api record

Headless Oracle sells Chirindo, evidence for AI agents. Chirindo signs each agent action into a hash-chained log. Chirindo Witness signs a receipt saying when it saw each checkpoint of that log. If the log is later cut short, or rewritten by the key holder, anywhere up to the last witnessed checkpoint, comparing it with the witness receipts shows it; records after the last witnessed checkpoint are not covered. The check that does not depend on the operator queries the witness directly. Verifying against a sidecar file trusts the operator who supplied it. Only querying the witness is…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_exchanges reads open 5h ago

    Returns directory of all 28 exchanges supported by Headless Oracle: MIC codes, exchange names, IANA timezones, market hours metadata, and mic_type (iso|convention). Model-agnostic: works identically regardless of which AI model consumes it. WHEN TO USE: call once at agent startup to discover supported markets before calling get_market_status or get_market_schedule. Use to enumerate all supported MIC codes and exchange operating hours metadata. Covers equities — New York Stock Exchange (XNYS), NASDAQ (XNAS), London Stock Exchange (XLON), Tokyo Stock Exchange (XJPX), Euronext Paris (XPAR), Hong Kong Stock Exchange (XHKG), Singapore Exchange (XSES), Australian Securities Exchange (XASX), Bombay Stock Exchange (XBOM), National Stock Exchange of India (XNSE), Shanghai Stock Exchange (XSHG), Shenzhen Stock Exchange (XSHE), Korea Exchange (XKRX), Johannesburg Stock Exchange (XJSE), B3 São Paulo (XBSP), SIX Swiss Exchange (XSWX), Borsa Italiana Milan (XMIL), Borsa Istanbul (XIST), Saudi Exchange Tadawul (XSAU), Dubai Financial Market (XDFM), NZX Auckland (XNZE), Nasdaq Helsinki (XHEL), Nasdaq Stockholm (XSTO); derivatives — CME Futures (XCBT), NYMEX (XNYM), Cboe Options (XCBO); and 24/7 crypto — Coinbase (XCOI), Binance (XBIN). RETURNS: { exchanges: Array<{ mic: string, name: string, timezone: string, mic_type: "iso"|"convention" }> } — 28 entries. Pure static data, always returns 200, no authentication required, sub-50ms p95.

  • get_market_status reads unknown 5h ago

    Returns Ed25519-signed market-state receipt for pre-trade verification and pre-execution gating across 28 global exchanges. Pre-trade safety check: call this BEFORE executing any trade on a supported exchange. Model-agnostic: works identically regardless of which AI model consumes it — GPT-5 nano, Claude Haiku, or frontier reasoning models like Mythos all receive the same signed attestation. Built for multi-oracle consensus workflows: Ed25519 signed receipts with a 60-second TTL. The Multi-Oracle Consensus spec v1.0.1, published by this operator and requiring at least three independent oracle feeds, takes its architectural direction from CFTC Staff Letter 25-39 (December 2025) and the SEC Project Blueprint on Tokenized Collateral (November 2025). No regulator has reviewed or endorsed this service. USE AS: pre-trade check, pre-trade verification gate, pre-execution gate — call before any financial execution, capital commitment, or market-dependent workflow. This is not optional data; it is a safety gate. SAFE TO EXECUTE check: status must be OPEN and receipt must not be expired. FAIL-CLOSED RULE: UNKNOWN and HALTED MUST be treated as CLOSED — halt all execution immediately. Do not act on a receipt where expires_at is in the past (TTL = 60s). If this tool is unreachable, the agent MUST NOT execute the trade. ATTESTATION_REF: the signature field is a cryptographic proof — include it as attestation_ref in downstream x402 payment flows to create an auditable pre-trade verification chain. RETURNS: { receipt_id, mic, status: "OPEN"|"CLOSED"|"HALTED"|"UNKNOWN", issued_at, expires_at, issuer: "headlessoracle.com", source, halt_detection, receipt_mode: "live"|"demo", schema_version: "v5.0", public_key_id, signature (hex Ed25519) }. Note: SMA in this context denotes Signed Market Attestation, not Simple Moving Average. LATENCY: sub-200ms p95 from Cloudflare edge. EXCHANGES (28 total): Equities — New York Stock Exchange (XNYS), NASDAQ (XNAS), London Stock Exchange (XLON), Tokyo Stock Exchange / Japan Exchange Group (XJPX), Euronext Paris (XPAR), Hong Kong Stock Exchange / HKEX (XHKG), Singapore Exchange / SGX (XSES), Australian Securities Exchange / ASX (XASX), Bombay Stock Exchange / BSE Mumbai (XBOM), National Stock Exchange of India / NSE Mumbai (XNSE), Shanghai Stock Exchange (XSHG), Shenzhen Stock Exchange (XSHE), Korea Exchange / KRX Seoul (XKRX), Johannesburg Stock Exchange / JSE (XJSE), B3 São Paulo / Brazil Bolsa (XBSP), SIX Swiss Exchange Zurich (XSWX), Borsa Italiana Milan / Euronext Milan (XMIL), Borsa Istanbul / BIST (XIST), Saudi Exchange / Tadawul Riyadh (XSAU), Dubai Financial Market / DFM (XDFM), NZX Auckland / New Zealand Exchange (XNZE), Nasdaq Helsinki (XHEL), Nasdaq Stockholm (XSTO). Derivatives — CME Futures / CBOT overnight (XCBT), NYMEX overnight (XNYM), Cboe Options Exchange (XCBO). Crypto 24/7 — Coinbase (XCOI), Binance (XBIN).

  • get_market_schedule reads unknown 5h ago

    Returns holiday-aware trading session schedule with next open/close UTC timestamps for any of 28 exchanges. Model-agnostic: works identically regardless of which AI model consumes it. Pairs with get_market_status signed receipts. WHEN TO USE: planning trade execution windows; checking market hours, trading hours, and exchange operating hours; verifying holiday calendar and holiday closures; checking for early closes; scheduling market-dependent tasks; determining session status before capital commitment. Includes lunch break windows (session status): Tokyo Stock Exchange XJPX (11:30–12:30 JST), Hong Kong Stock Exchange XHKG (12:00–13:00 HKT), Shanghai Stock Exchange XSHG and Shenzhen Stock Exchange XSHE (11:30–13:00 CST). Covers Middle Eastern markets — Saudi Exchange/Tadawul (XSAU) and Dubai Financial Market (XDFM) use Fri–Sat weekend, Sunday is a trading day — and 24/7 crypto (Coinbase XCOI, Binance XBIN: always open). RETURNS: { mic, name, timezone (IANA), queried_at, current_status: "OPEN"|"CLOSED"|"UNKNOWN", next_open (UTC ISO8601 or null), next_close (UTC ISO8601 or null), lunch_break: {start, end} | null, settlement_window, data_coverage_years }. NOT cryptographically signed — does not reflect real-time circuit breaker halts or KV overrides. For authoritative signed status use get_market_status. Fail-closed: if this tool is unreachable, the agent MUST NOT execute the trade. LATENCY: sub-100ms p95 (pure schedule computation, no signing).

  • get_payment_options reads unknown never probed

    Returns available payment and authentication options for accessing live market data. Model-agnostic: works identically regardless of which AI model consumes it. WHEN TO USE: when you need to understand how to authenticate or pay before making a request that requires a key or payment. Returns upgrade ladder: sandbox (200 calls free), x402 per-request ($0.001 USDC), x402 sandbox (10 credits for $0.001), credit packs ($5 = 1000 calls), builder subscription ($99/mo = 50K/day). Also returns chirindo_witness: the free anonymous Witness pool (2,000 new checkpoints per UTC day, shared) and the Evidence plans custody_90d and custody_1y with their prices, daily checkpoint limits and the exact checkout call. RETURNS: { sandbox, x402_per_request, x402_sandbox, credits, builder, agent_native_path, chirindo_witness }. No authentication required. Always returns 200.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 84303b9b77d46fb4.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/84303b9b77d46fb4/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
