Nutritionix API
by Syndigo LLC HTTP API in Cooking, recipes & meal planning
Syndigo LLC · nutritionix.com since 2010 · status page · who's behind it
The Nutritionix API, run by Syndigo, turns free-text food and exercise descriptions into nutrition data and searches a database of grocery products, restaurant menu items and generic foods by name or UPC. Access is arranged through Syndigo's sales team.
Best for Agents that log meals from free text for a US or UK audience and need branded grocery and restaurant nutrition with UPCs, under a sales contract.
Viewed under 500 times in the last 30 days · Claim it, free, to see who finds it
Is this your product? Claim it to see how agents find it: lookups through the API, MCP and letme, the comparisons it's in, and what people search for in Cooking. Free, and it never changes the grade. Or verify it, or log in if it's already claimed.
Assessment. Free-text food logging and a branded-food and restaurant database behind four header-authenticated endpoints, documented in Markdown with an llms.txt index and backed by Syndigo's sub-processor list and disclosure programme. There is no public price or free tier since the open trial ended, no documented rate limit or 429, and the status, terms and pricing pages are closed to our reader.

From our research 9 facts checked against the vendor's pages
- Surface listed
- The Nutritionix API v2 at trackapi.nutritionix.com, read from developer.nutritionix.com, the Nutritionix pages on docx.syndigo.com (API guide, headers, keys, errors, FAQs, natural nutrients, instant, data sync), Syndigo's about, privacy, terms, security, disclosure and sub-processor pages and the GitHub API on 3 November 2026. No account was made and no call was sent
- Endpoints
- POST /v2/natural/nutrients, GET /v2/search/instant, /v2/search/item, POST /v2/natural/exercise. The docs index also lists a Photo Upload API page, not read
- Natural nutrients
- Body fields query (required), num_servings, line_delimited, use_raw_foods, include_subrecipe, timezone, consumed_at, use_branded_foods, ingredient_statement, last_modified, and the premium taxonomy flag. Each food returns serving quantity, unit and weight, alt_measures, nf_* summary nutrients and full_nutrients as attr_id and value pairs
- Instant search
- query (required), branded, brand_ids, branded_type (1 restaurant, 2 grocery), branded_region (1 US, 2 UK), common and its grocery and restaurant subsets; premium claims, claims_query, taxonomy, taxonomy_node_id and detailed_nutrients (up to 3). At most 20 common and 20 branded results
- Premium add-ons
- detailed, branded_region, claims, claims_query, taxonomy and taxonomy_node_id on instant, taxonomy and claims on natural nutrients, sold through a Syndigo account executive
- Errors
- 400 validation, 401 unauthorised (invalid keys, usage limits exceeded, missing token), 403, 404, 409, 500. No body format documented
- Caching
- Pre-approved only for recording a user's own historical food log; cached data from one user may not be shown to another; other needs through support@nutritionix.com as a premium add-on. A CSV export of active items supports a local sync for licensed customers
- Libraries
- developer.nutritionix.com lists only the jQuery nutrition-label widget (github.com/nutritionix/nutrition-label, MIT, 192 stars, last push 3 June 2024). The nutritionix GitHub organisation also holds library-python (last push December 2022) and vue-nutrition-label (February 2026)
- Ownership
- Syndigo LLC, Chicago, hosts the docs, support and sub-processor list for the Nutritionix API, and its blog names Daniel Zadoff as Managing Director of Syndigo Nutrition & Wellness and founder of Nutritionix
Facts verified 3 November 2026 from vendor docs, repositories and package registries. JSON · Markdown
Strengths
- POST /v2/natural/nutrients parses phrases such as '1 cup rice' into serving weights, 11 summary nutrients and a full nutrient array in one call
- Branded foods, restaurant menu items and UPC lookup, with brand, region and claim filters on the instant endpoint
- Keys travel only in headers, with a per-user header that keeps billing off the key itself
- Markdown docs with an llms.txt index on Syndigo's portal, with examples per endpoint
- Syndigo names the Nutritionix API's sub-processors with locations and runs a responsible disclosure programme on Bugcrowd
Weaknesses
- No public free tier or published price; a limited trial is granted by sales after a form on www.nutritionix.com
- No rate limit figure, 429 or Retry-After documented; exceeded usage is reported as 401
- The status page, API terms and pricing page sit on hosts whose robots.txt disallows our reader, so none was read
- The API guide's last update is 14 March 2024, with no changelog and no official SDK in current maintenance
- Caching is limited to a user's own food log; other caching needs a paid add-on
Before you call it notes for agents
- Do not plan on self-serve access; a person must request a trial through Syndigo's sales form, so ask for an existing app id and key before starting
- Send
x-app-idandx-app-keyas headers and setx-remote-user-idper end user (0 in development), since billing counts active users - Treat a 401 as either a bad key or an exhausted usage limit; the docs give no limit figure, so back off before retrying
- Debounce instant searches by 300 ms and send at least 3 characters, then pass
food_nameto natural/nutrients for common foods andnix_item_idto search/item for branded ones - Cache only a person's own logged results; cached data may not be shown to another user

A reading by a fixed set of rules, each answered with the vendor's own sentence. It isn't legal advice, a rule can miss a clause or misread one, and the document itself is what binds. How it's read and scored.
Syndigo LLC is the entity on syndigo.com's legal pages and the sub-processor list, which has a Nutritionix API section. The API's own terms are shown during signup on developer.nutritionix.com and on www.nutritionix.com, which was not read; the Syndigo terms of use linked here (last updated 22 January 2019) govern Syndigo's website and do not mention the API.
www.nutritionix.com/robots.txt, trackapi.nutritionix.com/robots.txt and status.nutritionix.com/robots.txt all disallow the whole site for ClaudeBot, anthropic-ai and Claude-Web among about 30 named crawlers, and carry a Content-Signal line of search=yes,ai-train=no,use=reference for everyone else. Nothing on those hosts was read, so the pricing page, the API terms and the status page are unchecked. developer.nutritionix.com/robots.txt has only comments and docx.syndigo.com allows all; syndigo.com disallows demo and private paths only.
Syndigo's privacy notice is effective 25 March 2026 and does not name Nutritionix. Syndigo's responsible disclosure notice takes reports through Bugcrowd without compensation. No security.txt on developer.nutritionix.com (404).
RDAP gives nutritionix.com a registration date of 25 January 2010.

Ownership Part of Syndigo LLC
Researched 3 November 2026 from public pages. Nutritionix is a unit of Syndigo LLC, so the founder is Nutritionix's and the executive is Syndigo's. Syndigo's blog post of 13 May 2025 names Daniel Zadoff as Managing Director of Syndigo Nutrition & Wellness and founder of Nutritionix; no page read names a co-founder, so the roster may be incomplete. Syndigo's about page lists Simon Angove (CEO), Abhi Ananth (CTO) and Tarun Chandrasekhar (CPO); its LinkedIn links are placeholders, so no personal accounts are listed. www.nutritionix.com is closed to our reader by robots.txt, so its own about and contact pages were not read. Syndigo is a subsidiary's parent here, so no investors are listed for Nutritionix; Syndigo's own press release of 16 December 2020 names Summit Partners and The Jordan Company as its investors. Shown for information, not part of the grade yet. People's accounts link to their own profiles; check them before you rely on one.

- Keys go in the

- The docs list six error statuses with one line each; 'usage limits exceeded' is a 401, and no 429, Retry-After or rate-limit number appears source
- Caching is pre-approved only for a user's own food log; cached data may not be shown to another user, and other caching needs a premium add-on through support@nutritionix.com source
- The docs are on Syndigo's portal with an llms.txt index and a Markdown twin of every page; the API guide was last updated on 14 March 2024 source
- Syndigo's sub-processor list, effective 13 April 2026, has a Nutritionix API section naming Amazon Web Services, Red Hat (3scale) and Cloudflare, all in the United States source
- A status page at status.nutritionix.com is named in the docs; its robots.txt disallows ClaudeBot and anthropic-ai, so it was not read, as were the terms and pricing pages on www.nutritionix.com (checked 2026-11-03)

Score breakdown methodology v0.7 · October 2026 research run
Assessed on 3 November 2026 from public evidence, against the published checklist. Confidence low. Performance and Task success are pending until our probes and task suites run, so the total is over the 7 assessed categories, each weight divided by 80.

| Reliabilitychecked 3 November 2026 | 16%20 | 3.0 | |
| 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).

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. | |||

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. | |||

An application id and key pair with no scopes, sent only as headers per the docs, which say not to use the query string; no expiry or rotation documented (18 of 30). The API is read-only, so nothing destructive is reachable, but there is no read-only or per-user credential (12 of 20). Food, brand and menu names come from brands and restaurants through Syndigo, with little free text and no guidance on treating it as untrusted (8 of 15). x-remote-user-id counts active users for billing; no request log or per-call visibility for the operator was found (2 of 15). Syndigo runs a responsible disclosure programme on Bugcrowd without compensation, holds SOC 2 Type II for named products that do not include Nutritionix, and lists the Nutritionix API's sub-processors; no security.txt (12 of 20). 18 + 12 + 8 + 2 + 12 = 52. | |||

Graded 33.6 F methodology v0.7
Fix list 18 items, the biggest gain first
Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Nutritionix API. A fix counts at the next check, once it's public.
You're lucky. As part of the beta, your first month is free.
What we couldn't check
- unchecked: the status page at status.nutritionix.com, the pricing page and the API terms on www.nutritionix.com, and anything on trackapi.nutritionix.com, because each host's robots.txt disallows ClaudeBot and anthropic-ai. Reliability, payments and transparency score them as absent, and the lander may hold the listing for that reason, as the 14 October brief did for yelp.
- The developer portal says the free-access tier has ended; whether a sign-up there still issues a usable key was not established.
- firstReleased is 6 December 2012, the creation date of the nutritionix GitHub organisation, the earliest dated first-hand signal found; the domain dates from 25 January 2010 and the portal says the open trial ran for over a decade. lastRelease is 14 March 2024, the API guide's last update.
- Ownership is recorded as a Syndigo subsidiary from Syndigo's own docs portal, support routing, sub-processor list and blog; no first-hand page gives the acquisition date, which secondary sources place in 2018.
- The llms.txt index lists a Photo Upload API page and a natural exercise page that were not read; the capabilities list leaves food recognition out for that reason.
- The official MCP registry lists a third-party io.github.mrfentmen/nutritionix-mcp 1.0.0 and nothing from the vendor.
- Content-Signal on the nutritionix.com hosts says ai-train=no and use=reference; recorded as a fact about the site.

Probe metrics
Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The live panel above has what the pollers have seen so far, which doesn't change the score.
Pricing & changes
Paid Paid No public price. developer.nutritionix.com says the open, no-cost trial that ran for over a decade has ended because of misuse, and that businesses request a limited trial through the contact form at www.nutritionix.com/business/api, after which sales follows up. The pricing page on www.nutritionix.com is closed to our reader by robots.txt. Premium parameters (claims, taxonomy, UK branded data, detailed nutrients) are sold separately through an account executive.

Agents send the same to POST /api/v1/verify as {"slug": "nutritionix", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.
