Denim

Denim (denim.com, formerly Axle Payments) is an all-in-one financial and back-office platform for freight brokers, trucking companies, and 3PLs. It provides freight factoring, invoicing, collections, carrier payments, and a fuel card, automating the broker back office and syncing two ways with transportation management systems. The Denim Public API (OpenAPI 3.0) exposes freight loads (jobs), debtors, payees, companies, factoring companies, and transactions, secured with an x-api-key header, so partners can create and quote jobs, onboard debtor/payee relationships, and reconcile transactions programmatically. Added to the API Evangelist network as a portfolio-company lead and enriched from the provider's public developer surface.

Denim publishes 6 API contracts indexed on the APIs.io network, including Companies API, Debtors API, Jobs API, and 3 more. Tagged areas include Company, Freight, Factoring, Payments, and Logistics.

The Denim catalog on APIs.io includes 1 Spectral governance ruleset.

Denim’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 21 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

8 more unmet checks in the Agent Readiness table above.
