Langtrace AI · Rate Limits

Langtrace Rate Limits

Langtrace does not publish explicit per-endpoint request rate limits for its REST API. The practical ceiling on Langtrace Cloud is the span allowance of the active plan (monthly/annual span quotas), rather than RPM/TPM throttles. The trace retrieval endpoint caps pageSize at 100 traces per request, which bounds read pagination. Self-hosted deployments are limited only by the capacity of the operator's own infrastructure. Specific throttle values are not reconciled in this artifact.

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

It captures 4 rate-limit definitions, measuring traces, spans, and requests.

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

Tagged areas include AI, LLM, Observability, OpenTelemetry, and Tracing.

Limits

Trace Retrieval Page Size request

POST /api/traces caps pageSize at 100 traces per page.
Cloud Span Allowance account
spans
see plan / provider documentation
Span quota per Cloud plan (e.g., Free monthly cap, Growth annual cap) acts as the usage ceiling.
Ingestion Rate account
spans
see provider documentation
No published per-second ingestion throttle; bounded by plan span allowance on Cloud.
Self-Hosted deployment

operator infrastructure capacity
Self-hosted deployments have no provider-imposed rate limit.

Policies

Span-Based Quotas
Cloud usage is governed by span allowances per plan rather than request-per-minute throttles.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After if a 429 is returned.
