Give my AI agents real authority

Agents that hold scoped cryptographic authority over MCP — not a broad API key in an env var.

Three steps to your first call

The quickstart walks through each one with copy-pasteable requests.

  1. 01

    Get a key

    Create an account on pteri.org and generate an API access key.

  2. 02

    Make one call

    Hit a read-only endpoint to confirm your key and connectivity work.

  3. 03

    Create a wallet

    Create a wallet and its first address — that wallet is the identity anchor.
