The Stall

210 pay-per-call AI data tools — no subscriptions, no API keys. Pay with crypto (x402/USDC on Base) or card (Stripe prepaid credits).

Live endpoint: https://the-stall.intuitek.ai MCP endpoint: /mcp — streamable HTTP, use POST Agent card: /.well-known/agent.json x402 discovery: /.well-known/x402 Catalog: /catalog MCP registry: ai.intuitek.the-stall/the-stall

Payment options

Two rails, same capabilities, no accounts required:

Option A — Crypto (x402, agents and wallets): Call any /cap/<name> endpoint → receive 402 Payment Required with the USDC price → pay on Base mainnet via the x402 facilitator → result returned automatically. No signup.

Option B — Card (Stripe, humans and devs): Buy prepaid credits once, then call any cap with Authorization: Bearer <token> — 1 credit per call, no gas, no per-call signing.

1. POST https://the-stall.intuitek.ai/v1/fiat/checkout with {"bundle":"starter"} → returns a Stripe checkout URL.
   • starter $5 / 100 credits · pro $30 / 1,000 credits · scale $200 / 10,000 credits
2. After paying: GET https://the-stall.intuitek.ai/v1/fiat/token?session_id=<id> → returns your bearer token.
3. Add Authorization: Bearer <token> to any /cap/<name> call.

Current capabilities — 210 live tools (v4.64.0)

Full catalog at /catalog. Each capability supports both payment rails — x402 (USDC on Base) and card/Bearer. No API keys, no accounts, no monthly fees.

Quick call (x402 flow)

# 1. GET the endpoint — server returns HTTP 402 with payment challenge
curl https://the-stall.intuitek.ai/cap/us-stock-price?ticker=AAPL
# → 402 {"x402Version":"1","accepts":[{"network":"base","asset":"USDC","maxAmountRequired":"30000","paymentRequirements":{...}}]}

# 2. Pay in USDC on Base via the x402 facilitator
# 3. Retry the request with the X-PAYMENT header — server returns data

See the x402 protocol spec for client SDKs (TypeScript, Python) that handle steps 2-3 automatically.

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:

[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:

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.

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.

Layout

the-stall/
  RUN_ME.sh                  self-documenting setup + boot
  src/
    server.js                the chassis: loads caps, paywalls them, serves free /catalog
    payment.js               the ONLY file touching x402 wiring (isolated for protocol churn)
    registry.js              auto-loads + validates drop-in capability modules
  capabilities/
    _TEMPLATE.js             the contract: copy → fill → it goes live next deploy
    ping.js                  liveness probe
    us-stock-price.js        US equity price + intraday metrics (Yahoo Finance)
    defi-portfolio.js        multi-chain wallet scanner (ETH/Base/Polygon/Arb)
    ... 206 more capability modules (see /catalog)

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)

1. Wallet ownership. WALLET_ADDRESS must be a verified-owned Base address.
2. 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.
