Leonardo Interactive Pty Ltd is a Canva subsidiary (15). leonardo.ai returns 403 to our fetcher, so we couldn't read the privacy policy or retention statements in this run (0). Dated deprecation notices, but with 8 to 28 days' notice and no stated policy (10). No subprocessor list or data locations found (0).\n- SurgePix API (28): The editorial half. A closed service whose terms name no company or address. They restrict any commercial use of what the service produces without SurgePix's permission, and contain clauses from an unrelated product (a \"big data\" query platform and \"non-resume content\"). The skills are MIT. Unclear terms, with a little credit for the open skills (5). The privacy policy is dated both 10 June 2026 and 1 July 2022, describes WeChat and phone registration and \"domestic servers\", and gives no retention periods. The API reference says uploads go to Tencent Cloud storage in Seoul as public URLs. No DPA. The statements don't agree (5). No deprecation policy or notices, and the terms let changes take effect on publication without notice (0). Tencent Cloud Object Storage in ap-seoul is named in the API reference, and Alipay and WeChat Pay in the privacy policy. No subprocessor list or stated data location (4). 5+5+0+4 = 14.\n\n### Payments \u0026 pricing: SurgePix API +20\n\n- Leonardo.Ai API (0): No x402, MPP or L402 (0). No per-image price list. Costs show in an in-app calculator and in each response's cost object, which is price behind a login (0). No API free tier documented (0). Browser sign-up (0).\n- SurgePix API (20): No x402, MPP or L402 (0). Plan prices and monthly credits are public, but credits are spent per token with no per-call price for any API task, so plan-only pricing (10). A free plan with 25 credits a day. The pages don't say whether a card is needed or whether a free account can create API keys, so half, a judgement call (10). A person signs up in a browser and creates the key in settings (0). 0+10+10+0 = 20.\n\n### Maintenance \u0026 community: SurgePix API +18\n\n- Leonardo.Ai API (48): The last dated API change is the removal of Sora 2 on 9 July 2026, 84 days ago. The TypeScript SDK's last release, 4.21.3, was on 21 April 2026 (20). For models we look at churn and notice. Six removals or breaking changes since April 2026 with 8 to 28 days' notice and no stated policy (3). Public deprecations page and a contact form (6). Official TypeScript and Python SDKs, the TypeScript one five months old (12). The SDK publishes from GitHub Actions through npm trusted publishing (7).\n- SurgePix API (66): The last dated change is GPT-Image-2.5 on 23 October 2026, 10 days before the check (30). Changelog entries on 15, 22 and 23 October, 16, 9 and 2 September 2026, more than three in 90 days (20). For a closed service, a dated changelog, a Discord server and a contact email. We didn't open Discord or the GitHub issues, so answering isn't confirmed (8). No official SDK. The skills are maintained client scripts with tags from v1.0.0 (4 June 2026) to v1.5.0 (2 September 2026), a judgement call (5). The repository's CI checks SKILL.md front matter only, with no tests, and the skills aren't published as a package (3). 30+20+8+5+3 = 66.\n\n### Reliability: Leonardo.Ai API +15\n\n- Leonardo.Ai API (30): No status page. status.leonardo.ai failed TLS when the listing was researched and the limits guide links none (0). No readable incident history (5). Concurrency, queue and rate limits are defined and default numbers sit in the limits reference, 10 concurrent jobs per the listing's research (15). The limits guide says nothing about which status code comes back when a limit is hit or how to back off (0). No SLA found (0). The v2 generations endpoint is GA (10).\n- SurgePix API (15): Read with the hosted lines. No status page was found on surgepix.ai or in the docs, and status.surgepix.ai doesn't resolve (0). With no history to read, the incident line takes the floor (5). No rate limits with numbers are documented. The terms say \"non-human continuous or frequent query operations\" lead to automatic account suspension, with no threshold given (0). No 429 or backoff guidance. The skill scripts poll every 2 seconds for up to 5 to 15 minutes, but that is client code, not a documented policy (0). No SLA, and the terms disclaim uninterrupted service (0). The API isn't labelled beta or preview, and API keys have been self-serve since 2 June 2026 per the changelog (10). 0+5+0+0+0+10 = 15.\n\n### Schema \u0026 documentation: Leonardo.Ai API +5\n\n- Leonardo.Ai API (45): No public OpenAPI spec found (0). llms.txt for the docs (10). Guides describe each model, but we found no when-not-to-use guidance (8). The SDKs are typed with Zod schemas, and one `model` string on the v2 endpoint chooses among many shapes (10). Examples in the guides, no error catalogue found (7). v1 and v2 paths and a dated deprecations page, no full changelog (10).\n- SurgePix API (40): No OpenAPI or other machine-readable contract was found (0). surgepix.ai/llms.txt returns 404. The docs are HTML pages, but the 15 SKILL.md files in the MIT repository are Markdown written for agents, so half (5). The API reference states the purpose of each of its five operations and the async and session model. The SKILL.md files add trigger phrases and explicit do-not-use routing between skills, but 11 of the task endpoints the skills call appear only in their scripts, with no reference (10). Parameter tables give type and required for the documented operations, with no enums or limits, and the undocumented endpoints have no schema at all (7). JSON examples for every documented operation and an error table with 401, 404 and `error.file.sensitive_content` (10). A dated public changelog from 11 March 2026, but no version in the API path and no API-specific change notes (8). 0+5+10+7+10+8 = 40.\n\n## Score by category\n\n| Category | Weight | Leonardo.Ai API | SurgePix API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 30 | 15 | Leonardo.Ai API +15 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 45 | 40 | Leonardo.Ai API +5 |\n| Agent ergonomics | 13% (16.2 this run) | 54 | 53 | Leonardo.Ai API +1 |\n| Security \u0026 auth | 14% (17.5 this run) | 40 | 41 | SurgePix API +1 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 0 | 20 | SurgePix API +20 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 48 | 66 | SurgePix API +18 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 50 | 28 | Leonardo.Ai API +22 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **37.7 · F** | **36 · F** | |\n\n## Facts side by side\n\n| Fact | Leonardo.Ai API | SurgePix API |\n| --- | --- | --- |\n| Kind | Model API | HTTP API |\n| Vendor | Leonardo.Ai (Canva) | SurgePix |\n| Hosted endpoint | `https://cloud.leonardo.ai/api/rest/v2` | `https://api.surgepix.ai/api` |\n| Transports | HTTP, Streamable HTTP | HTTP |\n| Auth | API key | API key |\n| Pricing | Pay per use | Freemium |\n| x402 | no | no |\n| Licence | none | Proprietary hosted service under the Surgepix User Agreement, which names no company and restricts commercial use without SurgePix's permission.

No per-image price list outside the logged-in calculator.\n\n**SurgePix API.** A small, readable API with async tasks and MIT skill scripts that cover posters, decks, edits and translation. Only background removal is documented, the terms name no company and restrict commercial use and automated querying, and uploaded files become public URLs.\n\n## Before you call either\n\n### Leonardo.Ai API\n\n1. Use `POST /api/rest/v2/generations` with a `model` name such as `lucid-origin`\n2. Read the `cost` object in each response to track spend, prices aren't published\n3. Send `quality`, not `mode`. `mode` was retired on 2026-05-04\n4. Set a webhook callback URL on the key instead of polling long jobs\n5. Check the deprecations page before relying on a third-party model, removals follow the provider\n\n### SurgePix API\n\n1. Send the key as the raw `authorization` header value, with no `Bearer` prefix\n2. Don't upload confidential files. The upload flow returns a public URL for every file\n3. Check `code` in the JSON body as well as the HTTP status, since failures come back as a non-zero `code` with a `msg`\n4. Poll `GET /tasks/{taskId}` within 24 hours, after which the task returns 404\n5. Get written permission before using outputs commercially, since the terms restrict commercial use\n\n## Questions\n\n### Which is better for AI agents, Leonardo.Ai API or SurgePix API?\n\nLeonardo.Ai API scores 37.7 (F) on agent readiness against SurgePix API's 36 (F), and leads in 4 of 7 scored categories. SurgePix API leads on payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Leonardo.Ai API and SurgePix API need an API key?\n\nBoth need an API key.\n\n### Can an agent call Leonardo.Ai API and SurgePix API without installing anything?\n\nYes. Leonardo.Ai API has a hosted endpoint at https://cloud.leonardo.ai/api/rest/v2 and SurgePix API at https://api.surgepix.ai/api.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/leonardo-ai-vs-surgepix.json, and with the fewest tokens: https://www.anchorterminal.com/compare/leonardo-ai-vs-surgepix.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"leonardo-ai\", \"b\": \"surgepix\"}`.
