavailable The free tier is temporarily unavailable. Retry later.

503 free_tier_busy The free tier is busy. Retry later or use an API key.
