Shares a payout wallet with 178 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Decide whether two Avro schemas are compatible, in both directions, under the resolution rules rather than by structural comparison. Backward is a reader on the new schema reading data already written with the old one; forward is a reader still on the old schema reading data written with the new one. Fields match by name with reader aliases consulted, int promotes to long, float and double one way only, and an enum symbol the reader lacks needs an enum default.

This payout wallet is shared: figures cover all 179 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator

On-chain agent identity and the x402 endpoint that shares its settlement wallet.
