Pulse Verity

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; they are not covered by the v1 signature, and the v2 block signs them with the price. Pass the whole prin

Read signed prices for up to 100 symbols per request; this account's plan may allow fewer (get_account_status reports batchMaxSymbols). One /api/index/v1/batch request returns observations with individually signed successful rows and per-symbol errors for unavailable rows. A request over the plan's limit is refused with code TOO_MANY_SYMBOLS: split it. Verify each successful row with verify_print;

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 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. qualityRecorded says whether its quality fields were stored when it was recorded (prints from 1 Oc

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.

Read this connection's Pulse Verity plan and usage from /api/index/v1/account: plan, used (calls counted this UTC month), limit, remaining, resetAt, perMinute, batchMaxSymbols, capacityAction and upgradeUrl (the plans page). The monthly allowance is account-wide: every key and connected app on the account shares it. perMinute applies to each key. This call does not count toward the allowance.

Read price history for one crypto symbol from /api/index/v1/history: candles (open, high, low, close) at 1m, 5m, 1h or 1d, with period metrics and pagination. dataset=verified (default) is built from prints Pulse signed live; reconstructed is rebuilt history at 1h or 1d and was not signed at the historical time. The account's plan sets whether history is included and how far back a request reaches

List the Pulse Verity plans with their limits and prices, and the prepaid call packs and extra stream connections while each is on sale, each with a portal link. Read-only; does not count toward the allowance. The current plan is marked when the account is on that plan's terms (currentPlan shows the account's own limits either way), and when a recent plan refusal is known (or reason is given) the

Write one structured bug, missing capability, or data quality report for private human triage. Only submit when the user requests reporting; do not include keys, passwords, transcripts or attachments. Returns a durable receipt and duplicate flag, not a promise of a fix. No code or production behavior changes automatically. Status is available with the same account at GET /api/index/v1/feedback/<id
