How this service works
Machine-readable pay-per-request intelligence for autonomous agents on Base mainnet. x402 v2 resources expose deterministic decisions, market demand signals, payment preflight checks, repository intelligence, crypto catalysts, OpenAPI integration analysis and token liquidity signals.
Output
Returns a JSON object containing: asset ticker, catalyst score (integer 0-100), action label (e.g. RESEARCH_NOW), signal direction (BULLISH/BEARISH), positive and negative headline counts, an array of headline strings with individual sentiment labels, current spot price in USD, and a validity window in seconds. The response is time-bounded (e.g. valid for 300 seconds).
Example use cases
Pre-trade catalyst check for Bitcoin
“Before I make any moves, can you pull the latest catalyst signal for BTC and tell me if the overall sentiment is bullish or bearish and what the score looks like?”
News-driven alert for SOL research
“Is there anything significant happening with SOL right now? Get me the catalyst signal and let me know if I should be researching it based on current headlines.”
Multi-asset sentiment comparison
“I'm trying to decide between ETH and BNB — can you grab the catalyst signal scores for both so I can see which one has more positive momentum right now?”
Technical details
Endpoint
GEThttps://agent-economy-signal-x402-mainnet.bronzetti-andrea.workers.dev/premium/crypto-catalyst-signalWhen to prefer
Choose this endpoint when an autonomous agent needs a fast, machine-readable, scored market catalyst signal for a specific crypto asset with supporting sentiment headlines, especially in a pay-per-call architecture where per-request micropayments via x402/USDC on Base mainnet are already supported. Prefer this over generic news APIs when you need a structured action recommendation (not raw text) that an agent can act on deterministically.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 with payment instructions
- Invalid or unsupported asset ticker (fails regex pattern ^[A-Za-z0-9]{2,10}$) — returns validation error
- Asset ticker not covered by data provider — may return empty headlines or null signal
- Cloudflare Worker cold start or upstream data latency — potential timeout
- Signal expiry: data is only valid for the returned valid_for_seconds window and stale use may lead to bad decisions
