## Which one, for what

### Photoroom API (C)

Good for: Product-photo work at volume, such as cutouts, white backgrounds, shadows, generated scenes and clothing shots, one image a call.

Ahead on:
- Schema & documentation, 86 against 77
- Agent ergonomics, 64 against 49
- Security & auth, 54 against 30
- Payments & pricing, 40 against 20
- Transparency & trust, 68 against 48

Watch for: No status page was found on the site or in the docs, so there is no public incident history to read

### PostNitro (E)

Good for: An agent that must produce a designed, on-brand carousel or slide video and book it on LinkedIn, Instagram, TikTok, Threads, Facebook Pages or Pinterest in one chain.

Ahead on:
- Maintenance & community, 65 against 23

Watch for: No status page, incident history, SLA, security.txt or certification was found

## Verdicts

**Photoroom API.** A call costs $0.02 for background removal or $0.10 for any combination of edits, and a sandbox key gives 1,000 free watermarked calls a month without a card. No status page or official SDK was found, and Photoroom's privacy policy and security page disagree on whether API images train its models.

**PostNitro.** A hosted MCP server and REST API let an agent turn a topic, article or own slides into a branded carousel, image or slide video and schedule it, with OAuth, numbered rate limits and Markdown docs. No status page, security contact or idempotency key was found, and the privacy policy contradicts the vendor's no-training statement.

## Before you call either

### Photoroom API

1. Send the key in the `x-api-key` header. Prefix it with `sandbox_` while testing, because calls with the plain key consume paid images
2. Save the response body as a file. A 200 returns image bytes, PNG by default, and any other status returns JSON with `error.message` or `detail`
3. Send model selectors such as `pr-ai-shadows-model-version: 2026-04-15` as HTTP headers, not form fields. They are not in the OpenAPI file
4. Stay under 60 images a minute. On 429 back off with an exponential delay, and set a client timeout of at least 60 seconds for AI edits
5. Use `POST /v2/edit` with `imageFile` for local files and `GET /v2/edit` with `imageUrl` for hosted ones. Each call takes one image

### PostNitro

1. Call `postnitro_set_defaults` once with a template, brand and AI preset, or every generate call must carry those IDs
2. Pass the `designId` from `postnitro_get_output` to scheduling, never the `embedPostId`, or the call fails with `Design not found`
3. For a LinkedIn PDF post, set `linkedinPostSettings.postType` to `document` with a 5 to 90 character `postTitle`
4. Ask for the `DESIGN` output or save as `DRAFT` when a person must approve before anything publishes
5. Keep to 5 create calls a minute per key and wait for `Retry-After` on a 429
