TrySpansa is a YouTube sponsorship and influencer marketplace that lets brands discover and qualify YouTube channels by niche, audience size and engagement (144K+ channels across 30 niches, per its own listing), see CPM-based estimated sponsorship rates, send campaign briefs to creators, and fund deals through escrow on a commission-only model. It listed itself on a2aregistry.org as a 'YouTube sponsorship marketplace API' (discovery-only in v1), but as of 2026-09-19 tryspansa.com serves only a blank HTML shell on every path including its agent card, and no public API contract, documentation, SDK or developer portal is published anywhere.
TrySpansa is profiled on the APIs.io network. Tagged areas include Company, YouTube, Sponsorship, Influencer Marketing, and Creator Economy.
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 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/.

Agent readiness — checks not met, largest first (exact, from this profile):
Machine-Readable Auth+10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
13 more unmet checks in the Agent Readiness table above.

x-liveness: 200 on 2026-09-19 but the body is a blank noindex HTML shell (see x-coverage); the domain is verifiably TrySpansa's
own (a2aregistry.org provider.url, DNS on Vercel, MX on ImprovMX), so the pointer is kept.
x-coverage:
state: none
reason: no-developer-program
detail: The only public API claim is TrySpansa's own a2aregistry.org listing; its agent card at tryspansa.com/.well-known/agent-card.json
— like every path on the domain since a 2026-09-16 deployment, including /features, /pricing and /developers — returns
HTTP 200 with a 141-byte blank noindex HTML shell, the registry's own 2026-09-14 check recorded NO_TRANSPORTS for that
card, and api./docs./mcp.tryspansa.com answer Vercel DEPLOYMENT_NOT_FOUND, so no contract, docs, SDK or portal exists
to read.
