Agree.com

Agree.com is a contract-to-cash platform that combines free, unlimited e-signatures with invoicing, billing and integrated payments, positioning itself directly against DocuSign and Bill.com by giving the signature product away and monetizing the money movement that follows it. The company raised a $7.2M seed round led by Pelion Venture Partners in May 2025 after a $3M pre-seed led by Better Tomorrow Ventures. It markets an "agentic revenue operating system" built from named AI agents for contracts, billing, collections, recovery, reconciliation and insight. For developers it publishes a 56-operation REST API covering agreements, invoices, contacts, customers, cash-flow and recovery reporting, and webhooks, described by a real OpenAPI 3.0 document served anonymously at secure.agree.com/documentation/openapi, plus a hosted remote MCP server at secure.agree.com/mcp discoverable through RFC 9728 protected resource metadata and guarded by an OAuth 2.1 authorization server with PKCE and dynamic client registration.

Agree.com publishes 1 API on the APIs.io network: Agree API. Tagged areas include Agreements, Electronic Signature, Contract Management, Invoicing, and Billing.

The Agree.com catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Agree.com’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, authentication, and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/agree-com: open an issue to ask a question, or submit a pull request to add artifacts.
