SNHP (snhp.dev, operated by gametheory.dev / github.com/ryuxik and listed in the a2aregistry.org harvest as "Negotiation Copilot for Agents") is free, LLM-free game-theory negotiation math for AI agents: a hosted FastAPI "Game Theory Layer" with 74 operations served anonymously as OpenAPI 3.1 on snhp.dev that returns the math-optimal next move in a single-price or multi-issue negotiation in plain dollars, plus auction bidding and reserve pricing, mechanism design (Gale-Shapley, Myerson, posted-price clearance), a cryptographic first-strike commitment, and a verified-peer agent-to-agent flow that settles into signed AP2 Cart/Intent mandates. The same engine is exposed as a live streamable-HTTP MCP server with a 15-tool core door and a 54-tool pro door (listed in the official MCP registry and on Smithery), as a stdio server and Python library on PyPI (snhp, Apache-2.0), and behind an A2A agent card at the canonical well-known path. The core math is free with no key; a self-issued gt_* key unlocks a prepaid millicent wallet — funded by Stripe Checkout or agent-natively by the Machine Payments Protocol (Stripe Shared Payment Tokens) — that buys $2 receipted deterministic negotiation sessions and blind-custody encrypted agent memory, every settled call returning an Ed25519-signed receipt verifiable offline. A second application, the Evolution Arena on arena.snhp.dev, publishes its own OpenAPI for the live strategy-evolution sim, the gauntlet certificate and the PAR game. Single deployment, best-effort SLA stated in the API itself, no legal pages, GDPR access/erasure exposed as API operations.
SNHP publishes 23 API contracts indexed on the APIs.io network, including Arena API, Auctions API, Billing API, and 20 more. Tagged areas include Negotiation, Game Theory, AI Agents, MCP, and A2A.
SNHP’s developer surface includes documentation, API reference, getting-started guide, pricing, changelog, authentication, sandbox, and 26 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.
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/.
Show this score on your site.
It updates itself when the score changes. Paste this where you link to your API docs:

Agent readiness — checks not met, largest first (exact, from this profile):
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility+6 pts — a reversal operation in the contract, graded up when a window is documented too
Pagination+5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs
Agentic Commerce Well-Known Document+5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's
4 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

x-coverage:
state: covered
reason: null
detail: Fully covered. snhp.dev serves an anonymous OpenAPI 3.1 (74 operations) plus a second one on arena.snhp.dev (31),
a near-conformant A2A agent card at the canonical path, a live two-door MCP server that answers tools/list with no credentials
(15 + 54 tools), an MCP server card, agents.json, llms.txt on both hosts, machine-readable pricing and SLA in the API,
and a PyPI package; the repair-api-bases verdict "no-usable-base" is the .dev-TLD nonprod heuristic misfiring — https://snhp.dev
is the production host the provider's own agents.json names as http_base, so baseURL was left as stated.
