The specific endpoint at `/v1/services/svc_cd3efb354cd24307/quote` is intended to request a quote for a variable-priced service — i.e., services whose cost depends on the scope of work rather than having a fixed price. This is part of the402.ai's \"quote_required\" pricing model, where agents submit requirements and receive a price proposal before committing to purchase.\n\nThe broader platform exposes a rich API surface: a free service catalog for discovery, fixed-price instant purchases, async job queues for human-delivered work, conversation threads between agents and providers, subscription plans, digital product sales, wallet reputation scoring, referral programs, and pre-funded balance management. All paid endpoints use x402 (HTTP 402 + signed EIP-3009 USDC authorization via the `X-PAYMENT` header) or alternatively a pre-funded balance via `X-BALANCE-AUTH`. Payments settle in USDC on Base L2.\n\nNote: During probing, this specific endpoint returned 404 on both POST and GET, meaning it did not present the expected 402 payment challenge. The service ID `svc_cd3efb354cd24307` may have been delisted or the `/quote` sub-route may not be active. The broader platform API at api.the402.ai is live (root returns 200, OpenAPI spec is available), so the platform itself is operational even if this particular service listing is not currently reachable.","tags":[],"capabilities":["service-quote-request","variable-pricing","x402-payment","usdc-base-l2","agent-marketplace","service-discovery","async-job-tracking","human-service-dispatch","wallet-reputation","subscription-management","digital-product-sales"],"categories":["marketplace","payments","agent-infrastructure"],"synonyms":["the402 quote endpoint","x402 service marketplace","agent service quote","variable price service","USDC micropayment marketplace","AI agent marketplace","service pricing request","the402.ai API","agent-to-human services"],"warnings":["Endpoint returned 404 on both POST and GET — the service ID may be delisted or the /quote sub-route may not exist","The /quote path is not present in the platform's OpenAPI specification; only /purchase and /inquire are documented for services","All OpenAPI response schemas are generic `type: object` with no field-level detail","Example request and response JSON are inferred and not sourced from documentation"],"endpointUrl":"https://api.the402.ai/v1/services/svc_cd3efb354cd24307/quote","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x21bCE104282d6a089539C34aDddE152D42A02D0e","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://api.the402.ai/v1/services/svc_cd3efb354cd24307/quote","description":"Request a quote for a variable-priced service","outputSchema":{"input":{"type":"http","method":"POST","discoverable":true}},"maxAmountRequired":"1000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The specific /quote endpoint returned 404 during probing (not a 402 challenge), suggesting the service may be delisted or the route inactive.
