Superhero Rate Limits

The Superhero API does not publish explicit rate limit values. The service is free and community-maintained; access tokens are issued per GitHub account. Limits below represent reasonable-use estimates. Clients should implement backoff on HTTP 429 or 503 responses.

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

It captures 2 rate-limit definitions, across the free tier, measuring requests_per_minute and requests_per_day.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Superheroes, Comics, Characters, Entertainment, and Rate Limiting.

Policies

Token in URL
The access token is embedded directly in the request URL path (https://superheroapi.com/api.php/{access-token}/{id}). Keep tokens private; do not expose them in public repositories or client-side JavaScript.
GitHub Login Required
Obtain your access token by authenticating with GitHub at superheroapi.com. Tokens are personal and non-transferable.
Backoff Strategy
Implement exponential backoff with jitter when receiving 429 or 503 responses. Honor the Retry-After header when present.
Fair Use
The API is a free community resource. Sustained high-volume traffic or abusive request patterns may result in token revocation without notice.
