AgentResolver — Agent Commerce Health Monitoring

Free read-only information for tool/API/MCP providers about AgentResolver's explicitly labeled sponsorship pilot. Organic ranking remains independent; applying creates no purchase or financial commitment.

Free exploratory discovery. Use only when browsing possible tools/APIs/MCP services without needing a trustworthy execution choice yet. For an actual missing capability, prefer procure so required evidence fails closed and unresolved candidates can escalate to verification.

Free zero-state provider onboarding. Reads the fixed AgentResolver well-known manifest on one HTTPS origin, live-verifies selected same-origin x402 payment identities, returns an immediate providerOrigins procurement seed, and prepares caller-owned durable 402 Index registration actions. AgentResolver does not persist provider state or send the external registration.

CALL THIS when the agent's installed tools do not clearly satisfy the current task. Free open-world procurement across APIs, MCP, x402, L402 and MPP. Required compatibility evidence fails closed: AgentResolver returns no selected provider rather than guessing. When supported unknowns remain, the response can recommend the paid $0.02 verified_resolve step. Never authorizes spend.

Paid $0.001 USDC on Base or Solana SHA-512 digest of bounded UTF-8 text.

Paid $0.001 USDC on Base or Solana UTF-8 to Base64 encoding.

Paid $0.001 USDC on Base or Solana Base64 to UTF-8 decoding.

Paid $0.001 USDC on Base or Solana non-verifying JWT header/payload decode.

Paid $0.001 USDC on Base or Solana canonical JSON normalization plus SHA-256 digest.

Paid $0.001 USDC on Base or Solana deterministic JSON Schema subset validation.

Paid $0.001 USDC on Base or Solana absolute URL parser.

Paid $0.001 USDC on Base or Solana UUID v4 generation, up to 20 IDs.

Paid $0.001 USDC on Base or Solana deterministic slug generation.

Paid $0.001 USDC on Base or Solana deterministic SHA-256, SHA-512, HMAC-SHA256, Base64 encode/decode, or non-verifying JWT decode. x402-aware MCP clients can authorize and settle inside this tool call.

Paid $0.001 USDC fail-closed payment authorization preflight. Use immediately before an autonomous agent signs a target x402 payment. Returns eligible/blocked, exact observed payment terms, reason codes, evidence receipt and stable fingerprints. The caller retains sole spending authority.

Paid $0.001 USDC on Base or Solana transaction-path gate for autonomous buyers. Returns eligible/blocked, exact target payment terms, fail-closed reason codes and verifiable evidence before caller authorization. AgentResolver never requests a private key, signs the target payment, or custodies/forwards target funds.

Paid $0.001 USDC on Base or Solana verify-before-pay endpoint safety check: payTo verification, quote price, network, asset, resource binding and x402 challenge compliance before an agent authorizes spend. POST probes require explicit caller opt-in because an unprotected endpoint could have side effects.

Paid $0.005 USDC on Base or Solana deterministic JSON-schema compatibility check between one tool output and the next tool input. Returns exact incompatibility reasons and conservative normalized mappings. x402-aware MCP clients can authorize and settle inside this tool call.

Paid $0.005 USDC on Base or Solana selection of the best operation from one public JSON OpenAPI spec for a stated goal. Returns a compact execution-ready contract. x402-aware MCP clients can authorize and settle inside this tool call.

Paid $0.001 USDC on Base or Solana live MCP endpoint preflight for reachability, compatibility, latency, server metadata and tool inventory. x402-aware MCP clients can authorize and settle inside this tool call.

Paid $0.005 USDC on Base or Solana audit of a public website for agent discoverability and machine-readable integration signals. x402-aware MCP clients can authorize and settle inside this tool call.

Paid $5 USDC seller-side agent distribution pack for API/MCP discoverability: live discovery audit, ready-to-commit agent-readable artifacts, and a prioritized API/MCP distribution sequence.

Paid $0.05 USDC seller-side agent-distribution entry check: verify provider readiness and the live x402 contract, then use the $5 Distribution Pack when discoverability artifacts or launch fixes are needed.

PAID $0.02 USDC verification step. Use after procure returns no proven selection / eligible_with_unknowns, or immediately before trusting an unfamiliar external candidate when live evidence is required. Re-checks supported endpoint, MCP, x402 and contract evidence and returns a fail-closed recommendation. Call only when the host independently authorizes the displayed spend.

Paid $0.05 USDC on Base or Solana batch live verification for 2–4 capability decisions using unpaid MCP and x402/HTTP evidence. x402-aware MCP clients can authorize and settle inside this tool call.
