### HIGH PRIORITY: surface DELTA in OpenSea Tools / x402 Bazaar buyer layer

## Why this is high-value
OpenSea now exposes a public Agent Tools marketplace with x402-paid tools, human and agent invocation paths, MCP discovery, CLI/API search, and visible 7-day call/caller/volume metrics. This is not a passive directory.

Fresh adjacent-demand evidence checked 2026-09-06:
- `Payment guard` — 7 calls / 2 callers / $0.07 volume in 7d: https://opensea.io/tools/x402-bazaar/base/8483215557592508350
- `TxGuard - Tx preflight` — 25 calls / 1 caller / $0.25 volume in 7d:…

### HIGH PRIORITY: Register DELTA on Tollbooth / Hermes x402 buyer router

## Why this matters

### HIGH PRIORITY: PayAPI Market listing can generate receipt-backed external verification settlement

## Why this is high value
PayAPI Market is a live x402 marketplace whose verification badge is settlement-backed rather than self-attested. Public marketplace data checked 2026-09-05 shows **118 live APIs / 801 endpoints / 101 settlement-verified listings**. The site states that every verified third-party listing was paid from PayAPI Market's own buyer wallet and returned real product; 9 verified listings are first-party, so most verified records are third-party.

Discovery is exposed through:…

### HIGH PRIORITY: DELTA absent from full PayAI Bazaar scan; restore discovery path

## Evidence
Latest DELTA Discovery Pulse run `33874535058` (2026-09-04 12:47 UTC) completed a full PayAI Bazaar visibility scan across **28,113 resources** and returned:

```json
{"total":28113,"scanned":28113,"scan_complete":true,"matches":[]}
```

At the same time production DELTA was healthy (`/health` returned version `0.6.1`, Base `eip155:8453`) and `/v1/preflight` returned a valid unpaid HTTP 402 challenge. So this is not a basic uptime/paywall failure; DELTA is simply not present in that…

### HIGH PRIORITY: dual-stack DELTA x402 + MPP and register in live MPP marketplace

## Why this is evidence-backed
Agent402's MPP marketplace is not just a directory claim. It live-probes sellers for a genuine `WWW-Authenticate: Payment` challenge and publishes an on-chain leaderboard. Current public data shows 293 live-verified MPP sellers / 351 endpoints; Agent402's own buyer surface reports 3,558 outside-buyer settlements and 118 distinct buyers in 30 days, with host canary/volume excluded from those figures. Registration is free and programmatic.
