POLICYANDPLAY LTD

POLICYANDPLAY LTD (England & Wales, company no. 17253846) operates fetch-price, a UK product and price search API built for AI agents: one POST to api.fetch-price.com returns live eBay UK listings (via the official Browse API; Amazon UK rolling out) as normalised JSON with GBP prices, condition and an affiliate-tracked purchase URL. The free tier needs no API key (50 lookups/month, 30 requests/minute); Pro (GBP 29) and Scale/Trade (GBP 99) plans raise quotas and let customers route affiliate commission to their own eBay Partner Network account. The same API is exposed as a conformant A2A 1.0.0 agent card with a live JSON-RPC message/send binding, a stdio MCP server listed in the official MCP registry, a provider-authored SKILL.md, llms.txt, and npm/PyPI SDKs. No OpenAPI is published; the profile's spec was generated by API Evangelist from the provider's own reference and checked against the live host.

POLICYANDPLAY LTD publishes 4 API contracts indexed on the APIs.io network, including Agents API, Products API, Service API, and 1 more. Tagged areas include Company, Price Comparison, Product Search, E-Commerce, and Affiliates.

POLICYANDPLAY LTD’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, authentication, and 24 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 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/.
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/fetch-price-com: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
