## Which one, for what

### Amazon Creators API (D)

Good for: Product search, price checks and affiliate links for an agent that recommends Amazon products and hands the purchase to the person.

Ahead on:
- Reliability, 45 against 19
- Agent ergonomics, 85 against 69
- Security & auth, 48 against 26
- Maintenance & community, 41 against 6
- Transparency & trust, 53 against 47

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No order, cart, checkout, order status or return operation

### MealMe API (E)

Good for: Agents that must place a real restaurant or grocery order in the US or Canada, or compare live prices across stores, and can hold a card on the account.

Ahead on:
- Schema & documentation, 72 against 50
- Payments & pricing, 20 against 10

Watch for: One key with no scopes, read-only mode, expiry or rotation documented, sent in a custom Id-Token header


## Why the edge

### Maintenance & community: Amazon Creators API +35

- Amazon Creators API (41): The latest dated change is SDK 1.3.0 on 21 August 2026, 54 days ago (20 of 30). Only one dated entry falls in the last 90 days (0 of 20). Support is through the Associates contact form, which promises a reply to acceptance requests in 3 to 4 days, and there is no public API changelog or forum (8 of 15). Official SDKs in four languages are current to August 2026, but none is published on npm, PyPI, Packagist or Maven by Amazon (10 of 15). The npm names creatorsapi-nodejs-sdk and amazon-creators-api are held by individuals, and no CI or dependency status is public (3 of 10). Total 41.
- MealMe API (6): Read as a closed service. The newest dated change is the release note of 6 May 2025 (Get Inventory v4), more than 180 days before 3 November 2026; the pricing and dashboard pages carry no date (0 of 30). No dated change in the last 90 days (0 of 20). A support address, release notes and no community channel (6 of 15). No official SDKs (0). No package to judge (0). Total 6.

### Reliability: Amazon Creators API +26

- Amazon Creators API (45): No status page for the Creators API was found in the documentation (0 of 20). No readable incident history, so the line takes the 5-point default (5 of 30). Rate limits are published with numbers, 1 request a second and 8,640 a day at the start, then scaled by shipped revenue up to 10 a second (15 of 15). 429 ThrottleException and 500 InternalServerException both tell clients to retry with exponential backoff, errors can carry retryAfterSeconds, and every operation is a read, so retries are safe (15 of 15). No SLA (0 of 10). The API is the supported successor to PA-API 5 and generally available (10 of 10). Total 45.
- MealMe API (19): Read with the hosted lines. No status page found on mealme.ai, the docs or llms.txt, and status.mealme.ai does not resolve (0). No readable incident history (5). No rate limit figures; each endpoint documents a 429 whose example message is 10 per 1 second(s)!, which the reference itself calls an example (0 of 15). The 429 is documented without Retry-After or backoff guidance, and Create Order has no idempotency key, only an order_id to update an existing order and a caller's customer_order_id to look up (4 of 15). No SLA found (0). The API is in production with versioned endpoints (10). Total 19.

### Schema & documentation: MealMe API +22

- Amazon Creators API (50): No public OpenAPI or other machine-readable description was found. The SDKs are generated archives behind a download (0 of 25). No llms.txt (/creatorsapi/docs/llms.txt returns 404) and no Markdown twins (0 of 10). Each operation page states its purpose, the parameters that apply to which search indices and when to use a browse node instead of a keyword, without when-not-to-use guidance (14 of 20). Parameters are typed with defaults, ranges (itemCount and itemPage 1 to 10) and required markers, and resources are a fixed enum of dot paths (12 of 15). Examples in cURL and JSON for each operation, and an error page listing every exception with its reason codes and example messages (14 of 15). The API version is in the path (v1) and the SDK changelog is dated, but there is no changelog for the API itself (10 of 15). Total 50.
- MealMe API (72): The reference pages are generated from an API description with operation ids (get_search_store_v3), named response schemas (Product_Search_Output) and typed parameters, but no spec file URL was found on the docs, llms.txt or the site (15 of 25). llms.txt at mealmeapi.readme.io and mealme.ai, and every page as Markdown (10). Each operation states its purpose and coverage; several descriptions are truncated in the index and none says when not to use it (12 of 20). Enums on sort, store_type, user_country and search_focus, required flags on latitude and longitude, conditional requirements written in prose (11 of 15). Request and response examples per endpoint, a Create Order errors page with 17 entries, and 400, 401 and 429 schemas on each operation (12 of 15). Versioned paths (v2 to v4) and dated release notes that call out breaking changes, the newest of 6 May 2025 (12 of 15). Total 72.

### Security & auth: Amazon Creators API +22

- Amazon Creators API (48): OAuth 2.0 client credentials with tokens that last one hour. Two credentials per application allow rotation, and credentials can be deleted, but there is one scope (creatorsapi::default) and no finer permissions (22 of 30). The API is read-only, so an agent cannot spend money or change an account through it (18 of 20). It returns product titles and feature bullets written by sellers, with no guidance on treating them as untrusted data (5 of 15). The operator sees attributed sales in the Link Type Performance report, not a per-call log (3 of 15). Programme not established. security.txt on www.amazon.com was not read because robots.txt disallows our crawler, affiliate-program.amazon.com has none (404), and the HackerOne page for Amazon's programme did not render, so no point was given (0 of 20). Total 48.
- MealMe API (26): One API key per account in a custom Id-Token header, with no scopes, expiry, rotation or revocation documented (10 of 30). place_order defaults to false and charge_user can be turned off, so an agent can quote without buying, but there is no read-only key (8 of 20). Store descriptions, menus and support-chat messages are untrusted content with no guidance (3 of 15). Get Orders and a tracking webhook give order history; no per-call log for the operator is documented (5 of 15). No security.txt (400), disclosure policy, bug bounty or certification found; the Enterprise plan names a security review (0 of 20). Total 26.

### Agent ergonomics: Amazon Creators API +16

- Amazon Creators API (85): The resources parameter returns only the fields requested, and the best practices recommend it to cut payload size (22 of 25). SearchItems pages up to 10 items with itemPage 1 to 10, so 100 results at most, with filters for brand, price range, condition, availability, delivery flags, merchant and sort (17 of 20). Errors have a type, a machine-readable reason, fieldList for validation failures and retryAfterSeconds where relevant, and partial results return an errors array per item (18 of 20). All four operations are reads and safe to retry, though no idempotency mechanism is needed or named (15 of 20). Sensible defaults (search index All, availability Available, itemCount 10) and official SDKs in four languages, though only as archive downloads (13 of 15). Total 85.
- MealMe API (69): Store search takes a projections list to choose response fields and a fetch_quotes switch that the docs say greatly increases response time, so responses can be sized (20 of 25). Page and next_page pagination, bounding-box, distance, rating, price, cuisine and open filters, maximum_miles defaults (18 of 20). Distinct status codes, 406 for a closed or out-of-range store, 420 for an unavailable product, 422 for checkout errors, each with a message naming the field or product (16 of 20). No idempotency key; the two-step order (202 quote, then place) and customer_order_id lookup are the safe-retry route (8 of 20). Only latitude and longitude required for search and sensible defaults, but no official SDK in any language, only an iframe embed (7 of 15). Total 69.

### Payments & pricing: MealMe API +10

- Amazon Creators API (10): No x402, MPP or L402 (0 of 40). The documentation states no fee for API calls, and usage limits are tied to referred revenue, not a price list. Nothing says the API is free in plain terms, so half the line (10 of 20). There is no free tier in the usual sense. Access needs an accepted Associates account and 10 qualifying sales in the trailing 30 days, so a new developer cannot start (0 of 20). Associates signup, final acceptance and credential creation all happen in a browser by the primary account owner (0 of 20). Total 10.
- MealMe API (20): No x402, MPP or L402 (0). $0.10 per successful call and $250 a month published without login (20). No free tier or trial; a card must be added before the key is created (0). Signup is a browser form with email, password and card (0). Total 20.

## Verdicts

**Amazon Creators API.** Read-only product search and lookup across 22 Amazon stores, with field selection, typed error reasons and documented rate limits. It cannot place or follow orders, so a person buys through the affiliate link. Access needs an accepted Associates account with 10 qualifying sales in 30 days, and the Agent Terms require agents to identify themselves.

**MealMe API.** An agent can search stores and products, fetch live quotes and place a real order through one REST API priced at $0.10 a successful call. One all-powerful key, no rate limit figures, no status page, no idempotency key on orders and release notes that stop at 6 May 2025 are the limits.

## Before you call either

### Amazon Creators API

1. Send x-marketplace as a header and marketplace and partnerTag in the body on every call
2. Cache the access token for its 3,600 seconds and share it across processes
3. Request only the resources the task needs, and use offersV2 for prices, because the older price resource is gone
4. Set the user agent to Agent/<name> as the Associates Agent Terms require
5. Hand purchases to the person through the returned detailPageURL without editing its parameters

### MealMe API

1. Send the key as the Id-Token header, not Authorization. Only latitude and longitude are required for store search; address fields become required when fetch_quotes is true and pickup is false
2. Call Create Order with place_order false first, read the 202 final quote, then place it; keep your own customer_order_id and look it up before any retry, since no idempotency key exists
3. Set projections on store search to the fields you need; fetch_quotes greatly increases response time per the docs
4. Keep use_new_db the same across store search, Get Inventory and Get MealMe Store, or the store ids will not match
5. Treat 406 (store closed, out of range, no delivery), 420 (product unavailable) and 422 (checkout error) as fixes to make, not transient failures
