Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/paraswap: open an issue to ask a question, or submit a pull request to add artifacts.

  description: The Velora Delta API is an intent-based protocol that enables gas-less token swaps where multiple agents compete
    to execute trades on behalf of users. Users sign a Delta Order (EIP-712 off-chain signature) rather than making transactions
    themselves, which provides MEV protection through the Portikus Intents network. Currently supports Ethereum and Base networks.
