Your call doesn't stop at the API.
One request fans out through services that call other services — payments, auth, models, subprocessors. The risk surface expands with every hop, into code you never see and never agreed to trust. Manifide verifies the whole chain before the call leaves.
One call. Every hop verified.
There's a standard for what an API does. Nothing for whether you should call it.
OpenAPI describes the contract. Everything else that decides whether you should actually use a service still lives in pricing pages, PDFs, and sales decks — none of it machine-readable, none of it verified, none of it checked again to see if it's still true.
What does it cost, and how?
Per request? Per token? Tiered? It's on a pricing page a machine can't parse.
How is it secured — and where does your data go?
Scattered across a trust page and a security questionnaire no one reads too hard.
Is any of it still true today?
Nobody monitors it. The pricing changed, the cert lapsed, the region moved. You'd never know.
TLS for what an API does.
Your browser verifies a TLS certificate locally, in milliseconds, on every connection — then proceeds, or refuses. TLS made transport trust machine-native. Manifide does it for the part nobody certified: pricing, limits, auth, security, data residency, compliance.
Declarative, not normative
We never say an API is “good.” We make its properties explicit, comparable, and consumable — and state how each was established. We expose; your policy decides.
Composable, not standalone
A certificate chains the pinned certs of what the API is built on — its host, its model, its subprocessors — and computes the effective trust of the whole service, the way an SSL chain runs to a root.
Continuous, not static
Every claim carries a live status and a freshness window. You can always tell an API that was trustworthy from one that's still maintained.
Machine-first and runtime-verifiable
Certificates verify locally, in the hot path of a request — by a gateway, a CI pipeline, or an agent before it makes the call — using a short-lived signed status token, exactly as TLS staples revocation.
Your call doesn't stop at the API.
Every call is really a chain: the API you chose, the host it runs on, the services it calls onward. Manifide verifies the whole chain before the call leaves — and collapses it to one verdict you can act on.
The API you chose
Its contract, pricing, limits, auth, and security posture — each a claim with provenance and a freshness window.
The host it runs on
Residency, SOC 2, the IaaS it sits on — inherited and composed, not re-declared per API.
The services it calls onward
The model provider, the subprocessors three hops down. The runtime supply chain nobody else monitors.
A consumer that needs the truth — and the means to keep proving it.
The agent can't tolerate the theater
An AI agent choosing and calling APIs can't read a brand or skim a pricing page. It needs a structured, verifiable fact — or it has nothing to stand on. The consuming side's intolerance of theater is finally structural.
Monitoring is finally feasible
A certificate is only worth anything if it stays true. Keeping it continuously verified at scale was science-fiction a decade ago. The load-bearing piece has shipped.
Demand drags supply.
Consumption-side assurance, kept honest by reuse. A consumer compels a provider to certify; the certificate is issued once and reusable by everyone who depends on them.
CISOs, platforms, and agents
Compel the providers you depend on, evaluate every external API against your policy, and know the moment one drifts out of compliance — not at next year's review.
For consumers →ProvidersAPI & service providers
Prove it once and clear every customer. One reusable, machine-readable certificate instead of a hundred questionnaires — and a standing presence in the trust graph.
For providers →Truth has to become cheaper than theater.
