p0stman is an AI-native product studio operated by Thrive Venture Labs Ltd (Norfolk and London, UK), founded by Paul Gosnell. It builds AI voice agents, AI automation, operations command centres, rapid MVPs and "agentic web readiness" rebuilds for clients at fixed prices from £1,500-£8,000, and it uses its own site as the demonstration: p0stman.com serves a live anonymous MCP server at /api/mcp (five tools, JSON-RPC 2.0, protocol 2024-11-05), an A2A agent card for its assistant "Zero" at /.well-known/agent-card.json with a task endpoint at /api/agent, machine-readable JSON at /api/ai/context, /api/ai/services and /api/ai/portfolio, plus llms.txt, agents.md, context.md and a root mcp.json manifest. No OpenAPI, SDK, OAuth surface or developer sign-up is published - the whole API is free, anonymous and read-mostly, with two write tools that book a discovery call or send an enquiry. Not the Postman API platform.
p0stman is listed with 3 APIs on the APIs.io network. Tagged areas include AI Agents, MCP, A2A, Agentic Web, and Voice AI.
p0stman’s developer surface includes documentation, getting-started guide, support, pricing, engineering blog, authentication, and 25 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) 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 could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/.
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/p0stman-com: open an issue to ask a question, or submit a pull request to add artifacts.
