https://api.3route.io/v1/pro/:chainId/swap

Shares a payout wallet with 9 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Build an unsigned swap transaction for the best route. Compare it with a fresh quote, validate every returned transaction field, obtain signing approval, and broadcast it through the chain's RPC. The parameters permit and usePermit2 are ignored. An ERC-20 source must approve the router in tx.to for at least srcAmount first. Supports exact-output amounts, historical state for approximately 35 days, and multiple amounts at once; the first request for a block may take 1-7 seconds.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
0

How often it was reachable when we probed it (weight 35%).

Latency
not yet measured

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
42

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
8

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 30% — how much probe evidence backs this score. A thin history is flagged, not hidden.

See the scoring methodology for exactly how each number is computed.

This payout wallet is shared: figures cover all 10 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
