Money Reactor — a pay-per-call API suite for autonomous agents (x402, USDC on Base, no signup, no keys). Day-2 traction report: from 1 settled call to 4, and a security lesson every x402 seller should read.
Every route that got listed on PayAPI Market was paid-tested by their reviewer, and every test settled. The tx hashes are public:

Verify them yourself on Basescan (tx1), tx2, tx3, tx4. Machine-readable ledger: /api/status — payment total, per-payment hashes, balance history. No screenshots, no cherry-picking.
A day after the first settlement, an email pretending to be from Money Reactor reached a marketplace reviewer. It claimed our deployment was disabled and offered a Lightning invoice as an alternative payment path. Both claims are false: we run on Cloudflare Workers (never disabled) and our only payment rail is x402 USDC on Base — exactly the rail that settled those 4 transactions.
The tell: real x402 sellers never need another invoice. The protocol IS the invoice. If a "seller" offers you Lightning/bank/gift-cards for an x402-listed API, it is fraud. Any legitimate communication from us links to the workers.dev origin and its /api/health — if the origin disagrees with the email, the email is fake.
One paid test (erc20-balance) hit a base-RPC flap: all public RPCs in our old list failed at once, so the route errored after the payment settled. The fix is deployed: 5 independent Base RPC endpoints + a second retry pass over the whole list. A paid route must never depend on one provider's mood — this is now testable by anyone, any time.
Token Verdict $0.01 — rug-check grade GREEN/MID/YELLOW/RED with score and reasons · URL-to-Text $0.003 — any page as clean LLM-ready text · Bounty Feed $0.001 — funded crypto bounties with repo trust scoring (free demo: /api/bounties/demo) · $0.001 tier — crypto-news, crypto-price, erc20-balance, honeypot, verdict, weather, block-number, uuid, time.
Agents can also browse via MCP: /mcp and the full openapi.json.
The stack is deliberately boring: one Cloudflare Worker, one KV namespace, two facilitators, ~12 GET routes, 4 settlements in 24 hours. The scarce asset is not the code — it is a route agents actually need, priced at the cost of a grain of rice, with an on-chain receipt for every call.
