Vehicle intelligence for AI agents — decode any 17-char VIN with a factory-warranty-terms block, MERGED US (NHTSA) + Canada (Transport Canada) recalls, LLM-clustered known issues with ODI citations plus a reliability-aggregates block, and itemized used-car drive-away costs for all 50 US states + DC and all 13 Canadian jurisdictions. Pay-per-call via x402 (USDC on Base); no accounts, no keys. Free /v1/sample/* endpoints return every response shape before you pay.

Auto.dev
Automotive data for AI agents — via MCP tools, CLI commands, SDK methods, or direct API calls.
Detect Your Surface
Check in this order. Use the first one available:
1. MCP — Check if auto_decode is in your available tools.
If yes: use auto_* tools for everything. Do NOT make raw HTTP calls.
To install: npx @auto.dev/sdk mcp install (installs globally and configures Claude Code, Claude Desktop, Cursor, Windsurf, VS Code Copilot, Cline, Zed).
2. CLI — Run auto --version.
If installed: authenticate once with auto login (OAuth — no API key needed), then use auto commands.
To install: npm install -g @auto.dev/sdk or use npx @auto.dev/sdk without installing.
3. SDK — Check if @auto.dev/sdk is in project dependencies.
If yes: use typed SDK methods. See code-patterns.md for all methods.
To install: npm install @auto.dev/sdk
4. Direct API — Check for AUTODEV_API_KEY env var.
If not set: ask the user for it or direct them to https://auto.dev/pricing (free Starter plan).
MCP Tools
If MCP tools are available, this is your only section. Use auto_docs to look up
parameters and response shapes before calling an unfamiliar endpoint.
auto_docs listings # see all listing filters
auto_docs payments # see payment params
auto_docs vin-decode # see VIN decode response shape
| Tool | Description | Plan |
|---|---|---|
auto_decode | Decode a VIN | Starter |
auto_listings | Search listings with filters | Starter |
auto_photos | Get vehicle photos | Starter |
auto_specs | Vehicle specifications | Growth |
auto_build | OEM build data ($0.10/call) | Growth |
auto_recalls | Safety recalls | Growth |
auto_payments | Payment calculations | Growth |
auto_apr | Interest rates | Growth |
auto_tco | Total cost of ownership | Growth |
auto_open_recalls | Open/unresolved recalls | Scale |
auto_plate | Plate to VIN ($0.55/call) | Scale |
auto_taxes | Taxes and fees | Scale |
auto_docs | Search bundled API documentation | — |
auto_config_set | Set a config value (e.g. raw: true) | — |
auto_config_get | Get a config value or list all settings | — |
API metadata is stripped from MCP tool responses by default. Use auto_config_set with key: "raw" and value: "true" to get full responses.
If MCP tools are available, skip to Important Rules below.
CLI Quick Reference
Install: npm install -g @auto.dev/sdk (or use npx @auto.dev/sdk without installing)
Authenticate once: auto login
auto decode
auto photos
auto listings --make Toyota --year 2024 --price 10000-40000 --state CA
auto specs
auto build
auto recalls
auto open-recalls
auto payments --price 35000 --zip 90210 --down-payment 5000
auto apr --year 2024 --make Honda --model Accord --zip 90210 --credit-score 750
auto tco --zip 90210
auto taxes --price 35000 --zip 90210
auto plate
auto usage
auto docs [query] # search bundled docs
auto explore [endpoint] # browse params and mappings
All commands support --json, --yaml, --raw, and --api-key flags.
API metadata is stripped by default — you get clean vehicle data. Use --raw to see the full API response.
auto config set raw true # always show full responses
auto config get raw # check current value
auto config list # show all settings

Direct API Quick Reference
Use these only when MCP and CLI are unavailable.
V2 (base: https://api.auto.dev): Authorization: Bearer {key} or ?apiKey={key}
V1 (base: https://auto.dev/api): ?apikey={key} (query string only)
| Endpoint | Plan | Required Params |
|---|---|---|
GET /listings?filters | Starter | See v2-listings-api.md |
GET /listings/{vin} | Starter | — |
GET /vin/{vin} | Starter | — |
GET /photos/{vin} | Starter | — |
GET /specs/{vin} | Growth | — |
GET /build/{vin} | Growth | — ($0.10/call) |
GET /recalls/{vin} | Growth | — |
GET /tco/{vin} | Growth | — |
GET /payments/{vin} | Growth | price, zip |
GET /apr/{vin} | Growth | year, make, model, zip, creditScore |
GET /openrecalls/{vin} | Scale | — |
GET /plate/{state}/{plate} | Scale | — ($0.55/call) |
GET /taxes/{vin} | Scale | — |
V1 supplemental (no V2 equivalent): /api/models, /api/cities, /api/zip/{zip}, /api/autosuggest/{term}
Before making any Direct API call, read the relevant reference file for full parameter names and examples. Full parameter reference: v2-listings-api.md | v2-vin-apis.md | v2-plate-api.md | v1-apis.md
Common Gotchas (All Surfaces)
These parameter names do NOT exist on the Direct API — agents hallucinate them frequently:
make= ← use vehicle.make
model= ← use vehicle.model
state= ← use retailListing.state
price= ← use retailListing.price (on /listings), or price= (on /payments, /taxes)
rows= ← use limit
sort= ← no sort parameter exists
_order= ← no sort parameter exists
MCP and CLI handle these mappings automatically. This only matters for Direct API calls.
Plans & Pricing
See pricing.md for full per-call costs and upgrade links.
| Plan | Monthly | Includes |
|---|---|---|
| Starter | Free + data fees | VIN Decode, Listings, Photos (1,000 free calls/mo) |
| Growth | $299/mo + data fees | + Specs, Recalls, TCO, Payments, APR, Build |
| Scale | $599/mo + data fees | + Open Recalls, Plate-to-VIN, Taxes & Fees |
All plans charge per-call data fees on every request. Growth/Scale have no cap on volume but data fees still apply.
Important Rules
- Before batch operations, call the endpoint once with a single item to see the actual response shape. Do not guess field names or nesting — inspect the real response first.
- Include ALL fields from the API response unless the user explicitly says to exclude some.
- Small results (<10 items, single VIN): Display inline as formatted table
- Large results (10+ listings): Ask user preference, default to CSV export
- Always support: CSV, JSON export when user requests
- Chain APIs when the query spans multiple endpoints — MCP tools and CLI commands can be called in parallel
Deep Reference
MCP or CLI: use auto_docs [query] or auto docs [query] for live parameter lookup.
