According to the listing title, it covers mint activity, whale tracking, floor price data, and wash trading detection. The endpoint path (`/x402/bitquery/nftanalytics/raw`) suggests it returns raw Bitquery query results for NFT-related on-chain data.\n\nAgent Einstein is a broader AI agent platform that supports x402 payment protocol, A2A, and MCP integrations. The platform accepts payments in USDC on Base, USDC on Solana, and BTC via Lightning Network. Paid features on the platform typically cost $0.20–$1.00 per invocation, with discounts up to 60% for E=MC² token holders. Users can also bypass payments by providing personal API keys (including Bitquery keys) or being on the wallet whitelist.\n\nHowever, at the time of probing, the endpoint returned HTTP 502 on both GET and POST requests, and the origin server also returned a 502 (Cloudflare Error 522 — origin timeout). This means the endpoint is currently unreachable and cannot be confirmed as live. The `/api` path also showed a Cloudflare 522 error, indicating a broader origin server outage. No x402 payment challenge was captured, so pricing details specific to this endpoint are unavailable.","tags":[],"capabilities":["nft-analytics","mint-tracking","whale-monitoring","floor-price-data","wash-trading-detection","bitquery-integration","x402-payment"],"categories":["crypto","nft","analytics"],"synonyms":["NFT analysis","NFT whale tracker","NFT floor price","wash trade detection","NFT mint analytics","Bitquery NFT","on-chain NFT data","NFT collection stats"],"warnings":["Endpoint returned HTTP 502 on both GET and POST — origin server appears down (Cloudflare Error 522).","No x402 payment challenge was captured; endpoint liveness cannot be confirmed.","No OpenAPI or endpoint-specific schema available; request/response formats are inferred from the endpoint name only.","The /api path also returned a 522 error, suggesting a broader origin outage.","Example request JSON is speculative — no schema documentation was found for this endpoint."],"endpointUrl":"https://emc2ai.io/x402/bitquery/nftanalytics/raw","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xc9368b30BD620164FD1a05a5d99dcaf8Ae754775","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://emc2ai.io/x402/bitquery/nftanalytics/raw","description":"NFT collection analysis: mints, whales, floor prices, wash trading detection.","discoverable":true,"outputSchema":{"input":{"type":"http","method":"POST","bodyType":"json","bodyFields":{"chain":{"enum":["base","ethereum","bsc","arbitrum","polygon","optimism","solana"],"type":"string","description":"Blockchain to query (e.g., base, ethereum, bsc, solana)"},"limit":{"type":"string","description":"Maximum number of results to return (default: 10, max: 500)"},"timeperiod":{"enum":["1h","4h","24h","7d","30d"],"type":"string","description":"Time period for analysis (e.g., 1h, 24h, 7d, 30d)"}},"discoverable":true},"output":{"result":{"type":"object","description":"Query result data"},"status":{"type":"string","description":"Request status (completed or error)"},"payment":{"type":"object","description":"Payment receipt information"}}},"maxAmountRequired":"1000000","maxTimeoutSeconds":90}]},"qualityScore":"0.150","qualityRationale":"The endpoint returned 502 on all probe attempts and the origin server is experiencing a Cloudflare 522 timeout, indicating the host is down.
