HostDeFi

HostDeFi is a non-custodial Solana token-risk service that scans a mint before a purchase — mint and freeze authority state, liquidity depth and lock status, holder concentration, dangerous Token-2022 extensions, sell simulation and contract flags. The public contract is an OpenAPI 3.1 document of 32 operations served from hostdefi.com/api with API-key authentication. HostDeFi also exposes an x402 machine-payment surface: an authority quick-check endpoint that returns HTTP 402 with a signed payment challenge, priced in USDC and payable on either Solana or Base, so an agent can buy a single check without an account.

HostDeFi publishes 7 API contracts indexed on the APIs.io network, including Token Risk API, Analyze Token API, Health API, and 4 more. Tagged areas include Solana, Token Risk, DeFi, rug pull, and x402.

HostDeFi’s developer surface includes authentication, pricing, support, and 23 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/.

Markets this provider is in provisional

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
x402 Micropayments & Agentic Pay-per-Call	undeclared	-	1	1

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.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

  note: 'Submitted via apis.io/add on 2026-08-20 (twice, as "HostDeFi" and "HostDeFi Token Risk API" — one provider, two records
    at the gate). The submitted APIs.json URL, https://hostdefi.com/apis.json, returns 404 against a control that also 404s,
    so the 404 is real; that is a bad pointer in the submission, not an absent surface. NO API-CATALOG IS RECORDED, DELIBERATELY.
    https://hostdefi.com/.well-known/api-catalog returns HTTP 200, but the body is the site''s HTML homepage, not a linkset.
    Recording it as an APICatalog would hand HostDeFi credit for a discovery document it does not serve. The path answering
    200 is not the same as the artifact existing. The x402 surface was verified live. GET /api/v1/x402/authority/solana/{mint}
    without a payment header returns HTTP 402 with x402Version 1 and two `accepts` entries — USDC on Solana and on Base, maxAmountRequired
    5000, 60-second timeout, with a named feePayer. The saved challenge in finops/ is that response verbatim. The REST API
    was probed at /api/v1/health and returned 200. One thing for the provider rather than for us: the published contract lists
    a second server, https://awake-integrity-production-faa0.up.railway.app, which also answers /v1/health with 200. That
    looks like a staging backend reachable from a production specification.

    CORRECTION, recorded because it matters more than the finding. This record was first built by hand from llms.txt plus
    probed paths, and it UNDER-reported the provider. The Add-API gate''s own stub named two artifacts the hand pass missed,
    and both are real: a hosted MCP server at https://hostdefi.com/api/v1/mcp, which answers tools/list anonymously with NINE
    tools, and an x402 discovery manifest at https://hostdefi.com/.well-known/x402 serving application/json with x402Versions
    [1,2], a payTo address and a facilitator. The MCP tools carry their own prices in their descriptions: scan_token and get_x402_pricing
    are free, token_risk_verdict $0.01/call, pregrad_signals $0.03, radar_alerts $0.01, x402_provider_risk $0.02, swap_evm_quote
    $0.01, swap_evm_price $0.002, and buy_api_key $5 as a single payment that mints a 30-day Agent-plan key -- an agent can
    buy its own credential. Guessing paths and reading llms.txt was not sufficient here; the gate''s discovery was better
    than the hand pass.'
