Collapses the eth-block → stablecoin-watch 2-hop chain. Block fields: number, hash, miner, timestamp, gas_used, tx_count. Stablecoin fields: symbol, price, peg_deviation, depeg_status, composite alert level. Supports Ethereum, Base, Polygon, Arbitrum. Free upstreams (DRPC + DeFiLlama), no API key required.","url":"https://the-stall.intuitek.ai/cap/chain-pulse","method":"GET","headers":{},"bodySchema":{"type":"object","properties":{"properties":{"type":"string"}}},"responseSchema":null,"example":{"request":{"properties":"chain_metrics"},"response":{"ts":"2026-06-12T05:10:32.509Z","block":{"hash":"0x04eee89bb0883f15f4cc913d81341f093dc08c688650719b9601bdfa5a687d24","miner":"0x4838b106fce9647bdf1e7877bf73ce8b0bad5f97","network":"ethereum","gas_used":13307451,"tx_count":103,"gas_limit":60000000,"block_number":25299207,"base_fee_gwei":0.1336,"timestamp_iso":"2026-06-12T05:10:23.000Z","timestamp_unix":1781241023},"stablecoins":{"coins":[{"price":0.998668,"symbol":"USDT","depeg_status":"MILD_DEPEG","peg_deviation":0.001332,"circulating_bn":186.63},{"price":0.999745,"symbol":"USDC","depeg_status":"PARITY","peg_deviation":0.000255,"circulating_bn":74.94},{"price":0.999531,"symbol":"USDS","depeg_status":"PARITY","peg_deviation":0.000469,"circulating_bn":8.39},{"price":0.999055,"symbol":"USDe","depeg_status":"PARITY","peg_deviation":0.000945,"circulating_bn":4.48},{"price":0.999662,"symbol":"DAI","depeg_status":"PARITY","peg_deviation":0.000338,"circulating_bn":4.43},{"price":0.998169,"symbol":"USD1","depeg_status":"MILD_DEPEG","peg_deviation":0.001831,"circulating_bn":4.34},{"price":1,"symbol":"BUIDL","depeg_status":"PARITY","peg_deviation":0,"circulating_bn":3.03},{"price":1.127787,"symbol":"USYC","depeg_status":"SEVERE_DEPEG","peg_deviation":0.127787,"circulating_bn":3.01},{"price":0.999614,"symbol":"PYUSD","depeg_status":"PARITY","peg_deviation":0.000386,"circulating_bn":2.74},{"price":0.999608,"symbol":"USDG","depeg_status":"PARITY","peg_deviation":0.000392,"circulating_bn":2.59}],"count":10,"alert_level":"RED"}}},"exampleRequest":{"properties":"chain_metrics"},"tags":["x402"],"displayCostAmount":"0.059","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"settled","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.059/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.117","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.117","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_YZwdz8KpmhAjKrG_7ed1u","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.117","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Returns real-time pulse/health metrics for blockchain networks, such as transaction throughput, block times, gas prices, or congestion signals.","exampleAgentPrompt":"Can you check the current pulse of the Base mainnet — I want to know how active the chain is right now, including things like block activity or congestion?","exampleUseCases":null,"resultDescription":"Returns a snapshot of blockchain network activity metrics for the requested chain, potentially including block throughput, transaction counts, fee levels, and overall network health signals — paid via USDC on Base mainnet at $0.006 per call, no API key needed.","failureModes":["Unsupported chain identifier returns an error or empty result","Malformed properties filter leads to a 400-level response","Network unavailability causes timeout or 5xx error","Payment failure (insufficient USDC or x402 handshake issue) blocks the request"],"whenToPreferThis":"Choose this endpoint when an agent needs a quick, keyless, pay-per-call snapshot of blockchain network health or activity without setting up accounts or subscriptions — especially useful for Base mainnet monitoring given the native USDC payment integration.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-13T12:50:06.896Z","isFirstParty":false}
