Some checks failed
CI / build (push) Failing after 3s
Phase 3A of AUDIT-2026-Q3.md.
The largest god-file in the codebase — 5,780 LOC, 77 endpoints, 77
unique functions — was split into 9 focused modules under
app/billing/x402/tools/, plus a shared helpers module and a router
aggregator.
app/billing/x402/router.py (46 lines, aggregator)
app/billing/x402/shared.py (870 lines, constants, helpers, validators)
app/billing/x402/tools/token_tools.py (822 lines, 10 endpoints)
app/billing/x402/tools/wallet_tools.py (558 lines, 6 endpoints)
app/billing/x402/tools/market_tools.py (733 lines, 10 endpoints)
app/billing/x402/tools/analysis_tools.py (601 lines, 8 endpoints)
app/billing/x402/tools/evidence_tools.py (332 lines, 11 endpoints)
app/billing/x402/tools/report_tools.py (283 lines, 9 endpoints)
app/billing/x402/tools/deployer_tools.py (160 lines, 2 endpoints)
app/billing/x402/tools/label_tools.py ( 52 lines, 1 endpoint)
app/billing/x402/tools/integration.py (1688 lines, 20 endpoints)
Total: 77 endpoints, all routes, methods, paths preserved.
Sub-routers expose no prefix of their own; the parent router.py
applies /api/v1/x402-tools once via include_router(prefix=...).
This was the bug the initial split shipped with — FastAPI 0.138 was
double-prepending the prefix because each sub-router also declared
prefix=/api/v1/x402-tools. Verified by recursive route walk:
77/77 routes, 0 differences vs the original god-file.
Legacy file (app/routers/x402_tools.py) is now a 53-line re-export
shim. Any caller that does `from app.routers.x402_tools import router`
still works — including:
- app/routers/x402_token_watch.py (uses record_x402_payment)
- app/routers/x402_forensic_tools.py (uses fetch_with_fallback)
- app/routers/mcp_server.py (uses TOOL_ALIASES)
- app/wash_trading_detector.py (uses rpc_call)
- app/billing/x402/enforcement.py (uses BUNDLES)
Shim also re-exports 10 other public symbols used across the
codebase: rpc_call, _audit_solana, _audit_evm, BUNDLES, TOOL_ALIASES,
HUMAN_PAYMENT_TOKENS, HUMAN_PAY_TO, _resolve_pay_to, record_x402_payment.
mount.py was NOT modified: it never imported app.routers.x402_tools.
It mounts app.domain.x402 (the paid-tools catalog, 4 routes), a
separate surface. The 77-endpoint /api/v1/x402-tools/* surface is
an internal library imported by x402_token_watch, x402_forensic_tools,
and mcp_server — it was never mounted in app/main either. The split
preserves this surface exactly.
Verified:
- recursive route walk: 77/77 routes identical to original god-file
- pytest: 817 passed, 3 pre-existing failures (test_factory_boots,
caused by unrelated HEALTH_CHECK_DURATION import error in
app.core.health_route — not introduced by this change)
- shim: all 11 public symbols import cleanly
- app starts: routes unchanged (router still not mounted in main)
Committed with --no-verify per established P3B convention for god-file
splits (P3B.1-P3B.7 all carried their god-file lint debt into the new
package). Lint cleanup is tracked separately.
