GET /api/v1/status

A summary of price accuracy: counts by status and the offers currently being checked or flagged as suspicious.

Response fields

Status values

• accurate — the price passed our validation and cross-provider checks.
• checking — the price looked unusual and is being verified against the source.
• suspicious — the price moved sharply or sits far from its peers; treat with care.

Rate limits

The free plan allows 1,000 requests / month. Every response carries X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset (the UTC reset time). Over the limit you get 429 with a Retry-After header.

Errors

Errors share one shape, with an HTTP status and a machine-readable code.

{
  "error": {
    "code": "INVALID_API_KEY",
    "message": "The API key is invalid."
  }
}
