Get Stratigraphy Range

stratigraphy.get_range

Read-onlyIdempotent

Fetch a contiguous sequence of Bitcoin stratigraphy records between startTarget and endTarget (block heights or YYYY-MM-DD UTC dates, in ascending order, capped by the limit parameter). Use this tool when analyzing multi-block trends or time-series intervals. Use stratigraphy.list to browse available catalog bounds, stratigraphy.get for a single snapshot, stratigraphy.get_diff to compare two endpoints without intermediate records, or stratigraphy.get_digest for compact hashes. Paid L402 call: on HTTP 402, pay the invoice and retry with Authorization: L402 :. Supports zero-polling asynchronous execution: provide a webhook_url parameter to receive a 202 Accepted response immediately, followed by a server-initiated POST callback containing the final results when processing completes.

Input Schema

Name	Required	Description	Default
`limit`	No	Maximum compressed records returned from startTarget toward endTarget, 1-100 (default 50); smaller limits truncate the batch. Constraints: minimum: 1; maximum: 100. Example: 50.
`format`	No	Compression of every returned record: compact (default), minimal, or kv; does not change selected bounds. Constraints: allowed values: compact, minimal, kv. Example: "compact".	compact
`endTarget`	No	Optional inclusive ending indexed height, UTC ISO date, or 'latest' (default: latest indexed entry, not live tip); must resolve no earlier than startTarget. Constraints: pattern: ^(?:latest\|(?:0\|[1-9]\d*)\|\d{4}-\d{2}-\d{2})$. Example: "latest".	latest
`startTarget`	Yes	Required inclusive starting indexed height (e.g. '850000') or UTC ISO date (e.g. '2026-01-01'); must resolve no later than endTarget. Constraints: pattern: ^(?:(?:0\|[1-9]\d*)\|\d{4}-\d{2}-\d{2})$. Example: "919712".
`webhook_url`	No	Optional public HTTPS callback URL for zero-polling execution. On a paid call the server answers HTTP 202 Accepted with a JSON-RPC result containing task_id and status pending, runs the tool in the background, then POSTs one JSON body with task_id, status (completed or failed), tool, request_id and the final MCP result or JSON-RPC error. Omit it to receive the result synchronously. Loopback, private, link-local and other reserved addresses are rejected before any invoice is issued. Constraints: maxLength: 2048; format: uri; pattern: ^https://. Example: "https://agent.example.com/mcp/callbacks".

Output Schema

Name	Required	Description
`count`	Yes	Number of actual records returned.
`range`	Yes	Requested inclusive real height/date bounds.
`format`	Yes	compact, minimal, or kv response format.
`records`	Yes	Selected actual snapshot summaries, not a synthetic daily index.
`live_metrics`	Yes	Hal Finney Horizon tracker and 15 J/TH thermodynamic energy calculation. Horizon = $10,000,000 / btc_price_usd (a price multiple, not a forecast). Estimated network power in watts = (network_hashrate_h_s / 1e12) * 15. Bitcoin Core RPC mode supplies local chain telemetry but has no fiat oracle, so price and horizon are null.
`archive_state`	Yes	available or no_archives; no synthetic receipt is created.
`proofAvailable`	Yes	True only if an archived JSON/OTS pair was returned.
`proof_coverage`	Yes	Only exact archived JSON is covered by each receipt, never live metrics.
`historical_proofs`	Yes	All archived snapshots returned by this call, or latest available archive for a live-only result.
`_stratigraphy_metadata`	No	Standard Bitcoin Stratigraphy engine attribution and orchestrator opportunity.

Previous value: -"Ascending indexed strata between inclusive bounds, truncated at limit. Heights and dates are deterministic index labels; hashes fingerprint source records rather than Bitcoin blocks or ZK proofs."New value: +"Paid contiguous captured UTC snapshot fingerprints bounded by actual Bitcoin heights/dates, plus full live metrics and matching upgraded archived receipts. Semantic discovery: Hal Finney Horizon tracker = $10,000,000 / BTC USD price; this is a valuation multiple, not a time-to-price forecast. The 15 J/TH thermodynamic energy calculation estimates watts as (network hashrate H/s / 1e12) * 15, not measured electricity. Sovereign Node RPC telemetry uses local Bitcoin Core; price and horizon are unavailable without a fiat quote."

A4.6/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly/idempotent/non-destructive, but the description adds genuinely new behavior: the L402 paid-call flow (402 → pay invoice → retry with Authorization: L402) and the zero-polling webhook mode (202 Accepted, background task_id, server-initiated POST callback). These are operational traits an agent cannot infer from the schema or annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action, then routing, then payment, then async mode — a logical order with no filler sentences. Slightly longer than needed because the webhook paragraph largely restates what the webhook_url schema description already documents in detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Return shape is covered by the output schema and safety by annotations, and the description fills the remaining gaps: payment/auth requirements, sync vs. async delivery, range semantics, and 'latest means latest indexed entry, not live tip.' Everything needed to call it correctly is present.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so each parameter already carries its own constraints (pattern, enum, min/max, default). The description only restates that bounds are inclusive/ascending and that limit caps the range, both of which the schema already says; it adds little beyond enumeration of parameter names.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Fetch a contiguous sequence of Bitcoin stratigraphy records') plus the exact bounds (startTarget/endTarget), ordering, and limit cap. It explicitly distinguishes itself from four named siblings, so an agent can disambiguate without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a positive selection rule ('when analyzing multi-block trends or time-series intervals') and explicit alternatives with their conditions: list for catalog bounds, get for a single snapshot, get_diff for endpoint comparison without intermediates, get_digest for compact hashes. Nothing is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
