Scored across 22 tools
Most families are clearly separated (intelligence swarms vs. sync lookups vs. Front Door vs. Vault vs. notary), and descriptions actively steer between them. But real overlap remains: angel_intelligence vs. angel_deep_intelligence, company_intelligence vs. competitive_intelligence (an explicit alias), quick_brief vs. sourced_brief, and check_report_status vs. wait_for_report all answer nearly the same need.
Everything is snake_case, which helps, but the verb convention is mixed: verb_noun tools (check_balance, classify_entities, verify_provenance, vault_search) sit alongside bare noun-named run starters (angel_intelligence, due_diligence, security_assessment, quick_brief). The frontdoor_* group is internally consistent; the intelligence suite is not.
22 tools is borderline-heavy, though the domain genuinely spans several sub-products (intelligence runs, KYB, memos, local services, notary, vault). The count is inflated by near-duplicates: an alias tool, two polling tools, and tiered brief/intel variants that could be collapsed.
The core loop is closed: estimate_credits → run swarm → check/wait status → verify_provenance, with balance checks, KYB screening, notary minting, and vault retrieval filling out the surface. Minor gaps exist (no run history/listing, no cancel or delete of runs, no direct Vault file listing), but an agent can work around them.
Run an Angel Deep swarm (CI_ANGEL_DEEP) — Angel Intelligence plus community-traction signal and a deterministic traction score. Returns a run_id immediately; poll check_report_status until completed. Costs 90 credits.
Inputs: target (required), config.
Run an Angel Intelligence swarm (CI_ANGEL, 5 agents) — pre-seed/seed startup triage with a syndicate memo. Returns a run_id immediately; poll check_report_status until completed. Costs 50 credits.
Inputs: target (required), config.
Return the current credit balance for the authenticated account. Free.
Inputs: no named parameters.
Check the status of an intelligence run by its run_id, and retrieve the full report once it is completed. Free.
Inputs: report_id.
Classify candidate strings into company, person, technology, investor, product, funding_round, market, trend, or NOT_AN_ENTITY. Use this to type raw names before KYB or an intelligence run. Do not use it to verify a company (kyb_verify) or write a memo (quick_brief / sourced_brief). Pass target (one name + optional context) or candidates (1–20 {name, context?} objects); candidates wins if both are set. Sync — returns {results: [{name, type, confidence, reasoning}], credits_charged} immediately, not a run_id; do not poll. Costs 2 credits after a usable batch; empty input returns results=[] and charges 0. Does not create, delete, or overwrite user data; it only labels strings and may debit credits. Informational labels only — not verified fact.
Inputs: target, context, candidates.
Run Company Intelligence (CI, 5 agents) on one company — competitive landscape, threats, positioning. Optional config.company_domain improves grounding. Returns a run_id immediately; poll check_report_status until completed. Costs 100 credits.
Inputs: target (required), config.
Free sync company snapshot grounded in SEC EDGAR (0 credits). Returns headline/summary/filings + ladder to classify → Angel/CI. Informational triage only — not diligence.
Inputs: domain, target.
Alias for company_intelligence — full competitive-intelligence swarm on a company (CI, 5 agents). Returns run_id; poll check_report_status. Costs 100 credits.
Inputs: target (required), config.
Run a due-diligence (DD) swarm on a company or deal. Returns a run_id immediately; poll check_report_status until completed. Costs 200 credits.
Inputs: target (required), config.
Estimate credit cost before starting a run. Pass tool (MCP name, e.g. angel_intelligence) or endpoint (REST, e.g. angel-report). Omit both for the debiting catalog. Free — does not debit.
Inputs: tool, endpoint.
Find local service businesses (pool cleaning, pool repair, lawn care, landscaping; Florida Gulf Coast to start) from a plain-language request, e.g. "weekly pool cleaning in 34202 under $125/mo, Saturdays". Returns up to 5 matches with owner-approved price ranges, service days and openings, plus how to book. Prices are owner-approved ranges, not quotes; the owner confirms time and final price; nothing is charged. Free. If nobody matches, the unmet request is recorded so we can recruit businesses - never invent one.
Inputs: request (required), zip, unit, max_price_usd.
Get one Front Door business profile by slug: services with owner-approved price ranges, service days, ZIPs served, license line, openings and the booking contract. Prices are ranges, not quotes; the owner confirms time and final price; nothing is charged. Free.
Inputs: slug (required).
Send a service request to a local Front Door business on the person's behalf. Requires on_behalf_confirmed=true, which you may set only after the person has seen the business and price range and explicitly asked you to send their name and contact details. This does not guarantee a booking: the business owner approves or declines, confirms the time and final price, and nothing is charged. Prices are owner-approved ranges. Free.
Inputs: slug (required), service_key (required), service_zip (required), customer_name (required), +5 more.
Know Your Business is 1 credit on a signed-in account and emails a PDF. KYB Screen is $0.05 USDC with no account (Accept-Payment: x402) and returns JSON only. Same screen either way. Verify a business before onboarding, lending to, paying, or contracting with it. Screens one legal entity against four public records in a single call and returns a structured verdict: GLEIF legal-entity registry (identity, status, parent company), SEC EDGAR filings, the OFAC SDN sanctions list, and SAM.gov federal debarment/exclusions. Prefer this over a web search when you need a reproducible, citable answer to "is this company real, active, sanctioned, or barred from federal contracting?" — results are deterministic (no model in the loop) and every screen names its source. Screens are never silently skipped: any that could not run is listed in checks_unavailable and forces status "incomplete". A possible match is flagged for human review, never as a hit. When the typed name does not match one legal name, status stays not_found and different_legal_names lists other entities. Those names are different entities. Do not treat one of them as the company that was typed. Flag no_registry_record means the registry returned no legal name. Entities only, not individuals. Not a consumer report and not an FCRA eligibility decision. Optional notarize=true stamps a hash_only Notary evidence-pack receipt (included in the price; integrity, not factual truth).
Inputs: name (required), domain, notarize, jurisdiction.
Run Market Intelligence (CI_MARKET, 7 agents) on one coherent market category — topology, capital flows, emerging entrants, adjacent attackers. Pass a category phrase as target (e.g. "agentic coding tools for enterprise software teams"), not a list of topics. Optional config: market, vertical, geography, time_window. Returns a run_id immediately; poll check_report_status until completed. Costs 150 credits.
Inputs: target (required), config.
Mint a receipt for a SHA-512 content hash. Hash Stamp is the wallet price: $0.02 USDC, mode hash_only, no account. Notary Receipt is the account price: 1 credit for the same hash_only mint. Other modes are one price each: source_snapshot (1 credit), source_archive (3 credits), anchored (3 credits — Anchored inclusion proof). The stamp proves the hash is unchanged. It does not prove the content is true. Hash client-side first. Do not send the payload.
Inputs: content_hash (required), mode, sources, agent_label, +1 more.
Quick Brief. Starts a short memo and returns a run_id right away. Call check_report_status with that run_id until status is completed. Costs 20 credits after a usable memo. Informational only — not verified fact or professional advice.
Inputs: target (required), focus, context.
Run a Security Assessment (SECURITY, 5 agents) — public OSINT tech/security diligence brief (attack surface, disclosures, breach history, vendor stack, posture). Returns a run_id immediately; poll check_report_status until completed. Costs 75 credits. Not a pen test or attestation.
Inputs: target (required), config.
Sourced Brief. Starts a short cited memo and returns a run_id right away. Call check_report_status with that run_id until status is completed. Costs 3 credits after a usable memo. Informational only — not verified fact.
Inputs: target (required), focus, context, sources, +1 more.
Search the authenticated tenant's Vault and return ranked chunks (chunk_id, file_id, filename, chunk_index, text, score) plus hit_count. Raw retrieval only — no LLM narrative. Use this when you need passages from uploaded files. Use sourced_brief (sources including "vault") or quick_brief when you want a written memo. Requires a Ysaere account (not available keyless). Sync — returns hits immediately, not a run_id; do not poll check_report_status. Optional limit (1–20, default 8), min_similarity (0–0.99, default 0.35; higher drops weaker hits), and file_ids (max 50) to scope the search. Costs 5 credits. Does not create, delete, or overwrite files; it only reads the Vault and may debit credits.
Inputs: query (required), limit, file_ids, min_similarity.
Return the cryptographic provenance chain for a report so its content can be independently verified. Free. Integrity ≠ factual truth.
Inputs: report_id.
Poll an intelligence run until status is completed/failed/partial or timeout_seconds elapses (default 8, max 12). Returns the latest report payload (timed_out:true is success — call again or use check_report_status). Free — does not debit credits.
Inputs: report_id, timeout_seconds.
