## Which one, for what

### APITemplate.io (F)

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:
- Maintenance & community, 11 against 5
- Transparency & trust, 60 against 49

Watch for: One API key per account or team with no scopes or read-only mode

### Robolly (D)

Good for: Template-driven images, PDFs and short videos for marketers and developers who want a hosted editor and simple synchronous calls.

Ahead on:
- Schema & documentation, 57 against 5
- Agent ergonomics, 75 against 24
- Payments & pricing, 35 against 30

Watch for: No OpenAPI or other machine-readable contract found


## Why the edge

### Schema & documentation: Robolly +52

- APITemplate.io (5): APITemplate.io's terms bar robots and other automatic devices on any portion of the Site or Service, so its sites were not re-read on 5 November, and the OpenAPI file's storage host answers robots.txt with an access-denied error, so readings of that file are struck. The REST guide links an OpenAPI 3.0.0 description for Postman or code generators, but every reading of the file is struck and none can be taken today (0). No llms.txt (404) and no Markdown docs for agents (0). The operation and parameter descriptions, types, enums, request samples and error schema were read from the file (0, 0 and 0). A `/v2` path in the guides, with no changelog (5). 0+0+0+0+0+5 = 5.
- Robolly (57): No OpenAPI or other machine-readable contract found for the REST API, and the MCP server is closed. The MCP page lists all nine tools and `get_template_modifications` returns each template's keys, constraints and examples at run time (8 of 25, on that partial evidence). llms.txt indexes the docs (10). The MCP page says what each tool does, which tools change templates or spend credits, and that there is no delete tool (14 of 20). Modification keys follow `{element-name}.{modification-key}` with constraints from the template rather than a fixed schema (7 of 15). Request examples throughout and an error code table with eight codes (13 of 15). /v1 paths with no changelog (5 of 15). 8 + 10 + 14 + 7 + 13 + 5 = 57.

### Agent ergonomics: Robolly +51

- APITemplate.io (24): APITemplate.io's terms bar robots and other automatic devices on any portion of the Site or Service, so its sites were not re-read on 5 November, and the OpenAPI file's storage host answers robots.txt with an access-denied error, so readings of that file are struck. Per the 9 October check except where struck. `export_type=file` returns bytes rather than a stored file and `expiration` sets how long a download URL lasts, per the secure PDF FAQ (15 of 25, an earlier partial kept). Pagination and filters, the error object and the `meta` reference were read from the struck file (0, 0 and 0). Calls are synchronous by default, and the five SDK repositories are generated clients from September 2023 with placeholder install commands, confirmed from clones on 5 November (9 of 15, an earlier partial kept). 15+0+0+0+9 = 24.
- Robolly (75): Nine MCP tools (25). The renders list pages with a cursor, and templates are found by name (14 of 20). Errors carry `errorCode` and `developerMessage` with eight documented codes (17 of 20). Identical renders are cached for 45 days, so repeats are free and safe, the MCP server has no delete tool, and annotations couldn't be read on the closed server (12 of 20). Renders return the file synchronously by default, but there's no SDK (7 of 15). 25 + 14 + 17 + 12 + 7 = 75.

### Transparency & trust: APITemplate.io +11

- APITemplate.io (60): APITemplate.io's terms bar robots and other automatic devices on any portion of the Site or Service, so its sites were not re-read on 5 November, and the OpenAPI file's storage host answers robots.txt with an access-denied error, so readings of that file are struck. Per the 9 October check. Closed service under terms of use dated 8 April 2022, which can change without prior notice. The SDK repositories have no licence file (13). Privacy policy dated 21 January 2024 and a public DPA with standard contractual clauses. Request logs are kept two weeks, account data is deleted within 30 days of cancellation, and free accounts' files are purged after one year. Retention of personal data is otherwise stated only as long as reasonably needed (22). Clause 15.8 of the terms promises 60 days' written notice before a service is withdrawn, while clause 2.24 reserves the right to modify or discontinue any part with or without notice. No dated deprecation notices found (6, an earlier partial kept). Eleven sub-processors named with purpose and country, 14 days' notice of new ones in the DPA, and four storage regions listed (17). 13+22+6+17 = 58.
- Robolly (49): Closed service under terms effective 8 April 2026 from Avantis Innovations LLC in Wyoming. The terms can change without notice (15). The privacy policy of the same date covers Google sign-in and Sheets data, says spreadsheet rows aren't kept beyond a render and account data is deleted with the account, and otherwise names no periods (10 of 30). No deprecation policy or notices (0). Hosting is described only as third-party vendors, with no processors or locations named, while the footer says Made in EU (2 of 20). 15 + 10 + 0 + 2 = 27.

### Maintenance & community: APITemplate.io +6

- APITemplate.io (11): APITemplate.io's terms bar robots and other automatic devices on any portion of the Site or Service, so its sites were not re-read on 5 November, and the OpenAPI file's storage host answers robots.txt with an access-denied error, so readings of that file are struck. Per the 9 October check. No changelog or release notes exist, and the file's Last-Modified header was metadata, not a dated release (0). No dated changelog entries in the last 90 days (0). Support by email with a stated reply within 24 hours and response times in the SLA, with no public changelog (6). Five SDK repositories, each a generated client committed on 17 September 2023; the Python and JavaScript clones on 5 November show no later commit (3). No tags, CI results or licence files in those repositories (2). 0+0+6+3+2 = 11.
- Robolly (5): No changelog, release notes or dated API change was found. The sitemap marks every docs page as modified on 4 November 2026, which reads as a site rebuild rather than a change, so it isn't counted (0). No dated changes since 8 August (0). Support by email, with chat on higher plans; not tested (5 of 15). Not in the official MCP registry and no SDKs (0). No public package or repository (0). 0 + 0 + 5 + 0 + 0 = 5.

### Payments & pricing: Robolly +5

- APITemplate.io (30): APITemplate.io's terms bar robots and other automatic devices on any portion of the Site or Service, so its sites were not re-read on 5 November, and the OpenAPI file's storage host answers robots.txt with an access-denied error, so readings of that file are struck. Per the 9 October check. No x402, MPP or L402 (0). Plan prices with monthly file counts are public without a login, and no per-file or overage rate is published (10). Free plan of 50 files a month with no card (20). A person signs up in a browser to get the key (0). 0+10+20+0 = 30.
- Robolly (35): No x402, MPP or L402 (0). Plan prices are public and a table gives the credit cost of each format and size (15 of 20). 7-day trial with no card (20). A person signs up, then copies the key or approves OAuth (0). 0 + 15 + 20 + 0 = 35.

## Verdicts

**APITemplate.io.** APITemplate.io publishes rate limits, regional endpoints, a 99.9 per cent uptime SLA and a free plan of 50 files a month with no card. 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.

**Robolly.** Robolly's nine MCP tools, synchronous renders, typed error codes and free cached re-renders keep template rendering cheap and predictable for an agent, and OAuth connections can be revoked per client. There is no OpenAPI file, changelog or dated release, and API access starts at $39 a month after a 7-day trial.

## 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. Set `expiration` in minutes or `export_type=file` for sensitive output. By default the download URL does not expire
3. On HTTP 429 pause and retry on your own schedule. The docs give no `Retry-After` header or backoff interval
4. Use Direct URL `auth` codes only in page markup, with a quota and an expiry set, never the API key

### Robolly

1. Call `get_template_modifications` before `render` to learn the keys a template accepts
2. Send renders one at a time; the API refuses more than 3 a second with `rate-limit`
3. Repeat an identical render freely; it is cached for 45 days and costs nothing
4. Poll `get_render` after `render_video`, since video renders are queued
5. Stop on `render-limit-exhausted` and tell the user the monthly credits are spent
