summary: >-
  Three projections of one HTTP surface plus one A2A-only capability. The MCP server is the widest published
  contract — eleven tools with zod input schemas — while the two OpenAPI documents together describe only
  seven operations, because the agentum.lat contract is partial by the provider's own statement. Six tools
  bind one-to-one to a declared operationId (the tool's route is literally that path). Five tools call routes
  that are live (each answered an x402 402 on 2026-09-19) but absent from the published OpenAPI, so their only
  machine-readable input contract is the tool schema and the Bazaar schema inside the 402 challenge. One REST
  operation (company) has no tool. The A2A company_intelligence skill overlaps the business host's registration
  routes; repo_intelligence has no REST twin at all.

  openapi:
  - {file: openapi/agentum-lat-apis-brasil-openapi.json, url: 'https://agentum.lat/openapi.json', gated: false, operations: 4, note: partial (4 of 9 live routes)}
  - {file: openapi/agentum-lat-business-openapi.json, url: 'https://business.agentum.lat/openapi.json', gated: false, operations: 3}

crosswalk:
- tool: verificar_cnpj
  category: company-registration
  rest: [verificarCnpj]
  binding: rest
  confidence: high
  note: Tool input cnpj (with or without punctuation, stripped to 14 digits) -> query parameter cnpj on GET /verificar-cnpj.
- tool: taxas_brasil
  category: market-rates
  rest: [taxasBrasil]
  binding: rest
  confidence: high
- tool: verificar_cep
  category: address
  rest: [verificarCep]
  binding: rest
  confidence: high
- tool: business_intelligence
  category: company-intelligence
  rest: [businessIntelligence]
  binding: rest
  confidence: high
  note: Tool input cnpj -> JSON requestBody {cnpj} on POST /business-intelligence.
- tool: company_intelligence_br
  category: compliance
  rest: [companyIntelligence]
  binding: rest
  confidence: high
  note: Cross-host — the tool lives in the same package but calls business.agentum.lat and pays a different wallet.

  category: counterparty-verification
  rest: [preflight]
  binding: rest
  confidence: high
mcp_only:
- tool: validar_cpf
  reason: Live route GET https://agentum.lat/validar-cpf?cpf= (402 observed) not declared in the published OpenAPI; input contract only in the tool schema and the challenge's Bazaar schema.
- tool: fx_rates
  reason: Live route GET https://agentum.lat/fx-rates?base=&symbols= (402 observed); not in the published OpenAPI.
- tool: economic_data
  reason: Live route GET https://agentum.lat/economic-data?country=&metric= (402 observed); not in the published OpenAPI. metric enum [gdp_growth, inflation, unemployment, population] is declared only in the tool.
- tool: vat_validate
  reason: Live route GET https://agentum.lat/vat-validate?country=&vat= (402 observed); not in the published OpenAPI.
- tool: company_enrich
  reason: Live route GET https://agentum.lat/company-enrich?name=|lei= (402 observed); not in the published OpenAPI.
rest_only:
- capability: company-registration
  operations: [company]
  note: GET https://business.agentum.lat/company?cnpj= ($0.02) — basic registration without the integrity check; the MCP server exposes company_intelligence_br and preflight from this host but not /company.
a2a_skills:
- skill: company_intelligence
  rest: [company, companyIntelligence]
  mcp: [company_intelligence_br]
  confidence: medium
  note: The card describes registration fields (legal name, status, legal nature, CNAE, address, Simples Nacional) from brasilapi with a receitaws fallback — the exact description of GET /company; it does not mention the TCU/CEIS/CNEP/CVM findings that companyIntelligence adds. Bound to both because the skill name matches the richer route and the description matches the basic one; not exercised.
- skill: repo_intelligence
  rest: []
  mcp: []
  confidence: high
  note: A2A-only. Delegates to the external DeepWiki MCP server (mcp.deepwiki.com); no AGENTUM HTTP route or tool exists for it.
