x402-agent-economy-lab-text-tools
Pay-per-call NLP micro-services settled in USDC via x402 on Base mainnet. Live endpoints and prices (verbatim from /.well-known/x402): /v1/sentiment $0.005 - sentiment label+score; /v1/entity-extract $0.004 - people, orgs, places, dates; /v1/summarize $0.008 - condensed summary; /v1/report $0.02 - combined analysis bundle; /v1/batch $0.02 - bulk sentiment. Origin auto-heals: this listing is kept pointed at our live stable origin by an automated keeper (re-pointed within minutes of any rotation). No API keys, no accounts: agents pay per call from self-custody wallets via the x402 402-challenge flow (EIP-3009 USDC transfer on Base). Honest status: zero sales to date.
