Tools

Tools the server advertised in the latest measurement — measured, not catalog-claimed.

start_bitcoin_research1 param · 1 required
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.
- querystringrequired
select_bitcoin_research_product1 param · 1 required
FREE. FREE, no account required. Select a research product and inspect its price, free evaluation path, and contract using an explicit task: 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.
- taskstringrequired
search_bitcoin_knowledge2 params · 1 required
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.
- querystringrequired
- limitinteger
get_bitcoin_topic1 param · 1 required
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.
- idstringrequired
answer_bitcoin_question1 param · 1 required
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.
- querystringrequired
check_bitcoin_evidence_checkpoint2 params · 2 required
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.
- checkpointIdstringrequired
- expectedDigeststringrequired
verify_bitcoin_claim1 param · 1 required
PAID 0.50 USD via Stripe MPP. Evaluate a Bitcoin proposition against verdict-eligible maintained atomic claims and return a conservative rich verdict with supporting, conflicting, contextual, provenance, precision, and temporal evidence metadata. Determine whether a specific Bitcoin proposition is supported, contradicted, mixed, only partially verifiable, or not supported by enough maintained evidence.
- claimstringrequired
get_bitcoin_evidence_pack1 param · 1 required
PAID 0.50 USD via Stripe MPP. Build a focused Bitcoin evidence package that separates verdict-eligible atomic claims from contextual material and reports source authority, exact-locator precision, conflicts, caveats, provenance, and temporal scope. Collect supporting, conflicting, and contextual evidence around one focused Bitcoin research question with explicit evidence-quality metadata.
- querystringrequired
build_bitcoin_timeline4 params · 1 required
PAID 0.50 USD via Stripe MPP. Build a query-specific historical Bitcoin research timeline that distinguishes event dates, source dates, effective dates, source-level support, exact locators, and maintained re-verification boundaries. Put maintained Bitcoin events in chronological order while preserving source and temporal semantics.
- querystringrequired
- fromYearinteger
- toYearinteger
- limitinteger
deep_ground_bitcoin1 param · 1 required
PAID 1.00 USD via Stripe MPP. Produce a deeper deterministic Bitcoin research dossier across canonical topics, verdict-eligible atomic claims, contextual material, conflicting evidence, source hierarchy, exact-locator precision, temporal scope, history, and caveats. Ground a multi-topic Bitcoin research dossier while preserving what is proven, contextual, disputed, time-bounded, or insufficiently supported.
- querystringrequired
batch_bitcoin_research1 param · 1 required
PAID 2.50 USD via Stripe 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. Process multiple distinct Bitcoin claims, questions, or evidence requests while retaining the evidence standard for each item.
- itemsarrayrequired

Availability history

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.

Era history

Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
