How this service works
Convert fresh, active dry and instant yeast, split a sourdough starter into flour and water, or plan a starter feed.
Output
Returns a JSON object with the computed result in grams (resultG), the input amount (amountG), the source and target yeast types or mode, a human-readable summary, relative strength figures comparing yeast types, and a disclaimer noting any caveats. For starter and feed modes, it breaks out flour and water components and explains the calculation.
Example use cases
Yeast type substitution for bread recipe
“My pizza dough recipe needs 10g of instant yeast but I only have fresh yeast — how many grams of fresh yeast should I use?”
Sourdough starter flour and water split
“I have 250g of sourdough starter at 80% hydration — can you tell me how many grams of that are flour and how many are water?”
Sourdough starter feeding plan
“I want to feed my sourdough starter up to 300g total using a 1:2:2 ratio at 100% hydration — how much flour and water do I need to add?”
Technical details
Endpoint
GEThttps://cooking-calc.x402tookit.com/yeast-sourdough?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs precise, authoritative gram-based yeast conversions or sourdough starter math rather than relying on approximate rules of thumb. It is the right choice specifically for yeast-type substitutions (fresh/active-dry/instant), starter hydration breakdowns, and feed planning with ratio control — all in a single call with a structured, parseable response.
Side effects
- Missing required 'mode' query parameter returns an error
- Invalid mode value (not 'yeast', 'starter', or 'feed') causes rejection
- Invalid yeast type for 'from' or 'to' (not fresh/active-dry/instant) causes error
- Missing 'amountG' in yeast mode or 'starterG' in starter mode causes incomplete response
- Malformed ratio string in feed mode (e.g. non-numeric parts) may cause calculation failure
- Payment failure results in 402 response before computation
