Blockchair OSINT integration
On-chain address, transaction, and block dashboards across major chains.
Blockchair indexes Bitcoin, Ethereum, and other public chains into dashboard views for addresses, transactions, and blocks. SearchIn calls those dashboards at $0.01 per lookup so balance, first/last seen, inputs/outputs, and block contents sit on the same desk as your other identifiers. Queries use chain plus identifier (for example bitcoin 1A1zP1…).
How the Blockchair integration works
What happens between pressing run and reading a result.
- 1Choose Crypto address, Transaction, or Block and pick a supported chain.
- 2SearchIn calls Blockchair’s dashboard endpoint for that chain and identifier.
- 3Address lookups return balance and recent txs; transaction lookups return fees and IO; block lookups return header fields and a capped tx list.
- 4Related addresses, txs, and blocks become graph nodes you can pivot across Blockchair.
Supported inputs & pricing
Prices are USD. LeakRadar includes 1,000 credential unlocks in the query price, then $0.50 per extra 1,000. OSINT Industries is $0.60 plus optional premium modules at $1.80. Other integrations are flat per query. Full SearchIn rates are on pricing.

Why run Blockchair through OSINTverse
You can always buy Blockchair directly. Here is what changes when the same data comes through SearchIn instead. Full write-up: OSINTverse vs Blockchair.
| Blockchair directly | Through OSINTverse | |
|---|---|---|
| Getting started | Blockchair exposes a public blockchain API with a daily free request ceiling for unauthenticated use, and optional API keys for higher volume. SearchIn uses the dashboard endpoints and does not require you to hold a Blockchair key for ordinary testing volume. | Sign in, top up from $10, and run Blockchair the same minute — no vendor contract, seat, or sales call. |
| What a query costs | Plan, credit pack, or contract pricing set by the vendor and paid up front. | Pay per query from your prepaid balance — Blockchair starts at $0.01 for crypto address lookups, with the exact price shown before you run it. |
| Failed lookups | Handled under the vendor's own credit and refund policy. | Automatically refunded to your wallet — a search that fails upstream after billing is not charged. |
| Output format | A vendor-specific response shape you normalise and render yourself. | Normalised result panels plus the raw JSON, returned by the same POST /v1/search contract as every other integration. |
| Cross-source work | Copy-paste between vendor dashboards to follow a lead into another dataset. | Results join one case graph, so you can pivot an entity into any of the other 14 integrations in a click. |
| Running it for a team | Per-seat or per-account access, billed and administered per analyst. | One shared team wallet with roles, provider allowlists, enforced MFA, and audit history — no per-seat fee. |
| Volume work | Script the vendor API yourself, including retries, polling, and rate handling. | Bulk search takes up to 50 queries across selected providers in one submission (max 100 jobs), with per-job status and partial-failure handling. |
What every integration inherits
Good to know
Constraints worth reading before you spend a query.
You must supply the chain. An address that is valid on more than one network needs the correct slug.
Long transaction and block lists are capped in the structured panel; raw JSON keeps the upstream payload.
Blockchair’s free daily ceiling is IP-limited. Heavy production traffic needs a Blockchair API key on the SearchIn backend.
Going direct still makes sense at sustained high volume on a single source. Blockchair exposes a public blockchain API with a daily free request ceiling for unauthenticated use, and optional API keys for higher volume. SearchIn uses the dashboard endpoints and does not require you to hold a Blockchair key for ordinary testing volume. Through SearchIn you trade that commitment for per-query pricing across 15 integrations.

Why use OSINTverse instead of Blockchair directly?
Blockchair exposes a public blockchain API with a daily free request ceiling for unauthenticated use, and optional API keys for higher volume. SearchIn uses the dashboard endpoints and does not require you to hold a Blockchair key for ordinary testing volume. On OSINTverse you pay per query from one prepaid wallet, failed searches are refunded automatically, results are normalised into an investigation graph you can pivot from, and the same POST /v1/search call reaches every other integration. A $0.01 query returns a structured address, tx, or block card — no Blockchair explorer tab for a one-off check.
What are the limits of Blockchair on SearchIn?
You must supply the chain. An address that is valid on more than one network needs the correct slug. Long transaction and block lists are capped in the structured panel; raw JSON keeps the upstream payload. Blockchair’s free daily ceiling is IP-limited. Heavy production traffic needs a Blockchair API key on the SearchIn backend.
