AGENTUM

AGENTUM (AGENTUM LTDA, a software company in Sertãozinho, São Paulo, Brazil, registered September 2026) is a "payment agent" data provider: eleven HTTP endpoints sold per call over the x402 protocol — USDC on Base mainnet (eip155:8453) — with no account, no API key and no subscription; an agent pays inside the request and receives the result in the same round trip. Nine routes on agentum.lat cover Brazilian and global company and market data (CNPJ registration status, CEP address lookup, CPF check-digit validation, Banco Central Selic/CDI/commercial-dollar rates, ECB FX rates, World Bank indicators, EU VIES VAT validation, GLEIF LEI lookup and an AI-summarised business-intelligence report on a CNPJ), and three on business.agentum.lat (AGENTUM Business) add counterparty compliance checks against TCU, CEIS/CNEP, CNJ and CVM plus a consolidated preflight verdict. The same routes ship as eleven tools in the @agentum/mcp-server npm package (stdio, the caller's own wallet pays), and AGENTUM Business is also an A2A 1.0 JSON-RPC agent with a card at business.agentum.lat/.well-known/agent-card.json. Partial OpenAPI 3.1 contracts, an llms.txt and an RFC 9116 security.txt are published; every paid route answers a genuine x402 v2 challenge with Bazaar discovery metadata and IETF RateLimit headers.

AGENTUM publishes 6 API contracts indexed on the APIs.io network, including Business Intelligence API, Company Intelligence API, Counterparty Verification API, and 3 more. Tagged areas include Company, Business Intelligence, KYB, Company Data, and Compliance.

AGENTUM’s developer surface includes documentation, pricing, authentication, and 26 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/agentum-lat: open an issue to ask a question, or submit a pull request to add artifacts.
