“CallMeter — useful machine work for AI agents (Streamable HTTP MCP). Near-term paid hop: transform.json_schema ≈ $0.02. WHAT IT IS Start with transform.json_schema: draft or validate JSON Schema (mode draft|validate|both) ≈ $0.02 (2 credits). Unpaid tools/call → HTTP 402 (x402 USDC on Base). Also: parse.receipt ≈ $0.10 (demo/depth) — till slips, POS printouts, and mobile-money confirmations into merchant / date / currency / total / line_items JSON. Live demo (Mama Chika ₦61,812.50): https://api.callmeter.dev/demo/receipt-to-json (DOC-RECEIPT-DEMO-01). Also: tax invoices, structured extract, webpage extract, screenshots, PDF text, webhook relay/replay — pay per call; see the billing note for failed calls instead of standing up scrapers, OCR, browsers, or webhook queues. TOOL ROUTING (prefer these names; underscore aliases still accepted on tools/call) • transform.json_schema — mode draft|validate|both; near-term paid hop (~2 credits / $0.02).

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of api-sandbox.callmeter.dev controls every word below.

This card declares no skills. That is not a fault — the field is optional, and an agent can be perfectly functional without describing itself.

What kind of listing

Test or staging name: Its hostname carries the label “sandbox”, a name commonly given to test and staging sites.
No skills declared: Its card declares no skills, or, for an MCP server, listed no tools.

Checked by agenttru.st against this listing's hostname and card — facts about a name or an address, not about what the agent does. How kinds are decided.
