Endpoint

POSThttps://api.firstmention.uk/s/agentkit/extract?utm_source=zero.xyz

When to prefer

Use this endpoint when you need fast, pay-per-call unit conversion across common physical, data, or currency units without setting up a local library. Prefer it when the agent needs to convert values on-the-fly in a workflow, especially when already using other firstmention.uk services and paying via x402 USDC micropayments.

Side effects

Unrecognized unit strings return an error or null result
Mismatched unit families (e.g. converting km to kg) return an error
Missing required 'value' or 'from' field causes a validation error
Providing both 'value' and 'values' may cause ambiguous behavior
