  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.'

      description: 'Wave 6 (The Arena): the public cross-chain x402 settlement benchmark.


        Ranks every chain with any signal (pulse transactions in the last 24h,

        tracked merchants, or facilitator network health) by real settle count

        (Wave 8.9: micropayments are a count economy; volume only breaks ties).

        Cached 60s. Honest by construction: with zero pulse data in the

        window the narrative says the arena is still gathering its first data

        and no leader is named. Wave 39 (Il Biglietto da Visita): the optional

        ?network= slug narrows the benchmark to one chain (cached separately

        per slug); an unknown slug is an honest 400 listing the valid slugs. 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.'
