Développeurs

Tout pour intégrer des prix en temps réel et historiques : une référence interactive, des SDK Python et JavaScript, la spécification OpenAPI et une collection Postman.

Démarrage rapide

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"]));

Les clients sont des fichiers uniques que vous gardez dans votre projet : rien à installer depuis un registre de paquets et aucun code tiers à qui faire confiance. Placez le fichier à côté de votre script, ou dans n’importe quel dossier de votre chemin d’import.

Vous développez un smart contract ?

L’oracle de prix on-chain fournit à votre contrat les mêmes prix sous forme de rapports signés qu’il peut vérifier on-chain : GET https://api.marketapi.app/v1/oracle/report?symbols=XAUUSD&chain_id=10, puis submit(report, signature) et getPriceNoOlderThan(feedId, maxAge). Exemples Solidity et ethers v6, adresses des contrats et ID de flux dans la documentation de l’oracle.
