Singularity Energy Rate Limits

The Singularity Grid Carbon API authenticates requests with an X-Api-Key header (a User-Agent header is also required) and paginates region-event searches via page / per_page parameters. Singularity does not publish specific numeric request-per-minute or per-day rate limits in its public documentation; quotas are governed by the per-region subscription and negotiated commercial terms. Specific throttling values are not reconciled in this artifact.

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

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

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Energy, Carbon Emissions, Grid, Sustainability, and Carbon Intensity.

Policies

Data Lag
Carbon intensity and fuel mix lag roughly 1 hour for major ISOs and up to 24 hours for non-real-time balancing authorities.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on HTTP 429 responses.
