Pulse Verity Index

Name: Pulse Verity Index
Author: pulse

Signed, verifiable crypto index prices for developers, AI agents and bots. Five read-only tools for current prices, batch reads, asset discovery, recorded settlement prints and ECDSA signature verification. Try BTC, ETH and SOL without an API key using the public pulse-verity npm package. This hosted MCP connection requires a Pulse developer sign-in or API key. A free key unlocks the catalogue, batch reads and settlement prints, subject to usage limits. Coverage and freshness vary by asset. Get started: https://thepulse.markets/developers?ref=smithery

能力清单

工具	说明
get_index_price	Get a current signed crypto index price from /api/index/v1/price. Returns symbol, price, optional priceText, at, grade, signature, kid and sig. Preserve priceText exactly for verify_print. Optional tier, confidence, dispersionBps, interval, sources, engine and cadence describe the observation but are not covered by the v1 signature. Coverage changes: use list_index_assets to discover assets. A stale or unavailable response means no current price, never zero.
get_index_batch	Read up to 100 crypto symbols in one /api/index/v1/batch request. Returns observations with individually signed successful rows and per-symbol errors for unavailable rows. Your API tier may allow fewer symbols. Verify each successful row with verify_print; surrounding batch and quality metadata are not signed. No automatic retries.
list_index_assets	Read one bounded page from /api/index/v1/verity/catalog. Discover crypto symbols and their current coverage status and measured cadence. Catalog rows, prices and metadata are unsigned: use get_index_price or get_index_batch for signed receipts. Availability changes; total is a catalog count, not a count of fresh prices. No automatic pagination.
get_settlement_print	Get the recorded signed index print nearest a requested time from /api/index/v1/print. Accepts ISO-8601 or epoch milliseconds. Check deltaMs: it is the distance between your requested time and the sampled print. Sampling and retention are bounded; a recorded print need not equal a separate live read. Preserve priceText and kid when present for verify_print. deltaMs and other metadata are not signed.
verify_print	Verify a signed print locally with ECDSA P-256/SHA-256. Canonical bytes are pulse-index-v1\n<symbol>\n<priceText or String(price)>\n<at>\n<grade>. The public key ring is read from /api/index/v1/pubkey, cached for five minutes and refreshed at most once per 30 seconds on a failed check. A supplied kid selects only that exact key; old prints without kid are tried against the bounded published ring. valid=true authenticates only the canonical price fields, not kid, sig, quality, cadence, timestamps outside at, or other metadata. An invalid signature can mean an altered print or a key no longer published; it does not by itself prove tampering.
