mpp-pay from x402-doctor (#139): the agent sends USDC.e on Tempo with the MPP memo and answers with the transaction hash, checked on a Tempo RPC; the 402 then carries an evm and a tempo challenge and /openapi.json lists both offers. Off until MPP_TEMPO_RECIPIENT is set. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TsD5haPKxeWjYmErHzvU48

A 402 with a payment that was refused now logs network (from the x402 payment header, or the MPP credential's method: evm = base, tempo = Tempo), so the usage log can show which network traffic comes from.

On mainnet the paid routes also accept the same dollar price in RLUSD on the XRP Ledger, to XRPL_PAY_TO (default Frits's account with the RLUSD trust line; XRPL_PAY_TO=off turns it off), verified and submitted by an in-process facilitator from @x402/xrpl, as in the other Fizzl services. The usage log counts RLUSD in dollars. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TsD5haPKxeWjYmErHzvU48

Agents built on t54's x402-xrpl / Xrpl.X402 SDK (most of the XRPL AI Hub)
sign with the x402 SourceTag 804681468, bind the invoice in Memos and send
{ signedTxBlob, invoiceId }. @x402/xrpl refuses Memos, so those payments now
go to t54's hosted facilitator, which verified and settled such a payment
on testnet; standard @x402/xrpl payments stay in-process (also re-tested on
testnet with the SourceTag in the requirements). Every XRPL accept now
carries extra.sourceTag. XRPL_T54_URL=off keeps everything local.

A refused MPP credential is logged as payment_failed with protocol mpp; it now also carries reason (the problem detail sent back, max 160 characters), so a client that can't pay us shows what went wrong.

A refused MPP credential (payment_failed, protocol mpp) now also carries
reasonin the usage log: the problem detail sent back, at most 160 characters. The same change is in the other three services. Tests pass (27).🤖 Generated with Claude Code
