Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Reliability Placid API + MCP +60

Pixelixe 15

Hosted lines. No status page found on the site or in the docs (0). No readable incident history (5). No rate limit is published; the terms only forbid circumventing them (0). No 429, Retry-After or backoff guidance. Every error, a wrong key and exhausted credits included, is a 400 with a message (0). No SLA found; the terms supply the service as is (0). API v2 is current and not labelled beta (10). 0 + 5 + 0 + 0 + 0 + 10 = 15.

Placid API + MCP 75

Hyperping status page at status.placid.app with separate App and API components and 90-day bars (20). No incidents are posted. The page's own figure for the API is 99.963 per cent over 90 days, roughly 48 minutes of recorded downtime with no write-up, so minor rather than clean (20). 60 requests a minute and 10 simultaneous create_now requests, documented (15). X-RateLimit-Limit, -Remaining and -Reset headers and exponential backoff advice on 429, but no idempotency key or safe-retry note for renders, which are writes (10). No SLA found on the pricing page or in the docs (0). REST API 2.0 is GA (10).

Schema & documentation Pixelixe +32

Pixelixe 66

OpenAPI 3.1 (version 2.0.0) at pixelixe.com/pixelixe-openapi.json, but it covers four endpoints, authentication, document search, graphic automation and photo effects, and leaves out the JSON-to-graphic and image processing APIs (18 of 25). llms.txt exists but routes readers to marketing pages; the MCP reference is written for LLMs (7 of 10). The MCP reference says what each of the seven tools maps to, that pixelixe_generate_graphic_variant 'is not a free-form layout API', lists common mistakes and how to present outputs (17 of 20). The MCP layer documents canonical field names and refuses legacy aliases; the REST modifications are open structures keyed by element name (10 of 15). Request examples throughout, but errors are one table of message strings all returning 400 (8 of 15). /v2 paths and a deprecated V1, with no changelog (6 of 15). 18 + 7 + 17 + 10 + 8 + 6 = 66.

Placid API + MCP 34

No OpenAPI or other machine-readable contract, and the MCP tool definitions aren't published (0). /llms.txt returns 404 (0). Endpoint pages state purpose and warn that create_now may fail under high load (12). template_uuid is the one required field and status is an enum, but layers and modifications are open objects keyed by layer name (8). Request and response examples per endpoint, and an error page with six codes but no body format (9). Docs are versioned 2.0, but the changelog on Headway carries no dates and its newest entries predate the MCP server (5).

Transparency & trust Placid API + MCP +17

Pixelixe 41

Closed service under terms of 19 March 2026 that choose French law but name no company (12 of 30). The privacy policy of 7 April 2026 keeps account data while the account is active and 'as long as reasonably necessary' after, with no periods, and says nothing about AI processing or training (10 of 30). V1 is marked deprecated in the docs with no dates or notice period (5 of 20). Processors are described only by category, with Google Analytics named, and data processed in France, the EEA and other vendor countries (5 of 20). 12 + 10 + 5 + 5 = 32.

Placid API + MCP 58

Closed service under published terms, per the 30 September check (15). Privacy policy updated 18 November 2024, a DPA on request, and raw request data kept 'for a limited amount of time' with no period stated (12). No deprecation policy or dated notices. The old changelog says v1 remains functional (3). Subprocessor categories only, with 'We don't publish further details of our data processors', and no hosting location (3).

Maintenance & community Pixelixe +12

Pixelixe 19

No dated release or API change was found. The newest dated items are the MCP registry entry of 26 March 2026 and the privacy policy of 7 April 2026, more than 180 days before this check (0). No three dated changes since 8 August (0). No changelog. Support by email at inquiries@pixelixe.com, not tested (4 of 15). com.pixelixe/pixelixe-mcp is in the official MCP registry under a domain-verified namespace; there are no official SDKs (15). No public package or repository (0). 0 + 0 + 4 + 15 + 0 = 19.

Placid API + MCP 7

We found no dated release or API change. The Headway changelog has no dates, its entries mention Integromat and a v2.0 launch, and /changelog on placid.app returns 404 (0). No dated entries in the last 90 days (0). Support by email named in the error docs, public changelog stale (4). Official PHP and Laravel libraries were last tagged v1.0.1 on 2022-07-20 and still call placid.app/api/rest (3). No CI on either library (0).

Agent ergonomics Pixelixe +9

Pixelixe 49

Seven compact MCP tools (25). Document and design-set search filters, with no pagination documented (10 of 20). All errors are 400 with free-text messages, so an agent can't branch on a code (6 of 20). No idempotency keys, and annotations couldn't be read on the closed server. The MCP tools only read and create, with nothing that deletes (5 of 20). Few required fields, but no official SDK (3 of 15). 25 + 10 + 6 + 5 + 3 = 49.

Placid API + MCP 40

Image, PDF and video objects are small and the MCP can be limited to chosen templates and creative types (15). We found no pagination or filter parameters on the pages we read (5). Six status codes documented without an error body format (10). No idempotency key, no MCP tool annotations we could see, and DELETE removes an image for good. Polling the polling_url is safe (3). Only template_uuid is required, but the official libraries are PHP and Laravel only, both last tagged v1.0.1 on 2022-07-20 (7).

Payments & pricing Placid API + MCP +5

Pixelixe 30

No x402, MPP or L402 (0). Plan prices with monthly document counts are public, with no per-image price (10). 10-day trial with no card (20). A person signs up and copies the key, or approves OAuth in a browser (0). 0 + 10 + 20 + 0 = 30.

Placid API + MCP 35

No x402, MPP or L402 (0). Plan prices are public per the 30 September check (our fetch of the pricing page didn't render the amounts), and the FAQ states credit costs per unit, 1 per image, 2 per PDF page and 10 per 10 seconds of video (15). Free trial with no card and unlimited watermarked previews in test mode (20). A person signs up in a browser and copies a project token (0).

Verdicts

Pixelixe

Pixelixe's seven MCP tools and their LLM-oriented reference make template fills and JSON-to-graphic creation simple to call, with an OpenAPI file for the core endpoints. Every error comes back as a 400 with a message, there are no published rate limits, status page or changelog, and API access starts at $59 a month.

Placid API + MCP

Hyperping status page with separate App and API components and 90-day history. No OpenAPI, no llms.txt, and the MCP tool list isn't published.

Before you call either

Pixelixe

  1. Call pixelixe_search_documents first to find the document_uid of the template to reuse
  2. Use pixelixe_generate_graphic_variant to fill an existing template; it can't change the layout
  3. Read the error message text, since every failure is a 400
  4. Stop and tell the user on 'Not enough Credits'; retrying won't help
  5. For a batch, use pixelixe_create_multiple_images and summarise counts rather than inlining every image

Placid API + MCP

  1. Send the token in the Authorization header, not as ?api_token=, wherever the client allows it
  2. Read X-RateLimit-Remaining and wait for X-RateLimit-Reset after a 429
  3. Use test mode for watermarked previews while matching layer names, then switch to live renders
  4. Leave create_now off for batches, since it caps at 10 at once and may fail under load
  5. Poll the returned polling_url or pass webhook_success, since images start as queued
