Highlight Io Rate Limits

Reconciled ingestion limits for the Highlight hosted offering. Limits apply at the project level on the public ingestion endpoint (`pub.highlight.io`) and the OTLP endpoints (`otel.highlight.io`). Self-hosted deployments may configure their own limits in the OpenTelemetry Collector and Kafka tiers.

Highlight Io Rate Limits is the machine-readable rate-limit profile for Highlight (highlight.io) on the APIs.io network, in the API Commons Rate Limits shape.

It captures 7 rate-limit definitions, across the Free, Pay-as-you-go, Business, Enterprise, and All tiers.

Limit state is signalled in the retryAfter response header, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled and payloadTooLarge.

Tagged areas include Observability, Rate Limiting, and Ingestion.
