Teams from across Google, including Ads teams, are actively engaged in industry dialog about new technologies that can ensure a healthy ecosystem and preserve core business models. Online discussions (e.g. on GitHub) of technology proposals should not be interpreted as commitments about Google ads products.

This code provides a server that can run JavaScript bidding and ad scoring functions, as specified in the FLEDGE explainer. The idea is to experiment with moving evaluation of JS from on-device to a server instead.

Discussions of how to add trust to the server are not covered here, see.

Bidding functions are currently statically configured in a server/sample_configuration.yaml file that gets built into the container. Edit the file to add or change the bidding function that Aviary should be able to run, for example:

biddingFunctions:
  squaring: |
    (function(inputs) { return inputs.perBuyerSignals.contextualCpm * return inputs.perBuyerSignals.contextualCpm; })

bazelisk run //server:aviary

bazel run //server:aviary

export PORT=8080; docker run -p ${PORT}:${PORT} -e PORT=${PORT} bazel/server:aviary

curl -X POST http://localhost:8080/v1alpha/adAuctions:computeBid -d '{"biddingFunctionName": "doubling","input": {"perBuyerSignals": {"contextualCpm": 1.23}}}' -H "Content-type: application/json"

 "bid": 2.46
