Why the edge:
- Maintenance & community, Eat This Much Partner API +48: Eat This Much Partner API 58 (Read as a closed service. Changelog entry 4.2.0 dated 15 October 2026 (30). Four dated entries in the 90 days to 3 November, 5 August, 6 August, 16 September and 15 October 2026 (20). A support address in the OpenAPI contact block and the changelog, no community channel (8 of 15). No official SDK; the docs point to Postman (0). No package to judge (0). Total 58.); Nutritionix API 10 (Read as a closed service. The newest dated first-hand change to the API's docs is the guide's update of 14 March 2024, more than 180 days before 3 November 2026; Syndigo's sub-processor list of 13 April 2026 and the vue-nutrition-label push of February 2026 are not API changes (0 of 30). No three dated changes in 90 days (0 of 20). Support through Syndigo's form and support@nutritionix.com for caching, no public changelog or community channel (5 of 15). No current official SDK; library-python last pushed December 2022, the label widget June 2024 (3 of 15). The organisation's packages show no CI or recent releases (2 of 10). 0 + 0 + 5 + 3 + 2 = 10.)
- Schema & documentation, Eat This Much Partner API +30: Eat This Much Partner API 75 (Public OpenAPI 3.0.3, version 4.2.0, at /g/openapi.yaml with 14 operations and named schemas (25). No llms.txt or Markdown docs; the docs page is the OpenAPI document and a Postman guide (0 of 10). Every operation states its purpose, its credit cost and its concurrency limit, and the week endpoint says when to use render separately; little on when not to use a call (14 of 20). Enums on preset_diet, output, format, generator_focus, num_foods and food_output, but the generate request schemas list no required properties, with the required inputs stated in prose (10 of 15). curl samples on six operations, error responses 400, 401, 404, 429 and 500 with an IssueMap of field messages (12 of 15). The version is in info only, paths carry no version, but the changelog dates each change and labels breaking ones (14 of 15). Total 75.); Nutritionix API 45 (No OpenAPI or similar document was found (0 of 25). Syndigo's docs portal serves an llms.txt index and a Markdown twin of every Nutritionix page (10). Each endpoint page states its purpose with usage guidance, such as debouncing instant searches and using the right follow-up endpoint for common and branded foods (13 of 20). Parameters are typed with defaults, but the only required column reads 'Required for Authentication', taxonomy_node_id is typed boolean while described as an id, and claims values sit in prose (8 of 15). Request and response examples on each endpoint; six error statuses with one line each and no body format (9 of 15). v2 in the path, no changelog, and the API guide last updated on 14 March 2024 (5 of 15). 0 + 10 + 13 + 8 + 9 + 5 = 45.)
- Agent ergonomics, Eat This Much Partner API +11: Eat This Much Partner API 62 (food_output simple or expanded, include_groceries on or off, and JSON, HTML or PDF output size responses (20 of 25). Food search has filters and pagination and usage history pages at 100; generation takes exclusions and per-meal settings (16 of 20). IssueMap errors name the field, 429 means a concurrency limit, 404 on food and key ids (14 of 20). No idempotency keys; generation is randomised and charged per call, so a retry costs again (4 of 20). Three required inputs with defaults for the rest, no official SDK (8 of 15). Total 62.); Nutritionix API 51 (Instant returns at most 20 common and 20 branded items and premium `detailed_nutrients` picks up to three nutrients, but natural nutrients returns every food with a full nutrient array and there is no general field selection (12 of 25). No pagination; filters by branded, common, brand id, brand type and region (10 of 20). Six statuses with a line each, no codes in the body, and limit errors folded into 401 (7 of 20). Every endpoint is a read and safe to repeat (14 of 20). One required parameter per endpoint and sensible defaults, but no official SDK on the developer page beyond a label widget, and the organisation's Python library was last pushed in 2022 (8 of 15). 12 + 10 + 7 + 14 + 8 = 51.)
- Reliability, Eat This Much Partner API +8: Eat This Much Partner API 23 (Read with the hosted lines. No status page found on eatthismuch.com, the docs or the partner page, and status.eatthismuch.com does not resolve (0). No readable incident history (5). Concurrency limits published with numbers, 3 week, 10 day and 20 meal generations per API user, but no rate per minute or day (12 of 15). 429 documented on three generate operations without Retry-After or backoff guidance, and no idempotency keys on calls that are charged (6 of 15). No SLA (0). The partner page calls the API early access with a limited number of partners, so not general availability (0). Total 23.); Nutritionix API 15 (Read with the hosted lines. The docs name a status page at status.nutritionix.com, but that host's robots.txt disallows our reader, so it is scored as unread (0 of 20) with no incident history (5). No rate limit figure appears anywhere in the docs (0 of 15). No 429, Retry-After or backoff guidance; the error page files 'usage limits exceeded' under 401 (0 of 15). No SLA found (0). The v2 API is generally available (10). 0 + 5 + 0 + 0 + 0 + 10 = 15.)
