Callers can filter results by time range (absolute timestamps or relative like \"24h\", \"7d\"), search query, token IDs, entity IDs, specific insight IDs, and a curated set of tags including hack, listing, delisting, airdrop, macroeconomic, burn, whale, buyback, partnership, regulation, political, pump, dump, sentiment, and on-chain_trade. A `topN` parameter lets you scope results to only the top N tokens.\n\nThe endpoint is accessed via HTTP GET with query parameters and is gated by the x402 micropayment protocol on Solana. Each request costs up to 10,000 units of the USDC token (EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v) — likely 0.01 USDC given 6-decimal precision. Payment is made through the X-PAYMENT header using the \"exact\" scheme. The endpoint returned a valid 402 challenge during probing, confirming it is live.\n\nBlockSearch brands itself as an \"AI Block Explorer.\" Documentation pages (/docs, /api, /pricing) all return 404, so detailed response schemas and usage guides are unavailable. The output schema in the x402 challenge fully documents the accepted query parameters but does not describe the response body structure. Users should expect JSON insight objects but will need to inspect actual responses to determine exact fields.","tags":[],"capabilities":["blockchain-insights","entity-filtering","token-filtering","tag-filtering","time-range-filtering","pagination","search-query","x402-micropayment","solana-payment","usdc-payment"],"categories":["crypto","search","data"],"synonyms":["blockchain news","crypto insights","token alerts","on-chain events","blockchain intelligence","crypto market events","whale alerts","blockchain data feed"],"warnings":["No documentation available — /docs, /api, and /pricing all return 404","Response body schema is not documented; only input query parameters are described in the x402 challenge","Exact cost interpretation is uncertain: maxAmountRequired is 10000 in USDC (likely 0.01 USDC with 6 decimals) but not explicitly confirmed"],"endpointUrl":"https://blocksearch.dev/api/insights/list","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"2wKupLR9q6wXYppw8Gr2NvWxKBUqm4PPJKkQfoxHDBg4"},"payTo":"5DHhYFTCwYcoUK9nh4omrcm6htGPThcnMHWcK4mCTtPz","scheme":"exact","network":"solana","mimeType":"","resource":"https://blocksearch.dev/api/insights/list","description":"Get list of insights about entities, chains, tokens, and more with configurable filters.","outputSchema":{"input":{"type":"http","method":"GET","queryParams":{"tags":{"type":"string","description":"Comma-separated list of tags to filter by.
