Endpoint

Choose this endpoint when you need a lightweight, pay-per-call URL extraction service that charges a fraction of a cent per request. Ideal for pipelines where you need to parse URLs from arbitrary text at scale without maintaining your own regex infrastructure. Best suited for single-text inputs rather than batch document processing.
Side effects
- Empty input string returns empty URL list or an error
- Malformed or non-standard URLs may not be detected
- Very large text bodies may time out or exceed input limits
- No URLs present in input returns an empty result set
- Input that is not a string may fail schema validation
