LION Enrichment + TX Bundle (x402, keyless)
x402
LION Enrichment + TX Bundle (x402, keyless) is a paid API for AI agents from lion-x402.lionmaster-operations.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-12).
Returns a combined entity enrichment score and on-chain transaction receipt bundle for a named entity, paid per-call via x402 USDC on Base with no API key required.

How this service works
Keyless off-chain and on-chain data for AI agents. No API key, no signup - payment is the only gate. Pay-per-call in USDC on Base via x402.
Output
A JSON object containing: entity name, attention score (0-1), momentum score, a decoded on-chain transaction receipt (to/from/status/gasUsed/blockNumber/decoded calldata), payment proof metadata, provenance hash with timestamp, combined price, and a disclaimer. Also includes the asset IDs for the enrichment and tx receipt components.
Example use cases
Entity momentum score for research pipeline
“Grab the combined enrichment and on-chain receipt bundle for Uniswap — I need the attention score, momentum signal, and decoded transaction calldata in a single call, no API key, just pay per call in USDC.”
Decoded transaction receipt with entity signals
“Look up the enrichment bundle for Ethereum Foundation and pull back the decoded on-chain transaction receipt alongside the attention and momentum scores — I want everything in one x402 payment without having to manage any credentials.”
High-frequency keyless on-chain data lookup
“Fetch the full enrichment and transaction context bundle for Chainlink using the volume1000 discount tier — I need the provenance hash, momentum score, and the decoded calldata from the latest receipt all bundled together.”
Technical details
Endpoint
GEThttps://lion-x402.lionmaster-operations.workers.dev/api/x402/enrichment-tx-bundle-json?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs both entity-level enrichment signals (attention, momentum) AND on-chain transaction context in a single low-cost call, without managing API keys or subscriptions. Ideal for high-frequency research pipelines where per-call USDC micropayment via x402 is preferable to OAuth or key-based auth, especially when volume discounting matters.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 with payment requirements
- Invalid or unsupported entity name — may return empty or null enrichment fields
- Network congestion on Base causing delayed tx receipt lookup
- Invalid volume tier parameter — falls back to default $0.005 rate
- Stale data if the as_of timestamp is significantly behind real-time
