Cacheflow was a B2B SaaS billing, CPQ (configure-price-quote), and subscription-management platform that let software companies build interactive deal rooms, automate quote-to-cash, and offer buyers flexible payment and financing options. Founded in 2020 and backed by GGV Capital and GV, Cacheflow was acquired by HubSpot in 2024 and folded into HubSpot Commerce / HubSpot CPQ. The company shipped a substantial REST API — 305 paths and 400 operations across proposals, products, customers, subscriptions, billing schedules, usage, invoices, payments, refunds, approvals, e-signature and CRM/accounting integrations — and that contract is still publicly published: developer.getcacheflow.com serves a live ReadMe developer portal with an llms.txt and an OpenAPI 3.0.1 definition. The runtime is gone. As of 2026-08-13 api.getcacheflow.com, api.sandbox.getcacheflow.com, checkout, status and help all return NXDOMAIN, and getcacheflow.com 301-redirects to HubSpot's Commerce CPQ page. This profile therefore records a rare shape: a fully published, machine-readable API contract that outlived the API it described.
Cacheflow publishes 1 API on the APIs.io network. Tagged areas include Company, Fintech, Billing, Subscriptions, and CPQ.
The Cacheflow catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Cacheflow’s developer surface includes documentation, API reference, getting-started guide, authentication, sandbox, and 18 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.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

every runtime host (api., api.sandbox., app.sandbox., checkout., status., help., docs.) returns NXDOMAIN as of 2026-08-13.

x-pointer-notes:
omitted_deliberately: 'The following canonical pointers are NOT emitted because the underlying thing genuinely does not
exist on Cacheflow''s surface, and emitting them would be fabrication: SDKs (no client library on any registry), Idempotency
(zero occurrences of "idempoten" in the 400-operation contract), StatusPage (status.getcacheflow.com is NXDOMAIN), Deprecation
(no policy published; only 3 in-spec deprecated flags), Security and VulnerabilityDisclosure (no security.txt, no disclosure
page, no bug bounty), Compliance and TrustCenter (trust./security. subdomains are NXDOMAIN), WellKnown and SecurityTxt
(every /.well-known/ path 404s — see well-known/cacheflow-well-known.yml, which records the absence), AgentCard (agent-card.json
and agent.json 404 on every resolving host), AsyncAPI (a webhook surface exists but no AsyncAPI document was ever published),
ChangeLog (the ReadMe project has the changelog module disabled), CLI (the oclif client was never released to a registry),
Postman, Roadmap, Blog, Support, Pricing, SignUp, TermsOfService and PrivacyPolicy (all of those pages now 301 to HubSpot
and are HubSpot''s, not Cacheflow''s).'

artifacts_added: 23
pass: local-v1
note: Round 2 overturned round 1. The previous pass recorded "no independent Cacheflow API, developer portal, SDKs, or MCP
surface remains to harvest" after checking only the marketing domain, which 301s to HubSpot. STEP 0b contract discovery
found the live ReadMe developer portal at developer.getcacheflow.com, its llms.txt, and a real OpenAPI 3.0.1 (305 paths
/ 400 operations / 407 schemas) served from the ReadMe API registry the portal's own reference pages point at.
