API keys
WAVE authenticates with a Bearer key. Create a developer account to issue one — no credit card to start.
Pass the key via the SDK constructor option, the WAVE_API_KEY environment variable, or an Authorization: Bearer header on raw HTTP calls.
The key is shown ONCE at issue time. Copy it immediately and store it in a secret manager — WAVE never stores the plaintext and cannot show it again.
Autonomous agents can skip keys entirely on metered endpoints: pay per call over HTTP-402 (x402 / MPP) by signing a payment intent instead.
