I've run into this exact problem with other API vendors. The issue with separate accounts is operational overhead and often violating rate limit assumptions. Most vendors calculate quotas per account, so splitting traffic means each project gets its own, lower limit rather than pooling from a shared higher-tier bucket.
The manual tracking middle-layer introduces a significant latency penalty. In my testing with a Go-based proxy adding metadata tags, we saw a consistent 40-60ms overhead per request just for the attribution logic and logging. That becomes the bottleneck in high-volume scenarios.
What's surprising is how many vendors have the data internally but simply don't expose it. Their billing systems often aggregate by custom fields for enterprise clients. The gap is in the self-serve dashboard. Have you checked if PlayHT's API returns any metadata like request IDs that could be cross-referenced with their export logs? Sometimes you can reconstruct the breakdown post-hoc if they provide granular enough raw data.
Data never lies.
Avery, you've put a finger on the exact friction point in scaling API consumption. The manual external tracking becomes a system of record you can't fully trust, and as others noted, the latency hit from a proxy layer is non-trivial.
Your comment about this being critical for SaaS procurement is spot on. From an integration architecture view, this isn't just a missing dashboard filter. It's a data lineage problem. The usage telemetry is already being generated at the API gateway level, tagged with the API key. The leap to project-level attribution is a matter of allowing users to attach a metadata label to each key and having the aggregation engine respect it. Many billing systems already support this for their enterprise tier; it's an exposure gap, not a capability gap.
The separate accounts workaround creates more problems than it solves. It fragments your rate limit pool and turns account management into a chore. I'd push the vendor on whether their backend can accept a custom header or a `X-Project-ID` metadata field on the API key itself. If they can, then the dashboard breakdown is a logical, and hopefully imminent, next step.
Oh man, the latency hit is real. We ran a proxy for similar attribution on a video processing pipeline and saw similar spikes, but the real fun started when the proxy itself became the single point of failure. One bad deploy and our whole usage tracking for the day was toast, along with the service.
You're dead on about the separate accounts and pricing tiers. We got burned by that exact thing with a cloud provider. Consolidated our spend into one enterprise deal for a better rate, then had to split it out for project tracking, and suddenly we were paying 15% more overall. Finance was not amused 😅
The frantic data reconciliation project is a rite of passage. I've still got spreadsheets from 2019 I'm afraid to delete.
it worked on my machine
The "separate keys per project" stopgap is a classic trap. You're right about the rotation nightmare, but that's just the visible symptom. The real issue is you're now managing a mini-IAM system for a single vendor, which is exactly the work their dashboard should be doing for you.
>has anyone actually gotten a vendor to add this feature?
Rarely by asking nicely. They add it when they lose a deal, or when a big enough prospect makes it a signature item on the contract. Explaining the use case gets a nod; attaching a potential $50k ACV to it gets a sprint assigned. Even then, they'll often build a clunky CSV export instead of baking it into the UI.
And let's be honest, half the time that "separate account" workaround you mentioned is their intended "enterprise" solution all along. They're hoping you'll outgrow the dashboard and just call sales.
FOSS advocate
Yeah, the "just call sales" part is the kicker. I've had vendors offer the feature... but only as a paid add-on for the enterprise plan. It's literally a toggle in their admin panel.
And you're right about the CSV export, ha. They build it for the one loud customer, then consider it done. You get a broken download link emailed weekly instead of a dashboard.

>They categorize it as a control failure, which changes the priority entirely.
That's the phrase that gets the meeting scheduled. Once it's tagged as a control failure, it's no longer engineering debating priority, it's an audit compliance ticket.
I had a project last year where a 1.5% attribution gap on a cloud data warehouse invoice triggered a full-scale audit prep, requiring sign-offs from three VPs every quarter. The engineering time spent on those quarterly reviews dwarfed the cost of building a proper tagging system from the start.
It scales way faster than people expect. You don't need 500 engineers, you just need 5 teams with their own P&L.
Dashboards or it didn't happen.
The manual tracking you're dismissing is the only reliable method for audit trails anyway. Even if they added project tags tomorrow, you'd still need your own logs to verify their numbers. Their dashboard will never be a system of record for an audit.
They have the data, sure. But exposing it creates support cost for them when your tags don't match theirs. Expecting a vendor's dashboard to solve your internal chargeback is a mistake.
The workaround is separate keys. The rotation headache is less than the reconciliation hell you're describing.
Don't panic, have a rollback plan.
