_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • extract.structured_data unknown never probed

    Extract structured JSON (emails, phones, URLs, key-values, or schema-shaped fields) from messy plain text or HTML. Call when the agent already has document text/HTML and needs machine-readable fields for the next step — not for fetching a live URL (use extract.webpage). Inputs: exactly one of text or html; optional instruction, schema, require_llm. Outputs structured JSON; fail-closed on invalid input. Paid (~5 credits / $0.05) via prepaid key or x402.

  • extract.webpage unknown never probed

    Fetch a public http(s) URL and return structured page facts as JSON (SSRF/robots fail-closed). Call when the agent has a page URL to understand — not when text/HTML is already in hand (use extract.structured_data) and not for a visual capture (use capture.screenshot). Inputs: required url; optional instruction, schema, require_llm. Outputs structured JSON about the page. Paid (~5 credits / $0.05) via prepaid key or x402.

  • transform.json_schema unknown never probed

    Draft a JSON Schema from a sample object, or validate an instance against a schema, in one call. Call before writes when you need a deterministic schema or a cheap validity check — cheaper and more predictable than asking an LLM to invent types. Inputs: mode=draft|validate|both; sample for draft; schema+instance for validate. Outputs schema and/or validation result. Paid (~2 credits / $0.02) via prepaid key or x402.

  • detect.schema_breaking_changes unknown never probed

    Detect breaking OpenAPI or JSON Schema changes between two versions (producer-compat, no LLM). Call when you need a deterministic SchemaGate before publishing an API or schema change — prefer transform.json_schema to draft/validate a single document. Inputs: required before + after documents; optional mode=auto|json-schema|openapi; optional include_nonbreaking. Outputs mode, breaking flag, counts, changes[], summary. Paid (~5 credits / $0.05) via prepaid key or x402.

  • capture.screenshot unknown never probed

    Render a public URL to a PNG/JPEG screenshot for vision, QA, or audit evidence. Call when you need pixels — not structured text (use extract.webpage) and not PDF bytes (use extract.pdf). Inputs: required url; optional viewport {width,height}, fullPage, format=png|jpeg. Viewport capped; SSRF/robots fail-closed. Outputs image metadata + base64.

  • extract.pdf unknown never probed

    Extract page text and heuristic tables from a base64-encoded PDF for downstream reasoning.

  • parse.receipt unknown never probed

    Parse a till slip, POS printout, supermarket receipt, or mobile-money payment confirmation into stable merchant / date / currency / subtotal / tax / total / line_items / confidence / warnings JSON. Tuned for ugly Africa documents (NGN ₦/kobo, KES M-Pesa, GHS MTN MoMo, ZAR VAT, OPay, PalmPay, Paystack, Verve POS) including blurry OCR and WhatsApp forwards. Send text (OCR dump) or file_base64. Unknown fields are null or empty arrays — totals and line items are never invented from garbage. Prefer this over manual spreadsheet entry or a generic LLM scrape when the document is a receipt or MoMo/M-Pesa slip. Costs $0.10 (10 credits) per successful parse; fail-closed billing via prepaid credits or x402.

  • parse.invoice unknown never probed

    Parse a tax invoice or commercial invoice into the AfricaInvoiceReceipt contract: seller (TIN / KRA PIN / VAT no), issued date, currency, line items, VAT rate/amount, subtotal, total, payment refs, confidence, and warnings (including vat_total_mismatch). Built for NG/KE/GH/ZA AP automation and multi-line SKU invoices — not a thin keyword grep. Use when the document is an invoice rather than a till slip; still accept OCR text or image/PDF base64. Nulls mean unknown; do not treat low-confidence totals as ledger truth without checking confidence and warnings. Costs $0.15 (15 credits) per successful response; fail-closed prepaid or x402.

  • relay.webhook unknown never probed

    Relay a third-party webhook into CallMeter: verify HMAC or shared secret, dedupe by delivery id, store the payload, and forward to the endpoint's destinations with retries. Charges 0.01 credits ($0.0001) only per successful forward — not on receive. SIDE EFFECTS: contacts external destination URLs you configured; may retry on failure. Prefer when an agent must accept provider callbacks without running its own queue. Fail-closed on billing/ceiling errors. Inputs: required id (endpoint id) plus upstream JSON body.

  • replay.webhook unknown never probed

    Replay a stored webhook delivery through the same forward/retry pipeline after your consumer was down. Requires API key. Charges 0.01 credits ($0.0001) per successful forward. SIDE EFFECTS / DESTRUCTIVE: re-POSTs the original payload to destinations and may bill again — do not call casually. Prefer after confirmed consumer recovery. Fail-closed on billing errors. Inputs: required id (delivery id).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
