System Documentation

What problem does it solve?

This Skill enables Internet Computer (IC) canisters to securely and reliably make HTTPS requests to external web services, bridging on-chain logic with off-chain data and functionality.

Core Features & Use Cases

  • External API Integration: Fetch data from any public web API (e.g., market data, weather services).
  • Secure Communication: Utilizes HTTPS for secure data transfer.
  • Consensus-Ready: Employs transform functions to ensure deterministic responses across all replicas for consensus.
  • Cycle Management: Automatically handles cycle costs for outgoing requests.
  • Use Case: A decentralized application needs to display real-time cryptocurrency prices. This Skill allows the canister to query an external price API like CoinGecko and display the data on-chain.

Quick Start

Use the https-outcalls skill to fetch the current ICP price in USD from an external API.
