Chartmetric Rate Limits

Chartmetric enforces per-account request-rate limits on its REST API expressed as requests per second (RPS). Entry-level Developer API access is reported at 1 request per second, with higher ceilings (up to ~25 requests per second documented) available under scaled and enterprise agreements. Access tokens are short-lived (1 hour) and must be refreshed via POST /api/token; the same access token should be reused across calls until it expires rather than minted per request. Specific per-account values are not reconciled in this artifact.

Chartmetric Rate Limits is the machine-readable rate-limit profile for Chartmetric on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring requests and seconds.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Music, Analytics, Artist Intelligence, Streaming, and Charts.

Policies

Tiered Limits
Request-rate ceilings increase from entry (1 RPS) to scaled / enterprise (up to ~25 RPS) under negotiated agreements.
Token Reuse
Mint one access token from the refresh token and reuse it across requests until it expires; do not request a new token per call.
Backoff Strategy
Clients should implement exponential backoff with jitter on HTTP 429 responses and honor any Retry-After header.
