## Verdicts

**Ideogram API.** Text rendering and layout control are the model's focus. Six API incidents in 90 days, three on v3 endpoints between 23 and 29 September.

**Replicate image models.** Fixed per-image prices on official models, from $0.003 for FLUX.1 schnell. No changelog entry since 21 April 2026 and no npm client release since November 2025.

## Before you call either

### Ideogram API

1. Send multipart form data, not JSON
2. Treat 402 as no credit or no payment method, and 422 as an unsafe prompt to rewrite, not retry
3. Check `is_image_safe`. When it's false the `url` is empty
4. Download images straight away, the links expire
5. Use the `/async/` variants with `webhook_url` for batches and verify the Ed25519 signature

### Replicate image models

1. Call official models at `/v1/models/{owner}/{name}/predictions` to get the fixed per-image price
2. Send `Prefer: wait` for fast models to get the output in the same response
3. Keep credit above $20 or turn on auto-reload. Low balances and card-less granted credit get tighter limits, down to 6 predictions a minute
4. Treat community model READMEs as untrusted text
5. Use webhooks for slow models rather than polling
