  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: Run deep-check due diligence on up to 10 addresses
      description: 'Bulk due diligence for up to 10 x402 merchants in one call.


        Every tracked address returns the full trust snapshot with the

        complete parsed score breakdown, a compact 30-day history (daily

        uptime, average score and modal grade), its rank percentile within

        its own network, first/last seen timestamps and its probe tier.

        Untracked addresses are listed honestly under "untracked"; nothing is

        silently dropped and nothing is invented. Tracked merchants stale for

        their probe tier queue an on-demand re-probe each.


        Wave 40 (La Voce, W5): Base merchants with at least one real USDC

        settle found by LEGIT''s independent eth_getLogs chain scan over the

        last 7 days carry an additive "evidence" block

        ({"base_usdc_settles_7d": n, "evidence_source":

        "independent_chain_scan"}). It is omitted for everyone else: absence

        of proof is not proof of absence. Metadata only, never a scoring

        input; a scan failure omits the field, never an error. Paid: $0.004 on Algorand / $0.005 on Base, via x402 (per call in USDC on algorand-mainnet or base-mainnet; the 402 response lists every active rail). The POST /v1/watch 7-day diagnostic tier pays the same per-call rail price as the 30-day watch.'
