### Tool changes

- 2026-11-08 `wafermap_discover` changed (description)
  - before: Searches the open x402 Bazaar index (run by Coinbase CDP) for paid APIs outside Wafermap's own catalog, such as weather, web search, data enrichment or token prices. Returns each service's URL, HTTP method, price, accepted networks, an example input and whether Wafermap can pay it (payable = accepts USDG on Robinhood Chain or USDC on Solana, Base, Arbitrum, Polygon, Arc or Soneium). Use it when no Wafermap resource fits the task. Free, no payment needed.
  - after: Searches the open x402 Bazaar index (run by Coinbase CDP) for paid APIs outside Wafermap's own catalog, such as weather, web search, data enrichment or token prices. Returns each service's URL, HTTP method, lowest price (priceUsd), the price on each network Wafermap can pay (prices; sellers may charge more on some chains), accepted networks, an example input and whether Wafermap can pay it (payable = accepts USDG on Robinhood Chain or USDC on Solana, Base, Arbitrum, Polygon, Arc or Soneium). Use it when no Wafermap resource fits the task. Free, no payment needed.

- 2026-11-05 `wafermap_call` changed (description)
  - before: Runs one Wafermap resource and pays its exact USD price over x402, in USDG on Robinhood Chain or USDC on Solana, Base, Arbitrum or Polygon. Send a signed x402 v2 PaymentPayload in params._meta["x402/payment"]; without it the tool returns isError with the payment requirements (price, networks, payTo) to sign. The work runs before the payment settles, so failed calls are never charged; a successful call returns the result plus a receipt with the transaction hash in _meta["x402/payment-response"]. Agents without an x402 wallet can use the Wafermap CLI (`wafermap mcp`), which pays automatically within spending caps.

- 2026-11-05 `wafermap_resources` changed (description, inputSchema)
  - before: Lists Wafermap's pay-per-call resources (35 of its own) and the live Inference Marketplace listings (ids "m/<name>", run and paid directly to their seller, provider "community") with id, name, category, USD price and a one-line summary. Use it first to find the right resource id; then read its input schema with wafermap_resource_schema and run it with wafermap_call. Categories: LLMs, image generation, audio (speech and transcription), vision, web (reading and translation), on-chain data on Robinhood Chain and Base, tokenized stocks, Polymarket prediction markets and content tools. Free, no payment needed.
  - after: Lists Wafermap's pay-per-call resources (38 of its own) and the live Inference Marketplace listings (ids "m/<name>", run and paid directly to their seller, provider "community") with id, name, category, USD price and a one-line summary. Use it first to find the right resource id; then read its input schema with wafermap_resource_schema and run it with wafermap_call. Categories: LLMs, image generation, audio (speech and transcription), vision, web (reading and translation), on-chain data on Robinhood Chain and Base, tokenized stocks, Polymarket prediction markets, content tools, and workflows (several resources in one paid call: token due diligence, stock token brief, launch scan). Free, no payment needed.

- 2026-10-28 `wafermap_resource` removed
  - One resource: price in USD, input JSON Schema, an example input and what it returns. Free.
- 2026-10-28 `wafermap_tokens` changed (title, description, inputSchema) **meaning changed**
  - before: Tokens the Wafermap wallet can swap through KyberSwap: ETH, WETH, the stablecoin and, on Robinhood Chain, every stock token. Free.
  - after: Lists the tokens a Wafermap wallet can swap through the KyberSwap aggregator on one network, with symbol, name and contract address. On Robinhood Chain this includes ETH, WETH, USDG and every Robinhood stock token (TSLA, NVDA, AAPL…); on Base it includes ETH, WETH and USDC. Use it to resolve a ticker to its contract address before quoting or executing a swap with the Wafermap CLI. Read-only and free; it does not trade.
- 2026-10-28 `wafermap_discover` changed (title, description, inputSchema) **meaning changed**
  - before: Search the open x402 Bazaar index for third-party paid APIs (weather, search, enrichment, data…). Services marked payable accept USDG on Robinhood Chain or USDC on Base. Free.

- 2026-10-28 `wafermap_call` changed (title, description, inputSchema)
  - before: Run a Wafermap resource and pay its exact price over x402 (USDG on Robinhood Chain or USDC on Base). Put a signed x402 v2 PaymentPayload in params._meta["x402/payment"]. Without it, the tool returns the payment requirements. Failed calls are never charged. For automatic payments from a local wallet with spending caps, use the Wafermap CLI: `wafermap mcp`.

Free, no payment needed.
- `wafermap_resource_schema`: Returns everything needed to call one Wafermap resource: its USD price, the JSON Schema of its input, a ready-to-use example input, what it returns, and its HTTP endpoint. Use it after wafermap_resources and before wafermap_call so the input is valid (invalid input is rejected before any payment). Free, no payment needed.
- `wafermap_tokens`: Lists the tokens a Wafermap wallet can swap through the KyberSwap aggregator on one network, with symbol, name and contract address. On Robinhood Chain this includes ETH, WETH, USDG and every Robinhood stock token (TSLA, NVDA, AAPL…); on Base it includes ETH, WETH and USDC.
