Quickstart

Get a key, make a call, then pick what to build on.

1. Get an API key

Enter your email on Get started. A new address gets its key at once, with free monthly credits.

2. Make your first call

List every HyperCore market with its 24 h stats. Send the key as a Bearer token.

curl -s "https://api.femtos.xyz/v1/markets?layer=hypercore" \
  -H "Authorization: Bearer YOUR_API_KEY"

3. Pick what to build on

• API reference: every call and channel, with a live example.
• WebSocket streams: data pushed as it happens.
• MCP for agents: let an agent query the data.
