Published price
Dev Pass: USD 9.99/month with 1,000 API calls. Public pricing lists SMME Pass at USD 49.99/month with 10,000 calls; plan documentation instead lists USD 49/month. Confirm at checkout. Enterprise is quoted, with 500,000+ calls described. These are subscription allowances, not token or marginal per-call rates.Source for Published price (opens in a new tab)
Pricing discrepancy
SMME price differs between public pricing (USD 49.99) and plan docs (USD 49). Enterprise marketing says no rate limits; technical plan docs say custom limits. Do not infer unlimited concurrency or an unconditional request quota.Source for Pricing discrepancy (opens in a new tab)
Request quotas
Per project: Free and Dev 60 requests/minute; SMME 120/minute; Enterprise custom. Keys in one project share quotas. Free allowance is 100 calls/month; monthly limits reset on the first day UTC. Only successful calls count for billing.Source for Request quotas (opens in a new tab)

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

API model ID
Not collected

Routes select languages or product features rather than exposing an immutable model ID.

Access
POST https://api.lelapa.ai/v1/transcribe/sync. X-CLIENT-TOKEN authentication; documented keys expire after 90 days. Set lang_code=sot.
Regions
Model-specific processing location not established in reviewed sources.

Data & enterprise terms

The May 2026 privacy notice says client data is not used for model training. Audio and transcripts follow the customer data-processing agreement; processing logs follow a separate retention policy. No universal numerical retention period or zero-retention guarantee is published. Service subprocessors are covered by data-processing agreements. Software rights remain with Lelapa; customers retain rights to outputs.

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

The provider model card explicitly identifies proprietary model weights or a proprietary fine-tuned derivative. Current language routes may use newer unnamed checkpoints; catalog family labels are not invented API model IDs.
