http_inspectread-only | 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. |
json_normalizeread-only | Paid $0.001 USDC on Base or Solana canonical JSON normalization plus SHA-256 digest. |
json_schema_validateread-only | Paid $0.001 USDC on Base or Solana deterministic JSON Schema subset validation. |

mcp_preflightread-only | 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. |
openapi_selectread-only | 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. |
payment_guardread-only | 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. |
procureread-only | 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. |
provider_bootstrapread-only | 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. |
provider_launch_checkread-only | 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. |
resolveread-only | 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. |
sha256read-only | Paid $0.001 USDC on Base or Solana SHA-256 digest of bounded UTF-8 text. |
sha512read-only | Paid $0.001 USDC on Base or Solana SHA-512 digest of bounded UTF-8 text. |

sponsorship_inforead-only | 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. |
tool_contractread-only | 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. |
url_parseread-only | Paid $0.001 USDC on Base or Solana absolute URL parser. |
uuid_v4read-only | Paid $0.001 USDC on Base or Solana UUID v4 generation, up to 20 IDs. |
verified_resolveread-only | 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. |
x402_payment_preflightread-only | 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. |
x402_pingread-only | Paid $0.001 USDC on Base or Solana no-body settlement canary for funded agents. Returns a timestamped pong only after successful x402 payment to verify wallet, facilitator, payment, and delivery end-to-end. |
