Live endpoints by network

base: 114 · solana: 10

Full data & real-time history (paid, x402)

GET https://moneytools.dev/index/v1/full — every probed endpoint with latest status, price, network, latency, uptime; filters liveOnly=1, network=base, host=, limit (≤5000). $0.005 USDC per call.
GET https://moneytools.dev/index/v1/lookup?url=<endpoint> — one endpoint's last 30 probes and next scheduled probe. $0.001 USDC. Not charged if the URL is not indexed (404).

Payment: x402 v2, USDC on Base (eip155:8453), payTo 0x64eB63904Cf9688AC5B3087A72AcF9C31a273169, facilitator PayAI. Call without a payment header to get the HTTP 402 terms. Before paying any third-party endpoint listed here, pre-check it with x402 Pay-Precheck (free demo) — or find one for your task with x402 Recommend.

Methodology & MoneyToolsIndexBot

notUsed: x402scan (its data API is itself paid via x402; we never pay endpoints or data sources)
probe: Unpaid HTTP GET (or POST with body {} when the catalog says POST), no payment header, max 2 redirects, 7s timeout. Live = HTTP 402 with parseable, well-formed x402 payment terms (verdict ok or warn) and payTo not on the OFAC SDN crypto-address snapshot.
schedule: Cron every 10 min: one catalog page (50 items) + up to 10 probes, max 1 probe per host per run; each endpoint re-probed at most every 6h when live, backing off to 12h/24h/48h when not.
politeness: User-Agent: MoneyToolsIndexBot (+https://moneytools.dev/index/). robots.txt is honoured (group MoneyToolsIndexBot, else *). Opt out: Disallow in robots.txt or email support@moneytools.dev.
caveats: Liveness only: a valid 402 does not mean the paid response works or is worth the price. Catalog entries are capped at 25 per host and 4000 total. MoneyTools' own services are excluded. Listing is not endorsement. Not financial advice.
