https://api.24klabs.ai Our Verdict
Gold402 Verified. Hand-reviewed and on the curated list — curation is the bar. The stamp means a human read this entry and the endpoint answered when we knocked. It is not a delivery test: we have not paid this service and graded what came back, so treat it as "reachable and speaks the protocol," never as "this is worth the money."
143 pay-per-call endpoints on one x402 v2 server, no account or API key: AI code work (explain, debug, review, security audit, automation scripts, MCP blueprints), text and document processing, image manipulation and OCR, weather/geocode/FX/crypto data, developer utilities (hashing, encoding, regex, cron, JSON/CSV/YAML/XML conversion, JSON Schema), and 17 finance calculators (amortization, NPV/IRR, Black-Scholes, liquidation price, impermanent loss, Kelly sizing). $0.001-$3.00 USDC on Base; six endpoints are tiered quick/standard/pro, the rest flat. All 143 knocked 2026-08-29 — 143 of 143 returned a live 402. ([Manifest](https://api.24klabs.ai/.well-known/x402.json))
