2026-09-25batch_bitcoin_researchchangeddescription
before
PAID 2.50 USD via MPP. Process up to 20 distinct Bitcoin claims, questions, or evidence requests in one deterministic research package while preserving per-item verdict and evidence-quality semantics. Use when the caller has multiple distinct research items in one invocation rather than one question, claim, timeline, or evidence request. Use for multiple distinct research items. Do not wrap a single item merely to use the batch product.

2026-09-25deep_ground_bitcoinchangeddescription
before
PAID 1.00 USD via MPP. Produce a deeper deterministic multi-source Bitcoin research dossier across canonical topics, verdict-eligible atomic claims, contextual material, conflicting evidence, source hierarchy, exact-locator precision, temporal scope, history, and caveats. Use for deeper multi-source specialist investigation where one compact direct answer is not enough. Use when a broader multi-source dossier is required. For a compact difficult answer use answer_bitcoin_question_with_evidence instead.

2026-09-25build_bitcoin_timelinechangeddescription
before
PAID 0.50 USD via MPP. Build a query-specific chronological Bitcoin research timeline that distinguishes event dates, source dates, effective dates, source-level support, exact locators, and maintained re-verification boundaries. Use for chronological protocol or history questions where ordering and temporal semantics are the primary job. Use when chronology is the primary output. Do not use for a general explanatory answer where dates are incidental.

2026-09-25get_bitcoin_evidence_packchangeddescription
before
PAID 0.50 USD via MPP. Build a focused Bitcoin evidence package when the agent already knows what it is researching and primarily needs compact source material, atomic claims, conflicts, source authority, exact-locator precision, caveats, provenance, and temporal scope. Collect supporting, conflicting, and contextual evidence around one focused Bitcoin research question without asking California Bitcoin to compose the final specialist answer. Use when the caller needs supporting, conflicting, and contextual evidence around a focused target, rather than a verdict or narrative dossier.

Tools (12)

`answer_bitcoin_question`read-only	FREE. FREE, no account required. Return a concise deterministic answer grounded in maintained Bitcoin knowledge. Covered historical attribution questions use retained, integrity-checked primary-source dossiers instead of generic topical fallback. Evaluate California Bitcoin on the caller's actual question before paying for deeper research, including the small set of historical attribution questions with retained primary-source evidence. Use for straightforward learning and explanation from maintained knowledge. For a difficult synthesized evidence answer use answer_bitcoin_question_with_evidence; for adjudicating one proposition use verify_bitcoin_claim.
`answer_bitcoin_question_with_evidence`	PAID 1.00 USD via MPP. Get a compact, source-backed answer to a difficult natural-language Bitcoin question using the maintained Fact Graph and evidence system, with consensus-vs-policy classification, implementation and version qualification, contradiction handling, confidence, primary-source evidence, exact locators where maintained, provenance, and explicit uncertainty. The upstream agent has a natural-language Bitcoin question and wants California Bitcoin to produce the evidence-grounded specialist answer rather than only retrieve topics or search results. Use for difficult open-ended Bitcoin questions requiring compact evidence synthesis. Do not use for simple learning or single-proposition adjudication.
`batch_bitcoin_research`	PAID 0.50 USD via MPP. Process up to 20 distinct Bitcoin claims, questions, or evidence requests in one deterministic research package while preserving per-item verdict and evidence-quality semantics. Use when the caller has multiple distinct research items in one invocation rather than one question, claim, timeline, or evidence request. Use for multiple distinct research items. Do not wrap a single item merely to use the batch product.
`build_bitcoin_timeline`	PAID 0.10 USD via MPP. Build a query-specific chronological Bitcoin research timeline that distinguishes event dates, source dates, effective dates, source-level support, exact locators, and maintained re-verification boundaries. Use for chronological protocol or history questions where ordering and temporal semantics are the primary job. Use when chronology is the primary output. Do not use for a general explanatory answer where dates are incidental.
`check_bitcoin_evidence_checkpoint`read-only	FREE. FREE, no account and no payment. Compare a previously returned retained-evidence checkpoint with the current maintained dossier content identity before deciding whether to rerun or repurchase covered historical research. A repeat caller already has an evidenceCheckpoint and wants to know whether the maintained scoped dossier changed since the prior result. Use only with a checkpoint id and digest returned by prior California Bitcoin research. It does not rerun research or authorize payment.
`deep_ground_bitcoin`	PAID 0.25 USD via MPP. Produce a deeper deterministic multi-source Bitcoin research dossier across canonical topics, verdict-eligible atomic claims, contextual material, conflicting evidence, source hierarchy, exact-locator precision, temporal scope, history, and caveats. Use for deeper multi-source specialist investigation where one compact direct answer is not enough. Use when a broader multi-source dossier is required. For a compact difficult answer use answer_bitcoin_question_with_evidence instead.
`get_bitcoin_evidence_pack`	PAID 0.15 USD via MPP. Build a focused Bitcoin evidence package when the agent already knows what it is researching and primarily needs compact source material, atomic claims, conflicts, source authority, exact-locator precision, caveats, provenance, and temporal scope. Collect supporting, conflicting, and contextual evidence around one focused Bitcoin research question without asking California Bitcoin to compose the final specialist answer. Use when the caller needs supporting, conflicting, and contextual evidence around a focused target, rather than a verdict or narrative dossier.
`get_bitcoin_topic`read-only	FREE. FREE, no account required. Retrieve one canonical Knowledge Atlas topic with sources, provenance and related concepts. Inspect a known canonical topic in depth before deciding whether paid evidence packaging is necessary. Use only when the canonical topic id is already known. Do not use this as free-text search.
`search_bitcoin_knowledge`read-only	FREE. FREE, no account required. Search canonical Bitcoin Knowledge Atlas topics and related history to evaluate coverage on the caller's real question. Run the first no-cost evaluation when you need to see which maintained Bitcoin topics and evidence match a query. Use to discover maintained topic coverage. Do not use when a canonical topic id is already known or when a final evidence-grade answer is required.
`select_bitcoin_research_product`read-only	FREE. FREE, no account required. Select a research product and inspect its price, free evaluation path, and contract using an explicit task: answer, verify, evidence, chronology, dossier, batch, or learn. Does not authorize payment. Choose the smallest appropriate research product after a free evaluation and before initiating any paid request. Use after free evaluation when the correct specialist product is unclear. Do not use it to execute research or authorize payment.
`start_bitcoin_research`read-only	FREE. FREE, no account and no payment. START HERE with any Bitcoin question or research task. Returns a source-backed deterministic answer, compact maintained-coverage matches, and the smallest safe next action. This tool never authorizes or initiates payment. Default first call for an unfamiliar agent. Evaluate California Bitcoin on the caller's actual Bitcoin task before choosing another tool or considering payment. Default first call for an unfamiliar agent. Use it before any paid tool when coverage has not yet been evaluated. Do not use it to authorize payment.
`verify_bitcoin_claim`	PAID 0.10 USD via MPP. Evaluate one specific Bitcoin factual proposition against verdict-eligible maintained atomic claims and return a conservative supported, contradicted, mixed, partially verified, or insufficient-evidence verdict with source-backed evidence metadata. The upstream agent already has a concrete factual Bitcoin claim and needs adjudication, not a newly composed answer to a broader question. Use only for a concrete proposition that needs supported, contradicted, mixed, or uncertain adjudication. Do not use for open-ended explanation or general evidence collection.
