73 Strings is an AI-powered financial technology company serving alternative asset managers in private equity, private credit, venture capital, infrastructure and multi-strategy funds. Its platform digitises the valuation and portfolio-monitoring lifecycle for illiquid assets through three products — 73 Value (audit-ready equity and credit valuations), 73 Monitor (portfolio monitoring and analytics) and 73 Extract (AI extraction of unstructured private-market documents into structured data). 73 Strings exposes a REST API surface through Microsoft Azure API Management developer portals, covering asset information, cap tables, documents, financial data, qualitative data and transaction-ledger ingestion, all authenticated with a subscription key and scoped by organization and user identifiers. The company is headquartered in Paris with offices in London, New York, San Francisco, Singapore, Riyadh, Abu Dhabi, Bengaluru and Hyderabad, and is backed by Blackstone, Goldman Sachs, Hamilton Lane, Golub Capital and Broadhaven.
73 Strings publishes 6 API contracts indexed on the APIs.io network, including Asset Info API, Documents API, Financial Data API, and 3 more. Tagged areas include Private Markets, Valuation, Portfolio Monitoring, Private Equity, and Private Credit.
The 73 Strings catalog on APIs.io includes 1 Spectral governance ruleset.
73 Strings’ developer surface includes authentication, documentation, API reference, signup flow, support, engineering blog, and 26 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/.

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
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
6 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.
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: Six real OpenAPI 3.0.1 documents (23 operations, 141 component schemas) were harvested from the 73 Strings Azure API
Management developer-portal Data API at api-accord-eut-73strings.developer.azure-api.net/developer/apis?api-version=2022-04-01-preview.
The portal's own anonymous OpenAPI export returns paths:{}, so operations, parameters, request/response representations,
published examples and component schemas were assembled from the same portal's /operations and /schemas endpoints. Two
sibling APIM instances (api-usa-73strings, api-73strings) publish no catalogue anonymously.
