APIClaw — Amazon Seller Data Analysis

AI-powered Amazon product research. From market discovery to daily operations.
Language rule: Always respond in the user's language. If the user asks in Chinese, reply in Chinese. If in English, reply in English. The language of this skill document does not affect output language.
All API calls go through scripts/apiclaw.py — one script, 5 endpoints, built-in error handling.

Credentials

• - Required: INLINECODE1
• Scope: used only for INLINECODE2
• Resolution order:

1. Environment variable APICLAW_API_KEY (preferred, most secure) 2. Config file config.json in the skill root directory (fallback)

CODEBLOCK0

When user provides a Key, write it to config.json. New keys may need 3-5 seconds to activate — if first call returns 403, wait 3 seconds and retry (max 2 retries).

File Map

File	When to Load
INLINECODE6 (this file)	Start here — covers 80% of tasks
INLINECODE7

Execute for all API calls (do NOT read into context) | | references/reference.md | Need exact field names or filter parameter details | | references/scenarios-composite.md | Comprehensive recommendations (2.10) or Chinese seller cases (3.4) | | references/scenarios-eval.md | Product evaluation, risk assessment, review analysis (4.x) | | references/scenarios-pricing.md | Pricing strategy, profit estimation, listing reference (5.x) | | references/scenarios-ops.md | Market monitoring, competitor tracking, anomaly alerts (6.x) | | references/scenarios-expand.md | Product expansion, trends, discontinuation decisions (7.x) | | references/scenarios-listing.md | Listing writing, optimization, content creation (8.x) |

Don't guess field names — if uncertain, load reference.md first.

Execution Mode

Task Type	Mode	Behavior
Single ASIN lookup, simple data query	Quick	Execute command, return key data. Skip evaluation criteria and output standard block.
Market analysis, product selection, competitor comparison, risk assessment

Full | Complete flow: command → analysis → evaluation criteria → output standard block. |

Quick mode trigger: User asks for a single specific data point ("B09XXX monthly sales?", "how many brands in cat litter?") — no decision analysis needed.

⚠️ Pre-Execution Checklist (MANDATORY for Full Mode)

Before running any Full-mode product selection or market analysis, complete this checklist:

• - [ ] Step 1 — Mode Selection: Check the Product Selection Mode Mapping table below. If ANY of the 14 preset modes matches the user's intent, USE IT (--mode xxx). Do NOT manually piece together filters when a preset mode exists. Common mappings:

- Small/lightweight/cheap products → --mode low-price - New seller / beginner → --mode beginner - Niche / long-tail → --mode long-tail - Trending / rising → --mode emerging

• - [ ] Step 2 — Realtime Supplement: Plan to call product --asin for the top 3-5 ASINs from results (see Realtime Data Supplementation below).
• [ ] Step 3 — Review Analysis: Plan to call analyze --asins for top ASINs to get consumer insights (especially painPoints, improvements, buyingFactors).
• [ ] Step 4 — Output Blocks: Prepare to include both 📋 Data Source & Conditions and 📊 API Usage at the end.

Why this exists: In testing, AI agents repeatedly skipped preset modes, realtime supplements, and review analysis — even though the instructions below clearly describe them. This checklist forces a pause-and-verify before execution.

---

Execution Standards

Prioritize script execution for API calls. The script includes:

• - Parameter format conversion (e.g. topN auto-converted to string)
• Retry logic (429/timeout auto-retry)
• Standardized error messages
• INLINECODE25 metadata injection (for query traceability)

Fallback: If script fails and can't be quickly fixed, use curl directly. Note "using curl direct call" in output.

---

Realtime Data Supplementation

When products or competitors returns ASINs in Full-mode analysis, automatically call product --asin for the top 3-5 most relevant ASINs to get current real-time data.

Scenario	Supplement?	How many ASINs
Single ASIN lookup (Quick mode)	Already using realtime	—
Market overview (no specific ASINs)

❌ No | — |
| Product selection / competitor analysis | ✅ Yes | Top 3 by sales |
| Risk assessment | ✅ Yes | Target ASIN + top 2 competitors |
| Multi-product comparison | ✅ Yes | All compared ASINs (max 5) |
| Listing analysis | Already using realtime | — |

Handling data conflicts — products/competitors has ~T+1 delay; realtime/product is live:

Field	Use from	Reason
Price	realtime (buyboxWinner.price)	Changes frequently
BSR

realtime (bestsellersRank) | Updates hourly |
| Rating / ratingCount | realtime | More current |
| Monthly Sales | products/competitors | Realtime doesn't have this |
| Profit Margin / FBA Fee | products/competitors | Realtime doesn't have this |

When realtime data differs significantly, note it: e.g. "⚡ Price updated: database $29.99 → realtime $24.99 (likely promotion)"

---

Script Usage

All commands output JSON. Progress messages go to stderr.

categories — Category tree lookup

CODEBLOCK1

Common fields: categoryName (not name), categoryPath, productCount, INLINECODE38

market — Market-level aggregate data

CODEBLOCK2

Key output fields: sampleAvgMonthlySales, sampleAvgPrice, topSalesRate (concentration), topBrandSalesRate, sampleNewSkuRate, sampleFbaRate, INLINECODE45

products — Product selection with filters

CODEBLOCK3

Available modes: fast-movers, emerging, single-variant, high-demand-low-barrier, long-tail, underserved, new-release, fbm-friendly, low-price, broad-catalog, selective-catalog, speculative, beginner, INLINECODE59

Keyword matching: Default is fuzzy (matches brand names too — e.g. "smart ring" matches "Smart Color Art" pens). Use --keyword-match-type exact or phrase for precise results. Always combine with --category when possible to reduce noise.

Category path with commas: Some category names contain commas (e.g. "Pacifiers, Teethers & Teething Relief"). Use > separator instead of , to avoid parsing errors:
CODEBLOCK4

competitors — Competitor lookup

CODEBLOCK5

Easily confused fields (products/competitors shared):

❌ Wrong	✅ Correct	Note
INLINECODE66	INLINECODE67	Review count
INLINECODE68

bsrRank | BSR ranking (integer, only in products/competitors) |
| monthlySales / salesMonthly | atLeastMonthlySales | Monthly sales (lower bound estimate, NOT in realtime/product) |
| bestsellersRank | bsrRank | bestsellersRank is realtime/product only (array format); use bsrRank for products/competitors |
| price (in realtime) | buyboxWinner.price | realtime/product nests price inside buyboxWinner object |
| profitMargin (in realtime) | ❌ N/A | realtime/product does NOT return profitMargin; use products/competitors |

Complete field list: reference.md → Shared Product Object

product — Single ASIN real-time detail

CODEBLOCK6

Returns: title, brand, rating, ratingBreakdown, features, topReviews, specifications, variants, bestsellersRank, buyboxWinner

analyze — Review analysis (sentiment + consumer insights)

CODEBLOCK7

Returns: totalReviews, avgRating, sentimentDistribution, ratingDistribution, consumerInsights (by labelType), topKeywords, INLINECODE87

Available labelType: scenarios, issues, positives, improvements, buyingFactors, painPoints, keywords, userProfiles, usageTimes, usageLocations, INLINECODE98

report — Full market analysis (composite)

CODEBLOCK8

Runs: categories → market → products (top 50) → realtime detail (top 1).

opportunity — Product opportunity discovery (composite)

CODEBLOCK9

Runs: categories → market → products (filtered) → realtime detail (top 3).

⚠️ Interface Data Differences

The 4 types of interfaces return different fields. Do NOT assume they share the same structure.

Data	INLINECODE99	INLINECODE100/INLINECODE101	INLINECODE102	INLINECODE103
Monthly Sales	INLINECODE104	✅ INLINECODE105	❌	❌
Revenue

sampleAvgMonthlyRevenue | salesRevenue | ❌ | ❌ |
| Price | sampleAvgPrice | price | buyboxWinner.price | ❌ |
| BSR | sampleAvgBsr | bsrRank (integer) | bestsellersRank (array) | ❌ |
| Rating | sampleAvgRating | rating | rating | avgRating |
| Review Count | sampleAvgReviewCount | ratingCount | ratingCount | totalReviews |
| Review Details | ❌ | ❌ | ✅ topReviews + ratingBreakdown | ❌ (no raw reviews) |
| Sentiment Analysis | ❌ | ❌ | ❌ | ✅ sentimentDistribution |
| Consumer Insights | ❌ | ❌ | ❌ | ✅ consumerInsights (11 dimensions) |
| Pain Points/Issues | ❌ | ❌ | ❌ (manual from topReviews) | ✅ AI-analyzed |
| Top Keywords | ❌ | ❌ | ❌ | ✅ topKeywords |
| Seller | ❌ | buyboxSeller (string) | buyboxWinner (object) | ❌ |
| Profit Margin | ❌ | profitMargin | ❌ | ❌ |
| FBA Fee | ❌ | fbaFee | ❌ | ❌ |
| Seller Count | ❌ | sellerCount | ❌ | ❌ |
| Features/Bullets | ❌ | ❌ | ✅ features | ❌ |
| Variants | ❌ | variantCount (integer) | variants (full list) | ❌ |

Usage rule:

• - Use products / competitors for sales, pricing, and competition data
• Use realtime/product for review details, listing content, and seller info
• Use market for category-level aggregate metrics
• Use reviews/analyze for AI-powered review insights (sentiment, pain points, buying factors — covers all reviews, not just topReviews)
• For reports: combine products/competitors (quantitative) + realtime/product (qualitative) + reviews/analyze (consumer insights) as evidence

Data Structure Reminder

All interfaces return .data as an array. Use .data[0] to get the first record, NOT .data.fieldName.

⚠️ Output Standards (Full Mode — MANDATORY, DO NOT SKIP)

Two blocks are REQUIRED at the end of every Full-mode analysis: ① Data Source & Conditions, ② API Usage. Missing either one = violating the skill contract.

① Data Source & Conditions (Full Mode Only)

CODEBLOCK10

Rules:

1. 1. Every Full-mode analysis MUST end with this block
2. Filter conditions MUST list specific parameter values
3. If multiple interfaces used, list each one
4. If data has limitations, proactively explain
5. ⚠️ Self-check: scan your response — if you don't see 📋 **Data Source & Conditions**, ADD IT before replying

⚠️ API Usage Summary (All Modes — MANDATORY, DO NOT SKIP)

This block is NON-NEGOTIABLE. Every single response — Quick or Full mode — MUST end with this table. No exceptions. If you forget, you are violating the skill contract.

CODEBLOCK11

Tracking rules:

1. 1. Count each apiclaw.py execution as 1 call to the corresponding interface
2. Sum _credits.consumed from every API response for total consumed
3. Use _credits.remaining from the last API response as remaining balance
4. If _credits fields are null, show "N/A"
5. ⚠️ Self-check before sending: scan your response — if you don't see 📊 **API Usage** at the bottom, ADD IT before replying

Limitations

What This Skill Cannot Do

• - Keyword research / reverse ASIN / ABA data
• Traffic source analysis
• Historical sales trends (14-month curves)
• Historical price / BSR charts
• Raw individual review text export (use realtime/product topReviews for specific review quotes)

API Coverage Boundaries

Scenario	Coverage	Suggestion
Market data: Popular keywords	✅ Has data	Use --keyword directly
Market data: Niche/long-tail keywords

⚠️ May be empty | Use --category instead | | Product data: Active ASIN | ✅ Has data | — | | Product data: Delisted/variant ASIN | ❌ No data | Try parent ASIN or realtime | | Real-time data: US site | ✅ Full support | — | | Real-time data: Non-US sites | ⚠️ Partial | Core fields OK, sales may be null |
