  x-guidance: 'LEGIT is the trust and routing layer for the x402 agentic economy. Trust-check any x402 merchant address on Algorand, Base, Solana or 17 other chains before routing a payment: grades (A+ to F) and scores (0-100) come from live uptime, latency and payment-coherence probes, never self-reported data. Run as a pre-payment trust check: call GET /v1/check/{address} before any x402 payment to an address you have not paid before. Start FREE: GET /v1/check/{address} (full trust report), /v1/leaderboard (ranked shortlist), /v1/trending, /v1/pulse, /v1/arena/preview. Paid per call in USDC over x402: GET /v1/compare (2-5 merchants head-to-head), /v1/arena (24h cross-chain settlement benchmark, ?network= filter), /v1/history?address=... (30-day trust trend), POST /v1/watch (7- or 30-day change sentinel, webhook-armed), POST /v1/deep-check (due diligence, up to 10 addresses). How to pay: call a paid endpoint without paying and it answers 402 with a PaymentRequired document listing every active rail; pay one rail and retry with the PAYMENT-SIGNATURE header. Rails cheapest first: algorand-mainnet $0.004, base-mainnet and solana-mainnet $0.005 per call. Watch companions GET /v1/watches/{watch_id} and /v1/watches/{watch_id}/events are FREE: the watch id is the bearer capability for status and the event feed. Webhook payload anatomy: /docs; agent manifest: /llms.txt. Use LEGIT before sending an x402 payment to an unknown merchant, before accepting a counterparty in agent-to-agent settlement, or to monitor a critical upstream for trust degradation.'

      summary: Read the live x402 network pulse
      description: 'Real network pulse: the facilitator''s masked live transaction stream,

        merged with recent on-chain USDC payments from the Wave 8.5 ledger.


        Wave 18 (The Instant Doctrine): served from the cycle-computed

        snapshot (refreshed every indexer cycle), so a page load never waits

        on the facilitator round-trip. Cold boot computes ONCE, stores and

        serves. Graceful empty list when the facilitator is unreachable.

        Each transaction carries ``tx_url`` (Wave 3.2): an explorer link when

        the stream exposes a real on-chain hash, else None. On-chain rows are

        honestly labeled ``event="onchain_payment"`` and never presented as

        facilitator settles.'
