## Which one, for what

### APITemplate.io (D)

Good for: Owners who need invoices, certificates, reports and social images filled from templates, with HTML, URL and Markdown to PDF on the same key and a choice of storage region.

Ahead on:
- Reliability, 65 against 42
- Security & auth, 53 against 30
- Payments & pricing, 30 against 20
- Transparency & trust, 59 against 48

Also in its favour:
- Free to start without a card

Watch for: One API key per account or team with no scopes or read-only mode, and `GET /v2/delete-object` deletes a file with a GET request

### 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:
- Schema & documentation, 77 against 52
- Maintenance & community, 65 against 11

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

## Verdicts

**APITemplate.io.** A public OpenAPI description covers 12 operations, with rate limits, four regional endpoints and a 99.9 per cent uptime SLA published. Each account or team has one unscoped API key, no changelog or deprecation notices were found, the SDK repositories date from September 2023, and two documentation pages name different regional hostnames.

**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

### APITemplate.io

1. Send the key in the `X-API-KEY` header and pick the regional host first, because requests and output are processed and stored in that region
2. Call `GET /v2/list-templates` with `with_layer_info=1` before `POST /v2/create-image`, so the `name` values in `overrides` match the template's elements
3. Set `meta` to your own reference on each generation and check `GET /v2/list-objects` before retrying, since there is no idempotency key
4. Set `expiration` in minutes (1 to 10080) or `export_type=file` for sensitive output. By default the download URL does not expire
5. For `async=1` you must pass `webhook_url`. The callback is a GET with the result in the query string, retried three times
6. On HTTP 429 pause and retry on your own schedule. The docs give no `Retry-After` header or backoff interval

### 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
