Capabilities

Tools 32

confirm_ownership_proof

Confirm a one-hour domain challenge with the same private requester key. Exact HTTPS origin and path must match. Returns a 90 day listing-control credential; identical retries recover that grant. A new proof revokes prior credentials. Confirmation does not approve branding or change grades. For a pending private contact, retry the original challenge_id/requester_key with contact_code. For a correction, use update_id and its private requester_key; an exact update-bound domain file queues review without publishing the proposed fields. Never signs payments.

Discovered
export_listings

Export up to 10000 visible x402 directory services with attributed source facts, measured health and grade history, first seen, scan counts, provenance and explicit truncation. Returns gzip+base64 JSON and a digest; large results use a 60 second signed download URL. Costs 0.25 USDC on Base or Solana. Reuse the original body and payment proof for exact 30 day result recovery. Never signs payments.

Discovered
get_scan_report

Read a completed public cached report by report_id. Reports expire after 24 hours; this tool never purchases a replacement.

Discovered
get_scan_status

Read a conformance job state with job_id and recovery_capability. Polling never starts work or settles payment.

Discovered
get_service

Get a complete public service or operation contract by slug, operation ID, name, or endpoint URL.

Discovered
get_trial_access

Get the service request and standard wallet-auth instructions. First signed execution enrolls automatically; no wallet funds or payment required.

Discovered
get_trial_offer

Read the adjustable free-use offer, wallet authentication, allowance and explicit paid transition.

Discovered
list_categories

Read categories present in visible identity-reviewed directory listings. Never signs payments.

Discovered
list_conformance_checks

Read the versioned 25-check linter and separate 14-check compliance catalogs, grading rules and unknown-evidence semantics.

Discovered
list_grade_changes

Read ordered new, grade_changed and rescanned events with previous grades and scores. Default 200, maximum 1000; signed watermark cursors. History retains 30 days or 50000 events; expired cursors return 410. Costs 0.01 USDC per page on Base or Solana. Use a fresh idempotency key per page; retain the original body and proof for exact recovery. Never signs payments.

Discovered
list_networks

Read canonical network identifiers in visible directory routes. Imported network claims are attributed and unverified until observed. Never signs payments.

Discovered
list_offer_changes

Read changes observed in unsigned payment challenges. Before/after fingerprints preserve payout privacy. A drained cursor advances to new observations on later polls; retain it. No paid delivery is inferred. Never signs payments.

Discovered
referral_accept_terms

Accept a newer version of the referral terms to keep earning. arguments: terms_version and terms_digest from referral_program. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
referral_acknowledge

Mark notices already served by referral_notices as read up to a cursor. arguments: cursor (integer) and optional private_cursor. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
referral_notices

Read published program notices and the referrer's private account events. arguments: optional cursor, limit (1-50) and private_cursor. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
referral_program

Read current Mekler referral availability, terms and commission offer.

Discovered
referral_receipts

Page through a referrer's commission receipts, oldest first. arguments: optional cursor (last seen) and limit (1-50). Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
referral_register

Register a wallet as a Mekler referrer and receive a referral code. arguments: terms_version and terms_digest from referral_program, which explicitly accept those exact terms. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
referral_rotate

Move a referral registration to a new wallet without losing history. arguments: old_wallet and new_wallet; then send proof (old wallet) and new_proof (new wallet). Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
referral_status

Read a registered referrer's code, referral link, accepted versus current terms and whether action is required. arguments: none. Call without proof to get a SIWx challenge, sign it with the referrer wallet, then call again with proof. No payment is authorized.

Discovered
reissue_owner_token

Request one email-based ownership-credential replacement for an existing verified private contact. POST origin for a uniform 202 response whether eligible or not. POST the same origin and recovery_code to confirm within 15 minutes. Domain control and original ownership scope are checked; success replaces the prior credential without extending the original 90 day expiry. The code is single-use with idempotent recovery of the same replacement. Revoked/expired grants or changed domains need a fresh ownership proof. Never put a recovery code or control credential in a URL. Never signs payments.

Discovered
request_listing_update

Request a free reviewed listing correction with X-Mekler-Listing-Control, current revision, a fresh private requester_key and exact changes. Reuse that same requester_key and identical body after an uncertain response; it pins one request, and changed input conflicts. A verified private email is required. Name/description/category, a same-origin website URL and the full replacement active endpoint list (up to 50 GET/POST paths) are supported. Publish the returned change-bound HTTPS verification file and confirm update_id within 72 hours through confirm-ownership-proof. Confirmation queues review; it never publishes raw submitted text. Pending reviews expire after seven days with a private outcome. Removed-route history is retained. action status with listing_id or origin reads private controls; optional request_id reads that correction outcome. Private data never enters public directory projections. Never signs payments.

Discovered
retrieve_health_checks

Page through fixed safe monitoring observations for one listing or the whole visible catalog. Current hiding and attribution controls apply to retained history. No captured target body, contact or payout address is returned. Never signs payments.

Discovered
retrieve_listing

Read one visible directory listing, attributed source assertions, measured reachability, endpoint offers and available linter grades. Imports start ungraded; identity-reviewed business wording does not verify seller claims or paid delivery. Never signs payments.

Discovered
retrieve_listing_history

Page through Mekler uptime, latency or observed price history for one listing. Raw history retains 30 days; UTC daily aggregates are retained indefinitely. Unknown input/auth/rate-limit observations are excluded from uptime denominators. This is configuration/reachability evidence, not paid-delivery proof. Never signs payments.

Discovered
rotate_trial

Write: request a wallet-rotation challenge with old_wallet/new_wallet/request_id; then submit old_proof/new_proof signed with both keys. Usage is preserved.

Discovered
scan_origin

Start or recover an asynchronous x402 conformance scan. For new origin-only calls, this MCP tool defaults to quote_mode fast and returns an unsigned 402 quote without starting a scan. Capability-only recovery requires the original input or proof; use get_scan_status for capability polling. Resend the same arguments with payment_signature only after independent payment authorization. Supplying idempotency_key without quote_mode retains compute-first admission. Save the job/capability and poll. Never signs payments.

Discovered
search_listings

Find x402 services imported from attributed catalogs or scanned by Mekler. Filter by task text, host, category, network, source, tier, grade or owner control. Unknown grades, prices and health remain unknown. Payment-ready means a recent valid unsigned challenge; it does not certify useful paid delivery. Immutable cursors retain ordering while current privacy controls still apply. Never signs payments.

Discovered
search_services

Find Mekler paid operations for a task, including exclusions and useful combinations.

Discovered
start_ownership_proof

Start a one-hour domain challenge bound to your private random 32-byte requester key in lowercase hex. Publish the returned JSON exactly at its HTTPS well-known URL. Keep the requester key private. An imported directory listing or completed scan is required before confirmation. No payment or target credentials are sent. Optionally supply contact_email and email_consent true for transactional verification/recovery/outcome messages. Contact stays private and must be verified by a mailed code after domain confirmation. No message is sent before successful domain proof. Never signs payments.

Discovered
summarize_directory_status

Read measured online, degraded, offline and unknown states, delisted count and latest completed monitoring cycle. Missing checks remain unknown; this does not certify paid delivery. Never signs payments.

Discovered
update_listing_preferences

Use X-Mekler-Listing-Control and the expected revision to hide a listing, suppress branding or revoke access. Domain proof is rechecked after seven days; failed, stale, revoked or expired credentials deny control. Concurrent writes return 409. Suppression affects current reads, new exports/feed pages and old search cursors; previously purchased snapshots remain recoverable. Never signs payments.
