What it does

This endpoint retrieves comprehensive information about a specific blockchain transaction, including native cryptocurrency movements, ERC-20 token transfers, and NFT transfers with both historical and current USD valuations. It is part of Nansen's broader API suite for blockchain analytics and smart money intelligence.

The endpoint accepts a POST request with a chain identifier, transaction hash, and block timestamp. It returns detailed data including sender/receiver addresses with Nansen labels, native value transferred with dated and current USD prices, token transfer arrays with per-token USD values, and NFT transfer arrays with collection metadata. Supported chains include Ethereum, Base, Arbitrum, Solana, Polygon, BNB, and many others (24+ chains total).

Pricing is $0.01 per call via the x402 protocol, or 10 credits (free tier) / 1 credit (pro tier) when using a Nansen API key. The endpoint returns standard rate-limit headers and credits-remaining headers. Authentication is via API key or x402 payment signature. The API is documented with a full OpenAPI 3.1.0 schema.

Quality

0.88/ 1.00

Full OpenAPI 3.1.0 schema with detailed request/response models, clear pricing ($0.01/call via x402), endpoint confirmed live via 402 MPP challenge, and 24+ supported chains documented. Minor deduction: no crawled documentation pages beyond the API root, and response schema references are not fully resolved in the probe.

Warnings

  • —No external documentation pages were successfully crawled; docs endpoint returned 404
  • —Response schema uses $ref to TransactionLookupListResponse which is defined in components but example response is inferred from schema, not from a live call
