vehicle.profile

Vehicle 360 — decode a VIN and get its full safety picture in one call. Returns the decoded vehicle (make, model, year, trim, engine, plant, body class, drivetrain — NHTSA vPIC) plus that exact make/model/year's open safety recalls (with park-it / park-outside / over-the-air-update flags) and NHTSA owner complaints (crash/fire/injury/death flags). recalls and complaints are keyed to the decoded make+model+year, so they describe THIS vehicle, not a generic feed. Each section reports found/error independently. Pass vin (17 chars); optional modelYear disambiguates pre-1980 VINs. Used for used-car due diligence, fleet safety, insurance. Individual sources: /api/vehicle/vin-decode, /api/vehicle/recalls, /api/vehicle/complaints.

Code samples

cURLbash

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/vehicle/profile?vin=xxxxxxxxxxxxxxxxx&modelYear=1949'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/vehicle/profile?vin=xxxxxxxxxxxxxxxxx&modelYear=1949' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):

#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/vehicle/profile?vin=xxxxxxxxxxxxxxxxx&modelYear=1949'

// 1. Add @2sio/mcp to your MCP host config (Claude Desktop example below).
//    EVM_PRIVATE_KEY funds x402 payments per call.
