Mono Co Rate Limits

Mono enforces per-application throttling on its REST API, scoped by the secret application key passed in the mono-sec-key header. Specific requests-per-minute and daily quotas are not published in the public documentation and vary by environment (test vs live) and account agreement; they are not reconciled in this artifact.

Mono Co Rate Limits is the machine-readable rate-limit profile for Mono on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring requests.

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 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Open Banking, Financial Data, Payments, Direct Debit, and Africa.

Per-Application Throttling
Limits are applied against the secret app key; separate keys for test and live environments.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on HTTP 429.
