SNHP

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 25 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-10-09 · rubric v0.23.0
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 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/snhp-dev: open an issue to ask a question, or submit a pull request to add artifacts.

  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.
