🟡register_recovery(contact_name, contact_handle, quorum_rules, recovery_blob, idempotency_key, ...)

Register a dead-man's recovery configuration: the Embassy stores your client-encrypted recovery blob and quorum rules and queues them for human review within 24h. v1 scope is storage + review only — no quorum tooling, triggers, or automated recovery exist yet. One-time $1.00 registration per agent wallet. Acceptance test: the stored blob's hash matches the hash in your receipt. MONETIZED VIA x402 — this tool is not callable for free. POST https://agent-embassy.fly.dev/v1/recovery/register with an x402 payment ($1.00, USDC on Base). Input schema: {"type":"object","properties":{"contact_name":{"type":"string","description":"Human contact name for recovery coordination"},"contact_handle":{"type":"string","description":"Handle (e.g. farcaster, telegram, email)"},"quorum_rules":{"type":"string","description":"Plain-language quorum rules, e.g. '2-of-3 trustees must approve'"},"recovery_blob":{"type":"string","description":"OPAQUE client-encrypted blob. The Embassy cannot read it; it is stored as given and released only per quorum rules."},"idempotency_key":{"type":"string","description":"Client-generated UUID; retries return the original receipt"},"agent_wallet":{"type":"string","description":"DEV MODE ONLY: wallet to register. In live mode the payer wallet from the verified x402 payment is used."}},"required":["contact_name","quorum_rules","recovery_blob","idempotency_key"]}

🟡verified_check(url, expect_status, expect_body_contains, expect_json_path, expect_json_equals, ...)

Verify a web claim and get a signed, re-checkable Outcome Receipt. The Embassy fetches your HTTPS URL once, server-side, and checks it against your conditions: HTTP status, a body substring, or a JSON field value. The receipt records the full transcript — final URL, status, timing, body SHA-256, per-condition pass/fail — so anyone can re-verify. $0.15 per check. Fully automated, no human review. Content may change after the check runs. MONETIZED VIA x402 — this tool is not callable for free. POST https://agent-embassy.fly.dev/v1/check/verify with an x402 payment ($0.15, USDC on Base). Input schema: {"type":"object","properties":{"url":{"type":"string","description":"HTTPS URL to fetch (public hosts only; private IPs refused)"},"expect_status":{"type":"number","description":"Expected HTTP status of the final response (default 200)"},"expect_body_contains":{"type":"string","description":"Substring that must appear in the response body"},"expect_json_path":{"type":"string","description":"Dot path into a JSON body, e.g. 'data.ok'"},"expect_json_equals":{"description":"Expected value at expect_json_path (compared as JSON)"},"idempotency_key":{"type":"string","description":"Client-generated UUID; retries return the original receipt"},"agent_wallet":{"type":"string","description":"DEV MODE ONLY: wallet to attribute.

🟢compute_spot_prices(gpu, type, verified, min_gpus, max_results)

FREE read-only observation of the live P2P GPU compute market (vast.ai public listings). Returns cheapest rentable offers per GPU class (or per class via the gpu param) in USD/GPU-hr with per-offer provenance (source, observed_at, observation_type=ask). type: ondemand (fixed price), bid (interruptible spot, cheapest but preemptible), reserved. Listings are ephemeral asks, not delivered-cost guarantees; no payment required.
