Blockchair API

Name: PubFi
Brand: PubFi

Blockchair API is an automation-built evidence profile for Blockchair public API resources. Discovery has historical docs evidence, but the official docs and homepage freshness locators are currently unreachable to machine fetches and PubFi does not certify gateway runtime support for this provider

Best fit and tradeoffs

Best for

Evaluating Blockchair public API docs
They want an internal starting point for evaluating Blockchair API documentation.
They need to compare Blockchair against nearby crypto data providers before runtime integration work.
They want claim-safe evidence that can be promoted later when source freshness and adapter certification are both clear.

Watchouts

Assuming PubFi gateway availability without adapter certification
Automation-built profiles may have incomplete category, pricing, quota, or endpoint coverage until deeper docs parsing runs.
Public docs evidence does not prove credential availability, commercial approval, uptime, or PubFi gateway runtime support.
Teams should verify endpoint shape, authentication, quotas, and terms before treating the provider as production-callable.

Why teams choose it

Blockchair API is an automation-built evidence profile based on public API corpus evidence. It helps teams inspect Blockchair docs, product naming, and on chain state fit before any runtime adapter or commercial approval work begins.

Discovery keeps this profile behind noindex and out of LLM export because the official docs and homepage freshness locators are currently unreachable to machine fetches. Inclusion means public evidence was processed for follow-up review, not that PubFi has certified gateway routing, credentials, x402 payment, MCP tooling, or supplier procurement for Blockchair.

PubFi gateway

Not present in the active Registry

The active signed Registry generation has no route for this provider. Discovery inclusion and upstream documentation do not make a provider executable through PubFi.

Runtime status: not_present
Active capabilities: 0
PubFi auth headers: Authorization: Bearer <PubFi API key>
Typed contract: Runtime OpenAPI

Use the official provider documentation for direct integration.
A future collected source becomes executable only after the normal evidence, policy, health, and generation pipeline accepts it.

Implementation notes

Docs

Medium

Review Blockchair public docs, authentication requirements, and the unreachable docs and homepage freshness locators before any adapter certification work starts.

Coverage

Medium

Treat the current Blockchair API profile as processed evidence, not as complete coverage of every chain, endpoint, or product surface.

Schema

Low

Use endpoint-specific docs evidence before deriving runtime request or response contracts.

Use cases

Compare Blockchair API evidence before runtime integration work

Comparison snapshot

Blockchair API should be compared with providers that cover similar on chain state workflows. The current automation output is enough for internal follow-up triage, but not for public Discovery visibility, LLM export, or certified gateway routing.

PubFi friction relief

Docs

Jun 19, 2026

Source friction: Blockchair public documentation evidence is recorded in the checked-in Discovery index.
PubFi relief: PubFi Discovery retains the public evidence as a noindex evidence profile and separates it from gateway certification.
