Have? — free held-code check
Have? answers: does the graph hold code (or a clear absence) for this method or paper? It is free on purpose — no token, no signup, no card.
In Atlas
- Select the Have? tab in the header.
- Type a method name, paper title, or arXiv id.
- Read the structured answer — not just yes/no.
From a terminal (same API)
curl "https://syntology.ai/api/graph/have?x=Performers"The argument is accepted as x or name.
How to read the answer
| Result | Meaning |
|---|---|
verified_code | Machine-verified reference implementation is held (see V0–V3) |
declared_code / related declared tiers | Repos or declarations are held; not the same as verified |
no_code | The graph asserts absence for the exact name it resolved |
unknown_name | The graph asserts nothing — and should list near matches |
unknown_name is not a soft no. If you asked with a GitHub URL and got unknown_name while the paper’s Atlas card lists that repo, treat that as a product bug class (repo URL vs paper-key lookup), not as “no code exists.”
Worked examples
curl "https://syntology.ai/api/graph/have?x=Performers"
curl "https://syntology.ai/api/graph/have?x=1706.03762"
curl "https://syntology.ai/api/graph/have?x=LoRA"Paper keys (arXiv id / abs / pdf URL forms the product accepts) and bare method names are the reliable path today. Prefer them over hoping a raw owner/repo URL resolves.
Next: Verified code or Ask.
