You pay per call with x402. ## Choose an outcome - Local Market Check: one paid package combines organic Google results, Maps listings, observed competitor domains and action tips for one keyword and location. Optional domain presence is limited to the returned sample. Start with https://agent.connskill.com/local-market-check.json and GET /v1/local-market-check-quote. - Domain ranking snapshot: use https://agent.connskill.com/domain-rankings.json to inspect one domain in the available ranking dataset; save the JSON for a separately approved later comparison. - Keyword demand check: use https://agent.connskill.com/keyword-research.json for search volume, CPC and advertising competition for your chosen terms. Advertising competition is not organic SEO difficulty. These are free buyer guides, not payment instructions or recurring subscriptions. Inspect current availability and approve one bounded purchase before paying. Local Market Check has one package price; do not buy its component calls again. ## Current status and updates Free status: https://agent.connskill.com/status.json. Process reachability is not payment or delivery proof. Check generatedAt, checkedAt and validUntil; stale or missing observations remain unknown. maintenance.active only describes the serving process. notices lists published planned windows; end_time_passed does not confirm resolution. Never infer another purchase is required from an outage. Published news: https://agent.connskill.com/news.json and https://agent.connskill.com/news.xml (German: /de/news.json and /de/news.xml). Drafts are not public. Human status page: https://agent.connskill.com/status. ## Free catalogue comparison Search https://agent.connskill.com/v1/service-search?q=seo or open https://agent.connskill.com/search. Queries stay local. Results cover only a bounded subset of CONNSKILL Directory and CDP Bazaar. Inspect coverage.sources for age, partial coverage and errors. Unknown billing units are not price-ranked. A source listing is not proof of availability, privacy compliance or a lower price. ## Free task templates Copyable tasks: https://agent.connskill.com/prompts (German: /de/prompts). Machine-readable catalogue: https://agent.connskill.com/prompts.json (German: /de/prompts.json). Local Market Check package: https://agent.connskill.com/local-market-check (German: /de/local-market-check). Free recipe: /local-market-check.json. One package purchase, current price from GET /v1/local-market-check-quote; no automatic repeat. Keyword demand check: https://agent.connskill.com/keyword-research (German: /de/keyword-research). Free recipe: /keyword-research.json. One separately approved keyword-metrics request; search volume and ads competition are not organic ranking difficulty. Domain ranking snapshot: https://agent.connskill.com/domain-rankings (German: /de/domain-rankings). Free recipe: /domain-rankings.json. Exactly one ranked-keywords call after separate cost approval. Save the original JSON for a later buyer-initiated comparison; no subscription or automatic repeat. First bounded search task: https://agent.connskill.com/local-search (German: /de/local-search). Free recipe: /local-search.json. Copying is not payment approval; check the current contract before one separately approved SERP Basic call. The templates are free; copying grants no purchase authority. Confirm any paid scope and spending limit with the user. ## How one call works 1. Send the request. Unpaid, it answers HTTP 402 with the exact price in `accepts[0].amount` (micro-USDC, so 30000 = 0.03 USDC) and the address in `accepts[0].payTo`. 2. Pay that amount in USDC on Base (eip155:8453) with an EIP-3009 authorization. Use a wallet-enabled x402 client with a spending limit. Hosted MCP forwards payment and wallet headers supplied by its caller; it does not sign for you. 3. Send the SAME request with the PAYMENT-SIGNATURE header for the first purchase. Manual payment, where supported: Before transferring funds, check that the target accepts manual payment and that the token-paying EOA wallet can sign EIP-191 messages. Use a complete JSON POST body and only ref query parameters. After one transfer, POST /v1/payments/challenge with purpose purchase, the token payer address and the exact target method, public path including query, x-payment-tx header and complete JSON body. Sign its exact message; send the returned extensions.sign-in-with-x.info fields plus address, chainId eip155:8453, type eip191 and signature as base64 JSON in Sign-In-With-X on that same target request. The challenge and wallet proof are free. Standard-x402 first purchases keep their PAYMENT-SIGNATURE flow. Private result retrieval: Do not pay or order again for an unresolved purchase. For a retained result, request a free fresh challenge from POST /v1/payments/challenge with purpose redelivery, the original token payer address, exact public POST path including query, original payment references and complete JSON body. Sign the exact challenge message and send the resulting Sign-In-With-X proof on the same request. This only reads an existing result. If it is unavailable or returns 409, open wallet support at /support; no new provider order is started. Both wallet-proof paths require a complete JSON body and only ref query parameters. Keep query order and percent-encoded bytes unchanged. Resolve incompatibilities before paying. Free endpoints need no payment at all. One free sample per endpoint per UTC day: add the header `x-free-sample: 1` on any endpoint priced 0.15 USDC or less.
