NFTgo

NFTgo is an NFT data, analytics, and trading-aggregator platform that lets developers query NFT market data and execute transactions through a single REST API. The NFTgo Developer API spans several products: NFT Data (collection, token, owner, holder, rarity, and trait data across multiple chains), Charts & Market analytics (rankings, volume, market-cap, floor-price and holder charts), GoTrading (an aggregated order book plus create/fulfill/cancel listings and offers across OpenSea, Blur, LooksRare and X2Y2), GoPricing (machine-learning NFT valuations), and Notify (webhook-based real-time notifications). Requests authenticate with an X-API-KEY header against data-api.nftgo.io and are metered in Compute Units. NFTgo serves 3,000+ institutional customers and is backed by 500 Global.

NFTgo is listed with 1 API on the APIs.io network. Tagged areas include Company, NFT, Blockchain, Web3, and NFT Data.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

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 the provider profile at artifacts.apis.io/nftgo/apis.yml: open an issue on github.com/api-evangelist/nftgo to ask a question or point us at an artifact you publish.
