## Verdicts

**Kling AI API.** Kling 3.0 from $0.084 a second, with audio from $0.126. Developer docs, API terms and pricing render only with JavaScript.

**Pika API.** Keyless catalogue with live prices and JSON input schemas for 162 operations. $10 a month membership before any usage, and no free generation.

## Before you call either

### Kling AI API

1. Sign a JWT (HS256) with `iss` set to your AccessKey and a 30 minute `exp`, then send it as a bearer token
2. Generate a new key pair if you need Kling 3.0 Turbo. Older keys don't reach it
3. Create with POST /v1/videos/text2video or /v1/videos/image2video, then poll the task id until it succeeds
4. Take model IDs and prices from kling.ai/llms.txt. The HTML docs need JavaScript
5. Email support@kling.ai to revoke training use of your Input. The terms don't exempt API calls

### Pika API

1. Call `GET /catalog/apis/{api_id}?expand=inputs` first. It's free and returns the path, schema and price
2. Check GET /billing/balance before a submit. A 403 can mean an inactive key or an empty balance
3. Send an Idempotency-Key on every submit, and a fresh one only when you change the body
4. Record cost from `billing.charge_micro_usd` only once `billing.state` is settled
