AskRegistry

Source: src/AskRegistry.sol. Solidity 0.8.30.

The price book. Providers publish signed quote snapshots; any key can relay them. There is no curation surface; the provider signature is the only authority. No contract reads the book: prices reach a job only through the client-signed Order.

Skip rulesCopy Anchor Link

Each entry of setAsks is checked in this order and skipped at the first failure:

1. quotes.length > MAX_QUOTES (64)
2. signedAt > block.timestamp + 3600
3. The recovered signer is address(0) (malformed signature)
4. idOf(signer) == 0, or idOf(signer) != snapshot.providerId
5. signedAt <= lastSignedAt[providerId]

A skipped entry writes and emits nothing, so the reason is not visible on chain. Confirm a publish by reading lastSignedAt or the AsksPublished log.

SemanticsCopy Anchor Link

• Storage is an upsert keyed by (providerId, modelId, sla): a snapshot writes only the slots it lists. To withdraw a quote, publish it with rateIn == 0 && rateOut == 0.
• A quote with only one nonzero rate is valid, for example an input-metered model with rateOut == 0.
• AsksPublished carries the whole snapshot. An empty quotes array is valid: it advances the floor and emits an empty list, but clears no storage.
• One lastSignedAt floor per provider. An exact duplicate is skipped, so retries are safe.
• Only idOf is checked. Listing, capacity and model status are enforced at post and claim, not here.
• After an operator key rotation, snapshots signed by the old key are skipped, including replays of ones already published.

The canonical signature is AsksPublished(uint32,uint64,(uint32,uint32,uint128,uint128)[]).

struct Ask {
