XRP Fleet Data — metered XRPL reads you pay for in XRP

A pay-per-request data rail for agents. Standard x402 v2 flow: we answer 402 Payment Required with a challenge, your wallet signs an XRPL Payment locally, we verify and serve. No signup, no key, nothing to prefund. Payments are non-custodial both directions: destination and amount are frozen inside the blob you signed, and each challenge is bound to a single-use invoice.

Start here — free liveness probe (no payment)

curl -s https://d5e7fd5a.xrplclaw.com/app/nodes/api/v1/feed/latest

Returns the latest consensus-checked fleet snapshot: metrics.ledger_index, med_fee_drops, queued_txn_count, plus age_s. Read these flags before trusting anything:

• stale: true / ok: false / tier: "FREE-LEADGEN-STALE" → the consensus bridge stopped feeding (older than ~300 s). Show the last sample but do not present it as live.
• metrics.close_time_iso: null is normal; use ledger_index deltas for liveness.

Also free: /api/status (server info + books), /api/earnings (aggregate revenue totals only), /api/v1/feed/stats is paid.

Paid paths (drops, 1 XRP = 1,000,000 drops)

Path	Drops	Returns
GET /api/v1/feed/history?n=..	200	up to 1440 historical snapshots (~90 s cadence)
GET /api/v1/feed/stats	100	row count, span, ok-rate of the consensed feed
GET /api/v1/ledger?index=validated	100	ledger object (proxied read)
GET /api/v1/account/{r-address}/info	100	account root: balance, sequence, flags

Prices never exceed 200 drops/request today. Confirm live prices before wiring them permanently.

Pay with x402 v2 — use the bundled fail-closed client

This skill ships scripts/guarded-buy.cjs, a fail-closed client whose money path is linear and self-auditing — nothing is signed from a challenge that was not inspected, the bytes about to be signed are re-checked against that inspection, and the seller's receipt must name the tx we signed:

1. GET the resource → read accepts[0]; sign nothing yet
2. gate the challenge → host allowlist, xrpl:0, scheme exact, pinned payTo, MAX_DROPS price cap, persisted daily budget, mandatory single-use invoiceId, advertised sourceTag, bounded horizon
3. presign a Payment built from that object only (same amount, destination, source tag, invoice memo)
4. gate the pre-sign bytes → TransactionType=Payment, Account=signer, Destination=payTo, Amount=gated drops, SourceTag match, invoice memo present, LastLedgerSequence set
5. retry once with PAYMENT-SIGNATURE, decode PAYMENT-RESPONSE, and warn loudly if the receipt tx hash differs from our own signature hash
6. write actual drops into a local per-UTC-day ledger so cumulative spend can never drift past budget

npm i x402-xrpl@0.2.0 xrpl        # in the directory you run from
XRPL_SEED=... node scripts/guarded-buy.cjs /api/v1/feed/stats /api/v1/ledger
NO_PAY=1 XRPL_SEED=... node scripts/guarded-buy.cjs /api/v1/feed/stats   # gate + price only, signs nothing
node scripts/guarded-buy.cjs --selftest                                  # offline proof of every gate

Env knobs (fail-closed defaults): MAX_DROPS (200 = this rail's ceiling), DAILY_BUDGET_DROPS (50000), EXPECT_PAYTO (published payee), EXPECT_HOST, EXPECT_SOURCE_TAG (804681468), MAX_TIMEOUT_SECONDS (300), WS_URL (wss://rpc.xrplclaw.com/ws, used only to fetch fee/sequence — the client never submits), BASE_URL, ALLOW_SPEND_FILE, NO_PAY=1. Output is one JSON line per purchase: {url, paid, drops, tx, ours, settlement, data} — ours is the hash we signed; reconcile tx against your own wallet delta, never against our word.

Use a dedicated low-balance hot wallet. Never your main or a custodial wallet; never paste a seed into chat, a prompt, a file in a repo, or this skill's arguments.

Prefer this client over wiring x402Fetch by hand. A stock wrapped-fetch pays whatever challenge it receives on its own retry round trip — so any cap you enforce on a probe response you read separately can be a different invoice than the one actually signed. If you do use the library directly, pass a paymentRequirementsSelector (and/or your own fetchImpl) so validation runs against the exact accepted object being paid, and pin schemeFilter/network:

import { x402Fetch } from 'x402-xrpl';
import { Wallet } from 'xrpl';
const payWith = x402Fetch({
  wallet: Wallet.fromSeed(process.env.XRPL_SEED), network: 'xrpl:0', schemeFilter: 'exact',
  maxValue: 200_000,                                   // library-level ceiling, drops
  paymentRequirementsSelector: (accepts, net, scheme, max) => {
    const a = accepts.find((x) => x && x.payTo === EXPECT_PAYTO && Number(x.amount) <= 200);
    if (!a) throw new Error('refusing unapproved challenge');
    return a;
  },
});

Python: pip install x402_xrpl==0.2.0, then x402_requests(wallet, rpc_url, network_filter="xrpl:0", scheme_filter="exact").

Challenge fields advertised by this server: scheme=exact, asset=XRP, network=xrpl:0, sourceTag=804681468, maxTimeoutSeconds=120, single-use extra.invoiceId (memo hex or InvoiceID=sha256). Stock clients read accepts[] from the 402 body — if you hand- roll a client, parse the body, not only headers.

Receipt semantics:

• PAYMENT-RESPONSE header, decoded success:true + transaction → already on-chain.
• X-Payment-Settlement: pending → served now; the payment is confirmed within seconds and shows up in /api/earnings. If the hosted facilitator stalls, the seller rebroadcasts your signed payment through its own trusted endpoint rather than letting your money sit — you are charged once either way.

Spend guardrails (the client above enforces all of these)

An auto-paying client signs whatever a challenge asks. Before pointing one at anything:

1. Cap per-request drops (this rail's ceiling is 200) and set a daily budget with a hard stop.
2. Allowlist the host and pin the expected payTo address — only pay challenges you chose.
3. Persist cumulative spend (the bundled client writes .xrp-fleet-data-spend.json) and refuse past it.
4. Log every tx hash you signed; reconcile against your wallet's account_info delta, not our word.
5. Stop and report if the charged delta ≠ advertised price. Any surprise should look like a network fee (~10–12 drops), never a bigger payment.

Flat-rate plans (optional, cheaper at volume)

• hobby — 10,000 drops (0.01 XRP) / 30 days, 10 req/min
• pro — 7,000,000 drops (7 XRP) / 30 days, 120 req/min

Buy once through the same x402 flow (GET /api/v1/subscribe/hobby|pro), then add an X-Sub-Auth: <pubkey-hex>|<der-sig-hex>|<unix_s>|<nonce> header on later calls (secp256k1 key of the paying address; ±180 s tolerance, single-use nonce). Grants are bound to the payer address, renewals stack, over-cap returns 429, and a bad/expired token silently falls back to pay-per-call. Full spec: site/nodes/API.md §Flat-rate plans. For very high frequency there is also a zero-fee XRPL PaymentChannel lane (X-XRP-Payment) — see /api/v1/pricing → payload_spec.

Honest limits of this rail

• Origin is a consensed Evernode/HotPocket instance on a community host; the bridge samples every ~90 s. It is not a low-latency mempool feed.
• /api/status reports flag: "OBSERVED": network facts (validated seq, ledger age, load_factor, complete_ledgers, reserves) come live from XRPL mainnet CLIO (public-reference), and median fee + queued-txn count are measured in-consensus by the Evernode instance. Host cpu/mem/disk/peers are null with host_metrics.available: false until a VPS exposes a rippled admin interface — nothing is synthesized here. Legacy /api/metrics/history rows (pre-2026-10-01T22:58Z) carry demo node_cpu values and are self-labeled in that response's provenance block.
• Proxied reads share one upstream: bursts can be rate-limited; availability is best-effort, no SLA.
• No full-history archive queries yet.
