Architecture

A domain-agnostic x402 capability chassis + a proprietary intelligence layer that decides what capability to put in it. Built as the answer to one question: where is the way into the agentic economy that a solo operator can actually take, given that the giants now own the rail?

The architecture decision

The giants (Coinbase, Stripe, AWS, Visa, the x402 Foundation) own the rail — settlement, wallets, the discovery index. That seat is taken; don't fight for it. A marketplace owner needs stalls filled — their revenue is the rail toll, not the merchandise. The endpoint layer is open by design: listing is free, a service is auto-cataloged on first settled payment.

So this splits into two parts:

	The Stall	Intelligence Layer
is	infra — a reusable paid endpoint	proprietary signal analysis
owns	x402 wiring, payment, schemas	the doctrine + the archive
changes	almost never	every scan cycle
answers	"how does an agent pay me"	"what will an agent pay me for, where the seat is open"

[REDACTED]4 — what the [REDACTED] does

v0.4 retires catalog scanning as the primary scout (v0.1/v0.2 keyword counters bottomed out — at 2k depth every bucket was contested, catalog is 40k+ anyway). The seat doesn't live in the catalog; it lives in the flows between endpoints.

Five streams write into a SQLite archive (archive.db), four analyses read it:

Stream	Auth	What it gives
`bazaar`	none	every Bazaar endpoint with first-seen/last-seen → new-endpoint feed
`base_rpc`	none	live x402 settlements from Base mainnet via public RPC — payer/recipient/amount per EIP-3009 event
`cloudflare`	`CF_API_TOKEN`	AI-bot traffic share by user-agent and AS → school identity
`dune`	`DUNE_API_KEY` + query IDs	SQL-side aggregation convenience over the same on-chain data (optional)
`x402scan`	`X402SCAN_API_URL`	settlement feed if x402scan publishes a public API (placeholder; none as of 2026-05)

base_rpc removes the auth wall for settlement-level signal. Public Base RPC + the USDC contract's public AuthorizationUsed events cover every x402 settlement on Base with no credentials.

Analysis	Hook	v0.4 status
`growth`	category emergence — list adjacent under convergence price	partial without history
`seam`	collapse a 2-3-endpoint chain, price at 70% of summed	unlocked by `base_rpc`
`convergence`	ship the narrow version agents converged on	unlocked by accruing `base_rpc` over time
`concentration`	better latency/price/schema, surfaced to the dependent cluster	(a) few-payers: unlocked; (b) cluster-dominant: gated

First end-to-end run with base_rpc: 1,222 real settlements pulled in 2.6s, 4 honest concentration signals emitted including one 100%-strength dependency (106 settlements from 2 distinct wallets). All from public data, no auth.

The archive thesis (the second timeline)

The same archive.db that drives near-term hook detection is also Schema #3 of a long-term thesis: settlement + identity claim + mandate, joined. Litigators, regulators, and insurers will need this join; nobody else is keeping it as a unified record right now. One build, two timelines.

Quickstart (self-hosted)

./RUN_ME.sh           # installs, scaffolds .env, optionally boots on testnet
npm run scan          # intelligence scanner: pulls streams, runs analyses, prints seat report
npm start             # boot the stall (base-sepolia by default = $0 risk)
curl localhost:4021/catalog

Stream 3 (Bazaar) runs every scout cycle with no setup. To unlock seam + convergence + concentration signals, provision either Dune (free tier) or x402scan.

Two gates before live USDC (if self-hosting)

Wallet ownership. WALLET_ADDRESS must be a verified-owned Base address.
Source ToS / licensing. Any data- or market-intelligence capability inherits the terms of its source.

Deploy (Railway)

Standard Node service. Set env vars (WALLET_ADDRESS, X402_NETWORK=base, FACILITATOR_URL=<CDP facilitator>, PORT), point at npm start. Keep the archive.db volume persistent across deploys (it's the asset).

Migrating from orbisapi

Several orbisapi proxy endpoints went offline in June 2026. The Stall covers all of them at lower prices with no x402 configuration required beyond a Base USDC wallet:

All STALL capabilities are x402-compatible — the same payment flow, USDC on Base, no re-integration needed. Update pay_to address and endpoint URL.
